gimp saving as pdf

Hi


When I try to  save an image as a portable document format (pdf) in gimp, it asks if i would like to convert bitmaps to vector graphics. What does it mean? And what are the consequences of not checking it on when saving?

thanks

Here's a quick explanation. In vector graphics, graphical elements are represented as mathematical expressions, thereby creating a resolution-independent format, meaning they can be scaled without loss of resolution. In bitmap graphics (also called raster graphics), graphical elements are represented as pixels, and cannot be scaled without resolution issues.

GIMP is primarily a bitmap/raster graphics program, but it does have some basic support for vector graphics, such as the ability to convert bitmaps to vector graphics where possible (as it says in the Export dialog for PDF that you mentioned).

If you'd like to learn more, Google is your friend, such as the Wikipedia articles on both topics:
https://en.wikipedia.org/wiki/Raster_graphics
https://en.wikipedia.org/wiki/Vector_graphics

Those articles will also help you to understand the consequences of not checking vector graphics when doing the export in GIMP. Regards, Joe
