Have a couple of pdf files that have some bitmap signatures on the bottom of page, need to add mine there and save as pdf again... the problem I have is that those existing signatures are re-compressed and looks bad on export. They are 1 bit bitmaps I think... So, I want to keep or skip compression for those 2 images and also add mine -no problem there- Any advice on this..? some other tool maybe?
Bit depth is one thing, actual size is another. I'd see if I could autotrace them or make greater bit-depth copies. Alt-B makes a 32bit bitmap copy of any Inkscape object, at a size (dpi) set in the preferences.
ok thanks tyler for answering, need to think a bit about that... what helped was to save pages as plain svg files, then loaded them in my browser -vivaldi- and used it's 'print to pdf' feature... worked great for single pages -but then needed some other tool to merge pages-
printing through the browser worked, then tried also Alt+B at 300dpi, ungrouping and removing clipping masks, changing rendering settings, couldn't find a good solution... I think browser uses lossy compression too, but it's not so agressive on this b/w images

On Windows I use PDFill tools (free) for compiling pages, watermarking etc. No experience with tools on other OSs.
thanks, solved it already, just wanted to report what I found...
