Hi, i'm starting this thread to discuss the
support for stipples in windows port.
My ideas in how this can be done is using
the w32term.c functions for drawing rects,
i tested using w32_fill_rect but it doesn't
work, i don't know how it works.
The elisp snippet that i'm using for test this is this:
```
(let* ((w (window-font-width))
(stipple `(,w 1 ,(apply #'unibyte-string
(append (make-list (1- (/ (+ w 7) 8)) ?\0)
'(1))))))
(insert "\n" (propertize " " 'face `(:background "red"
:foreground "blue" :stipple ,stipple))))
```
The closest thing i got was using w32_draw_rectangle
inside w32_draw_glyph_string_background
but for some reason it freezes and crashes after evaling
the snippet, I'm not sure if it is related to the way I did it or is
anything related to GC.
Below this mail can you get the patch for test it
(Also i'm sorry if the patch is too long i accidentally
formatted it with clang-format)
Also can i ask what is the purpose of this line?
```
# include "bitmaps/gray.xbm"
```
Thanks.

Please undo the reformatting, it resulted in an ocean of unrelated
changes that completely drown your real changes, and make it very
hard, almost impossible, to review the patch. Especially since you
are asking why the code crashes, the answer to which is likely to be
in some subtle aspect of the code.

It comes from xterm.c, and defines gray_bits, gray_width, and
gray_height, which xterm.c uses for implementing the stipple. See in
xterm.c for the details.

You appear to fundamentally misunderstand the nature of stipples and
which component bears the burden of its implementation. A stipple
pattern is a repeating bitmap pattern that replaces the solid background
color of a face, in which pattern "on" pixels are tinted the foreground
color of the face, and off pixels the background, and whose repetition
is such that its tiles (instances of its bitmap) extend from a
conceptual "origin" defined by the position of the drawable. In X,
stipples are natively supported by graphics primitives, being simply
properties of the GC (graphics context), to wit, the fill style, the
stipple bitmap, and the tile/stipple origin offset, which three
properties are direct determinants of the imagery produced by
polygon-filling or stroking operations, and are configured some time
before x_draw_glyph_string_background is invoked, relieving the latter
of all responsibility, with respect to stipples, but enabling the
prepared stipple pattern when appropriate. This is the reason that the
disabled code in the related W32 function is no more than a few calls to
XDrawRectangle, but as the supporting infrastructure, both in Emacs and
the display server, is not present on MS Windows, enabling just this
code, even if it does not crash, serves little purpose.
Your task is not to uncomment this handful of lines, but to establish
how best to express these X concepts in terms of primitives available on
MS Windows, and implement them in a manner appropriate for _Windows_,
without regard to the specifics of the X implementation.

I suggest reverting the portions of the patch that are the work of
clang-format, as we cannot accept such drastic whitespace changes, and
the substantive changes simply vanish in their midst.

It includes the bitmap image, bitmap/gray.xbm, which is a C header
defining an array and several parameters. This is not relevant on
Windows.
HTH.

Thank you for explain me, I was a little confused in how stipples works.

Thanks, as far as i understood then should not i touch or even edit those
lines?
I was thinking in define them (since them are only available in X) inside
the same file, similar in how pgtkterm.c or androidterm.c does, i think i
should check again `image_create_bitmap_from_data' and
`prepare_face_for_display' definitions.

Thank you, i've reverted the changes done by clang-format, reviewing the
test that i made i got notice it works a bit similar to `box' property and
not to a stipple, but anyways i'm sending it here if it can be useful.

Thank you for the help, I wasn't familiar with X.org stuffs (since I'm in
Windows and most of them are not available) and with C (specially in a big
project such as emacs).
But I have faith that I can help in this.

It helps not to dwell on the X implementation too long. You should
select whatever interfaces appear the most suitable on Windows, so long
as the logic around when to display stipples is preserved faithfully.
On Android, for instance, the relevant code exists in two functions
defined in EmacsGC.java, prepareStipple and blitOpaqueStipple, which are
nothing akin to the X implementation it emulates. The same is true of
haikuterm.c, haiku_draw_stipple_background, and BView_DrawBitmapTiled in
haiku_draw_support.cc.

Perhaps "pattern brushes" are the tool for the job?
https://learn.microsoft.com/en-us/windows/win32/api/wingdi/nf-wingdi-createpatternbrush
but please be careful not to use APIs introduced after the earliest
versions of MS-Windows we support, which I believe is Windows NT 4.0.

Thank you, i've read the documentation and i think it can also be useful, i
will do some test for see the result.

After some tests, i could execute the snippet sent in this thread without
crashes with something similar to a stipple (sadly i cannot send the patch,
i'm not in my computer), i tried using CreatePatternBrush, however it
needs the bitmap as a HBITMAP variable type, i've found some examples in
the same file (w32term.c) such as fringe bitmap that uses a HBITMAP var.
I would like to know any idea for make stipple bitmap as a HBITMAP (I'm not
sure if i should make it using CreateBitmap).
Also i would like to know if its a good idea remove XSetFillStyle from
w32_draw_glyph_string_background (
https://git.savannah.gnu.org/cgit/emacs.git/tree/src/w32term.c#n1271),
AFAIK it is only for set the fill-style which i dont think it's necessary
since i'm implementing the stipple fill-style inside a XFillRectangle
implementation which i'm working.
Thanks

That fragment is there only to show what xterm.c does for this, so
that the w32 code would follow the same paradigm. If you are
implementing the w32 code for doing that, the X-related code can be
removed.

Alright thanks, i've done some test, and now i could draw a bitmap inside
the propertized area, and now it fill/tile to all the area
(see below this email the attached patch for the work done).
However for this patch i'm using a defined bitmap and not from the
stipple one, i'll need to figure how to get the stipple width and height,
about the stipple data i still trying to figure how to use it since it's
doesn't work with `CreateBitmap' (i'm not sure what contains i've tried
to use `printf' for get `s->face->stipple' value in my console/terminal
but printf is not defined, is there a way for print values to the
console/terminal?).

[-- Attachment #1: Type: text/plain, Size: 885 bytes --]
I'm a bit stuck here, i could make to use the stipple bitmap, however it
doesn't uses background and foreground color from propertized string,
(and looks very weird).
The drawing works fine, but the problem is trying to get stipple bitmap,
and makes it work well.
One way that i thought for fix this is redefining bitmap stipple for
using same string fg and bg colors and bitmap width and height, but for
this i need the bitmap bits.
I found that image_create_bitmap_from_data also makes stipple bitmap
(https://git.savannah.gnu.org/cgit/emacs.git/tree/src/image.c#n601);
i tried to found bitmap bits by using stipple bitmap id but some
functions/macros are only for X11 (e.g x_bitmap_height and
x_bitmap_width).
I would be happy to read any advice or feedback.
I've attached to this email a patch for the work that i've done and some
screenshots for the final results.
Thanks.

I don't follow your question, but on the assumption that you've run into
difficulties with replacing the background and foreground of the pattern
with those of your choosing, perhaps you must set the "text" and
"background" colors of the DC as suggested by the documentation:
A brush created by using a monochrome (1 bit per pixel) bitmap has the
text and background colors of the device context to which it is drawn.
Pixels represented by a 0 bit are drawn with the current text color;
pixels represented by a 1 bit are drawn with the current background
color.
? Manipulating the stipple bitmap directly should not be necessary, not
with these facilities.

Thank you, the stipple implementation now is almost done, now the only
problem is that stipple bitmap is not monochromatic, i could test
using other monochromatic bitmap and it now works as it should work.
I found that it's a problem with this var
https://git.savannah.gnu.org/cgit/emacs.git/tree/src/image.c#n604.
I'm not sure why and how, i'm trying to figure how to "modify" it
(note: i've printed the BITS bitmap with printf and pasted it, and works
well, i'm not sure if it can be a posible solution).

Good news, the stipple implementation is now done, now works using
indent-bars package and other stipples, however there are some
issues that i want to remark
1. Currently it only works for stipple data and not for X Bitmap files,
I don't know where is stored the code for using X Bitmap in stipples.
2. I had to use `w32_create_pixmap_from_bitmap_data` for make it usable,
but it is defined before `image_create_bitmap_from_data`, i had to
copy its code for use it, Is there a problem move that function
before `image_create_bitmap_from_data` ?
3. The bitmap created using the copied code have colors inverted,
I fixed it setting text color to background color and bg to fg color,
I'm not sure how w32_create_pixmap_from_bitmap_data works, as far as
i could see it does some operations to the memory, something that i
don't think i can help so much.
After fixing 1 (and maybe 2), I will only need to format the code (and
maybe rename XFillRectangle function) for send the final patch here.
I'm attaching the work done if you all want to test it.
Thanks.

I don't understand the problem: in C there's no requirement to have a
function defined before it is used. All you need is its prototype to
be defined before the first use.

Maybe I'm missing something, but where is the stipple in the attached
image?

The stipples are the dashes displayed in the leading whitespace of each

Is that how stipple is supposed to look?

It's kind of hard for me to explain, but I think that doesn't mean it's
hard to solve.
In the documentation
(https://www.gnu.org/software/emacs/manual/html_node/elisp/Face-Attributes.html)
specifies that stipples can be a filepath to an X Bitmap file:
The value can be a string; that should be the name of a file containing
external-format X bitmap data. The file is found in the directories
listed in the variable x-bitmap-file-path.
[-- Attachment #2: stipple2.png --]
[-- Type: image/png, Size: 2868 bytes --]
[-- Attachment #3: Type: text/plain, Size: 1827 bytes --]
That is not done yet, currently setting the bitmap as shown below from
the documentation is done and works well:
Alternatively, the value can specify the bitmap directly, with a list of
the form (width height data). Here, width and height specify the size in
pixels, and data is a string containing the raw bits of the bitmap, row
by row. Each row occupies (width + 7) / 8 consecutive bytes in the
string (which should be a unibyte string for best results). This means
that each row always occupies at least one whole byte.

It's now solved, thank you, i forgot that it is possible in C.

The stipples are the color lines.
In case there are any doubt, here is another image showing another 2
stipples with whitespace-mode turned-on:

About this last one, i've forgot that `image_create_bitmap_from_file`
can fix this, in case i can solve it, the only issue will be the bitmap
having the colors inverted.
A more detailed example about that issue:
1111001111 0000110000
1111001111 0000110000
1111001111 0000110000
1111001111 0000110000
1111111111 0000000000
1111001111 0000110000
Expected Result
in Windows, bitmaps uses 1 for bg color and 0 for fg.

Why is it a problem to invert the bits programmatically? We already
do that in w32_create_pixmap_from_bitmap_data (maybe you could reuse
it?).

I'd to use `w32_create_pixmap_from_bitmap_data` for convert the stipple
bitmap to a Windows bitmap but i've noticed it inverts stipple bits.
It's just something that could be confusing in the future specifically
these 2 lines since it's using bc color for the text color and
vice-versa:
+ SetTextColor (hdc, gc->background);
+ SetBkColor (hdc, gc->foreground);
I tried reuse w32_create_pixmap_from_bitmap_data to obtained bitmap but
it doesn't seem to work, I just hope it's not a problem.
For now the stipple implementation is now complete (as far as i could test),
Now uses xbm files and stipple data.
Here an example using gnus.xbm file:
[-- Attachment #2: gnus_stipple.png --]
[-- Type: image/png, Size: 67226 bytes --]
[-- Attachment #3: Type: text/plain, Size: 85 bytes --]
I would like if someone else can test it for see if there are any
issues.
Thanks.

I've sent the final patch to the bug tracker (bug#71159),
For now i didn't have any problem with the implementation so i think
it's now ready.
One last thing i still wondering is the use of these lines
(https://git.savannah.gnu.org/cgit/emacs.git/tree/src/w32term.c#n1673):

Can we fix this before installing, please? If there are problems with
inverting the colors that you are unsure how to fix, please describe
those problems in detail, so that others could provide advice or code.
Finally, this change needs a NEWS entry, in the "Changes in Emacs 30.1
on Non-Free Operating Systems" section.

Please suggest how to test this.

Severity: wishlist
While we're at it: it would be great if stipples would work on macOS as
well; see bug#70712.

You're not replying to the bug tracker, are you? Besides, how can this
be consigned to a wishlist with any propriety when the implementation is
essentially complete?

Upps, sorry, I managed to paste the wrong piece into this message: It
wasn't meant for the tracker, just a mistake.

It was already removed from the patch that i sent to bug-gnu-emacs
(bug#71159).
I'm wondering if the patch must be here or to the bug tracker, if
should it be sent here i think bug#71159 can be closed.

I would like fix it, but I don't have a clear answer as to why this
problem happens, I just left the notice there as a temp solution in case
someone comes up with a better solution.
I could see that BitBlt maybe can fix this (I've had problems for test
it).
Also I don't think w32_create_pixmap_from_bitmap_data cause this
problem, as far as i could see it's a problem with the bitmap data
image_create_bitmap_from_data (struct frame *f, char *bits,
^^^^
(as example this function)
One solution that i was thinking is using a kind of inverse-video for
make it use fg as bg and vice-versa but I'm not sure how.
Also I was thinking in modifying bitmap data with something like this,
but i don't have idea how:
for (i = 0; i < height; i++)
{
-- Invert bitmap data--
for (j = 0; j < w1; j++)
{
-- Invert bitmap data--
}
}

Done.

> Please suggest how to test this.
Sure, after apply patch and build Emacs, i open runemacs.exe with -Q,
inside the scratch-buffer i paste these code snippets and eval them:
(let* ((w (window-font-width))
(stipple `(,w 1 ,(apply #'unibyte-string
(append (make-list (1- (/ (+ w 7) 8)) ?\0)
'(1))))))
(insert "\n" (propertize (concat (make-string 15 ?\s)
"THIS IS A TEST"
(make-string 15 ?\s))
'face `(:background "red" :foreground "blue" :stipple ,stipple))))
The first makes a stipple with blue lines with a red background.
(let ((str "foobar"))
(make-face 'foo)
(set-face-stipple 'foo (list 2 2 (string 1 2)))
(put-text-property 0 3 'face 'foo str)
(insert str))
This one makes a chess board-like stipple.
font-lock-mode must be disabled for make this work.
Also i use this for test xbm files, in my case i use gnus.xbm file from
etc/images/gnus/:
(set-face-attribute 'region nil :stipple "path/to/xbm/file")
This set a stipple attribute to region face.

The documentation for CreatePatternBrush[1] clearly documents the behavior:
[1]: https://learn.microsoft.com/en-us/windows/win32/api/wingdi/nf-wingdi-createpatternbrush
A brush created by using a monochrome (1 bit per pixel) bitmap
has the text and background colors
of the device context to which it is drawn.
Pixels represented by a 0 bit are drawn with the current text color;
pixels represented by a 1 bit are drawn
with the current background color.
If swapping the background and foreground colors to account for that
mapping is not satisfactory for you, you could invert the bitmap
before creating the brush.
The steps to do that would be, if I have not completely forgotten the GDI API:
1. Use CreateCompatibleDC to create a memory DC.
2. Select the stipple bitmap into this memory DC using SelectObject.
3. Call InvertRect on that DC, passing (0, 0)–(w, h) as the target rectangle.
4. DeleteDC the memory DC.
You should be able to do that once after converting from Emacs format.

Thank you for the advises.
Can you explain why use (0, 0)-(w, h) instead the defined RECT from the
code please?
Here is the current function code with the advises applied (except the
third step that i had to use a defined RECT), but it doesn't seems work
neither, i don't know if i did something wrong when applying the steps:
--8<---------------cut here---------------start------------->8---
static void
w32_fill_stipple_pattern (HDC hdc, struct glyph_string *s, Emacs_GC *gc,
int x, int y, unsigned int width, unsigned int height)
{
SetTextColor (hdc, gc->foreground);
SetBkColor (hdc, gc->background);
RECT r;
r.left = x;
r.top = y;
r.right = x + width;
r.bottom = y + height;
Emacs_Pixmap bm;
bm = FRAME_DISPLAY_INFO (s->f)->bitmaps[s->face->stipple - 1].stipple;
HDC comp_dc = CreateCompatibleDC(hdc);
SelectObject (comp_dc, bm);
InvertRect (comp_dc, &r);
HBRUSH hb = CreatePatternBrush (bm);
FillRect (hdc, &r, hb);
DeleteObject (hb);
DeleteDC(comp_dc);
}
--8<---------------cut here---------------end--------------->8---
Also i'm wondering if BitBlt can be another solution too.

RECT from the code indicates the coordinates where you’re drawing the
stipple. I’m suggesting you invert the stipple bitmap once after
creation so that it could be used without further modifications on
each draw. In this case you need to act on the stipple bitmap
coordinates.

Two things:
1. you invert a RECT defined by coordinates where you draw the
stipple, and that is most likely outside the bounds of the stipple
bitmap;
2. you’re doing it on each draw of this stipple rather than once, so
if you fix the RECT, you’ll be inverting the stipple each time so
odd-numbered draw calls will come out okay but even-numbered draw
calls will again be inverted.

Using BitBlt on the target DC would be trying to fix the misdraw after
the fact. You’d also have to invent a combination of a rop (raster
operation) and whichever auxiliary argument it takes so that it turns
the foreground color into the background color and vice versa.
BitBlt could be used on a memory DC into which the stipple bitmap is
selected, to emulate InvertRect, e.g. passing a rop of DSTINVERT, but
this brings no benefits.

Thanks you, at first it works, but increasing or decreasing text scale
doesn't invert the rect, I'm trying to figure how to calling it once.
Also I'm wondering if it's better invert bitmap pixels before using
_w32_create_pixmap_from_bitmap_data_
Like this:
for (int i = 0; i < (width + 7) / 8; i++)
bits[i] = (~(bits[i]));
stipple = w32_create_pixmap_from_bitmap_data (width, height, bits);
Here is the code:

It's better to send to the bug tracker (and to start the discussion
there in the first place). But sending both here and to the bug
tracker is the absolute worst, so please don't do that in the future.

Please explain the problem in more detail. Above you are talking
about the possible cause and the potential solutions, but do not
describe the problem itself. It's hard to think about solutions
without understanding the problem in detail.

It crashed for me. I needed to make the following changes in
image_create_bitmap_from_data:
#ifdef HAVE_NTGUI
Emacs_Pixmap bitmap = CreateBitmap (width, height, dpyinfo->n_planes,
dpyinfo->n_cbits, bits);
instead of using XFRAME(frame) there, since the variable 'frame' was
not initialized, and you have dpyinfo already anyway.
I guess you sent code that was not the final version?

That's too terse. It should say
---
*** Emacs on MS-Windows now supports the :stipple face attribute.
Also, "---" not "+++" since this change does not require any changes
in the manuals.
Thanks.

I'm sorry about that, i thought that emacs-devel was the right place for
this, now i will send the patch to the bug tracker (specifically to
bug#71159 thread)

It's hard to me explain it with details, i will do my best,
AFAIK the problem is with the bitmap data, which have their bits
inverted, Windows monochromatic bitmaps are reversed compared with X,
what I'm trying to do is reverse the bitmap bytes for make they use the
correct faces.
As i could see, this problem has already happened (see:
https://git.savannah.gnu.org/cgit/emacs.git/tree/src/image.c#n5222)
I would like to know how to apply or reuse that little code snippet for
this stipple implementation.

I'm not sure why it crashed you, I've tested it a lot of times and I
didn't have any problem.

I've applied your changes, i will send the patch to the bug tracker when
the stipple problem is solved.
