I would think they would have to be imported as PNGs instead of TIFFs. I don’t see any setting in the Export menu to convert imported images into a different format…unless the entire graphic is converted. Many experts here so hope you find a better answer.
Actually, no problems. The issue was caused by copy/pasting the images in. The user was expecting the pasted image to keep the original file format, but the pasting process converts to TIFF.
However, it would be a nice-to-have if there was some control over the output image format as then users who put in TIFFs could still get web-viewable SVGs if the images were transformed to PNGs.
Also, while I’m thinking of SVGs, having images encoded as data URIs in SVG export would also be a very handy option. This would mean the SVG would be a single file containing all the linked images - no need to save a folder full of files.
I did not realize that. Probably why the file size grows so fast when images are dropped on it. I use PDF (which are considered vector files) snippets in my drawings and now I know why they loose their clarity when resized.
