I occasionally use doc-view-mode to read pdfs. I have noticed that if
the window is skinnier than the width of the pdf then the width is
shrunk so that it all fits. However, the height is not affected. This
leads to "squished" text which is unreadable.
To see the effect:
1. emacs -Q
2. open a pdf in doc-view-mode
3. type "W" for `doc-view-fit-width-to-window'
4. C-x 3 to split the window
5. You now have a squished picture.
I think it should not scale the width at all (and it did not use to).
It makes zooming in impossible. Especially it should not scale
the width without scaling the height.

I can't reproduce that on a GNU/Linux box. After step 3, the image fits
exactly the width of the emacs window and the height is set correctly to
keep the aspect ratio. After step 4, I have two side-by-side windows,
each showing about the left half of the image, but no squishing.
Have you compiled emacs with ImageMagick support? I guess so, because
else doc-view would fall back to reconversion with any zooming command.
So let's assume you have ImageMagick support, could you please evaluate
;; That's basically what doc-view with ImageMagic does when
;; fitting/zooming
(insert-image
(create-image "/some/image.png"
'imagemagick nil :width 100))
and play a bit with the width parameter? In any case, the image should
keep its original aspect ratio.
,----[ (info "(elisp)ImageMagick Images") ]
| `:width, :height'
| The `:width' and `:height' keywords are used for scaling the
| image. If only one of them is specified, the other one will be
| calculated so as to preserve the aspect ratio. If both are
| specified, aspect ratio may not be preserved.
`----
If you don't have ImageMagick support, could you check if just finding
some png image with image-mode and then splitting has the same squish
effect?
Bye,
Tassilo

Perhaps it's a NextStep only problem.

I'm pretty sure I don't have it with ImageMagick support. The above gives me an error, and the configure logs confirm this.

I also see the same problem with a jpeg in image mode. I should have checked that first, sorry. Of course, I can't scale the image, but the squishing definitely occurs.

Ok, I don't get that effect even when I explicitly don't use the
imagemagick backend. So it really seems to be a NextStep issue. I'll
close this issue then.
Feel free to report it again as a problem with the NS port.
Bye,

This seems unnecessary to me, so I'm reopening this.
It can be retitled if you feel Docview is unfairly victimised by the
subject.

Hello.
This has been fixed in the trunk.

I think I forgot to say thanks. I appreciate all your work on the NS port.
