            Bug ID: 92449
           Summary: pdftohtml ignore png format option and extract
                    inverted jpg images
           Product: poppler
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: pdftohtml
          Assignee: poppler-bugs at lists.freedesktop.org

Hi all,

I use pdftohtml 0.37.0 on Ubuntu.

When I call 
pdftohtml -xml -fmt png
command - some images are extracted as .jpg (all with inverted colors) and some
as .png (all with normal colors).

When I call
pdfimages -all test.pdf test
command - I get same result for images (inverted .jpg and normal .png).

But when I call
pdfimages -png test.pdf test
command - I get only .png images and all of it has normal colors.

Questions:
1. Is it possible to convert pdf to html/xml using pdftohtml utility with
export all images to .png? Or at least to have non-inverted .jpg images?
Because now I need to call 2 different commands for same pdf page to get
correct result? It seems that `-fmt` option doesn't work
2. if using `pdfimages -all test.pdf test` command first image is extracted as
.jpg and second as .png - does it mean that first image is actually stored in
JPG format in pdf? and same for second image?
3. is it ok, if exported via `pdftohtml -xml` image has one resolution
(width-height), but another inside generated xml? for example, file has
width=145, height=145, but inside xml it has width=105, height=105?

PS: I can attach pdf file if needed

Thanks in advance,
