I imported a PDF and saved as a Corel .cdr file.
When I use the crop tool, the image disappears.
I've uploaded the Corel file. Any suggestions?
If you uploaded the .CDR file to the forum, then the upload may have failed.
I don't know that .CDR files are accepted directly. Some users wrap them in a .ZIP file; others put the file somewhere on-line and share a link to it.
Oh well, I exported the CDR file as a PSD image file, then imported the PSD into Corel and the crop tool worked.
