Does scale to ppi work with InDesign CC2019?
Should do. But the objects shouldn’t use the new CC2019 size and position options that sets their size as part of an object style.
Is there a video or something showing exactly what this does? Do it open the image in another program, resize it and save it? That would be ideal. Ideally saving it with a new name and then importing it.
I haven’t made a video of this one yet, unfortunately.
What it does is resize the image in InDesign – same as if you Ctrl+Shift-dragged a corner of the image – so that it hits a target PPI.
The size of the image on the InDesign page will change so that the image’s “Effective PPI” matches your target PPI.
It does not export the image to Photoshop, modify the resolution, resave, etc., as you describe.
However, I do vaguely recall that there is a script or plugin that does what you’re asking, out there somewhere. Had a quick look but couldn’t find it. If you find it, feel free to post back here with a link!
