Package: tetex-bin

Severity: normal
Greetings,
I'm trying to make a PDF of a bunch of 1024x768 .png images, so I used
pdflatex with \pdfimageresolution 180 to fit two images to a page.
Works great.
So then I decided to put one image to a page, rotated 90 degrees. But
with 768x1024 .png images (rotated using the GIMP Image | Transforms |
Rotate | 270 degrees), \pdfimageresolution is totally ignored, the
images spill way over the edges of the page because they're put in at 72
dpi.
If I mix 1024x768 and 768x1024 images in a document, the former come out
just fine at 180 (or whatever) dpi, the latter at 72.
I guess this is an upstream bug. In any case, thank you for maintaining
some terrific tetex packages!
Zeen,

D'oh! GIMP enables "Save resolution" by default when saving a PNG file.
Disabling this (have to do it in each GIMP run) fixed the problem,
turning off the internal resolution in the PNG file so it would be set
by \pdfimageresolution.
Sorry to bother you, this bug is closed.
