Thank you Eugene for your reply.
I think the solution is the one proposed by Thomas:
You defintely have a point but I think it can be solved in various ways. Inspired by you I would suggest that InDesign got a new layer option so it became possible to just choose a layer for rasterization BUT with a popup-dialogue where you could check/uncheck different “types of vectors”..."
Unfortunately I didn't understand how to do this.
Could you please explain this trick?
Unfortunately, Thomas was just suggesting an idea that could be possible to implement to InDesign.
The idea is still just an idea.
You'd have to convert all the images to JPG or PNG and manually update the links.
Best to do this in a new file that is a copy of the previous.
At the end, you mean that at the moment it is not possible to mantain only one indesign file, choosing the option, time by time, to export or the fully vector version or just the bitmap version (manteing only the text as vector) ?
You could do it with layers - but it's rather complex way to work and to ensure you have the correct layers turned on.
Plus somtimes you want background images, and foreground images and images inbteween background and foreground.
At the moment - InDesign will export to PDF and use the linked files as the source of what is inserted into the PDF.
Think of PDF as a wrapper for all your content.
If it's an EPS in your layout - it's a vector in the PDF.
I don't know of a way to do what you want - except manually doing it.
I have not tested this, but it might be possible if all pages have transparency that interacts with the images. You could then use a custom flattener setting that is set to 100% rasters, but I'm not sure what it would do to the type. You could test on a single page file.
