Stamp replace images

[Frolanta]

I’m using your tool to stamp multiple pdf into one big pdf at specific coordinates. My issue is sometime there are images embedded on those files and is seems there is a problem with that. After the stamp all images (on the big pdf) are replaced with the image of the stamp.

Is guess that’s because they have the same name (Im0) and after the stamp there are renamed aIm0

./cpdf -image-resolution 30000 out-12.pdf 1, /aIm0, 498, 1033, 200.902220, 200.902220 1, /aIm0, 498, 1033, 200.902220, 200.902220 1, /aIm0, 498, 1033, 197.830693, 197.830693 1, /aIm0, 498, 1033, 85.698914, 244.084083 1, /aIm0, 498, 1033, 206.657406, 206.657406 1, /aIm0, 498, 1033, 204.113852, 204.113852 1, /aIm0, 498, 1033, 204.113852, 204.113852

There is an exemple: Big file:

Stamp:

Command: ./cpdf -stamp-on rotated-fixed-11.pdf -relative-to-cropbox -pos-left "311.8110236219 680.3149606295999" out-11.pdf -o out-12.pdf

Result: (The one that are not replaced do not use images)

This is what I get when inspecting the file with acrobat:

I can edit image(154) with photoshop and it confirm all the images have been replaced by the one on the stamp.

I’m using the OSX binary and all my pdf are version 1.5

Am I missing something or ?

files used: out-11.pdf rotated-fixed-11.pdf

I think this should be fixable. But I will need to see the start of the process, where cpdf first gets involved. It looks like out-11.pdf has already been processed by cpdf.

Can you provide original files which have not been processed by cpdf, and exhibit a command, or series of commands, which leads to a file containing duplicate image names?

[Frolanta]

Yes you are right, there has been multiple stamps and rotations performed on out-11.pdf Here a complete process with originals files.

./cpdf -rotate 270 1.pdf AND -upright -o rotated-0.pdf
./cpdf -stamp-on rotated-0.pdf -relative-to-cropbox -pos-left "992.1259842515 0" out-0.pdf -o out-1.pdf

./cpdf -rotate 270 2.pdf AND -upright -o rotated-1.pdf
./cpdf -stamp-on rotated-1.pdf -relative-to-cropbox -pos-left "566.929133858 0" out-1.pdf -o out-2.pdf

Files: 1.pdf 2.pdf out-0.pdf

FIxed in trunk camlpdf.

[Frolanta]

Great, when do you think this will be available in cpdf ?

[johnwhitington]

You can compile it from source yourself, by picking the trunk versions of camlpdf and cpdf, or you can wait for the next release in a year or so.

Or, if you're a paying customer, we can provide a binary build straight away.

Working great, thanks.
