The code is meant to insert 3 bars of equal length, each 1/3 of the window size in pixels. Unexpectedly, the rightmost bar is much shorter than the other two bars. I say "unexpectedly", because the documentation of insert-image (which is used to insert the image by the forms above) states: "If SLICE is =E2=80=98nil=E2=80=99 or omitted the whole image is insert= ed." Yet, even though SLICE is omitted in the forms above, the whole image is apparently not inserted, only a smaller slice is inserted. If possible, I would like to insert the entire image no matter where it appears in the buffer, even if scrolling is necessary to reveal remaining parts. Is there a way to do this? Thank you a lot!
