Finally updated my Silh Studio File Formats Cheat Sheet for V3. Update: The image below is no longer current. Click here for a current printable PDF.
The changes from version 2: Macs lost the ability to open .ai files, Mac basic users lost the abililty to open .pdf files. Win DE users gained the ability to open PDFs, and all DE users can take full advantage of vector PDFs as of version 3.3. BE added new vector options.
I’ve also prepared a new chart just to help you understand how to handle a PDF depending on its content and what version of Silhouette Studio you have.
To determine if a PDF has vector or bitmap content, zoom in to at least 800% and if the lines are still crisp, it is a vector. If the lines are blurry or pixellated, it is a bitmap. If you need help understanding the difference between vectors and bitmaps in general, this video should help.
