I don't think fltk provides for automatic scaling of images, so you need to do that "by hand" yourself. The "correct" way to do this is to access the raw image data then apply whatever interpolation and filtering you think is appropriate to resize the image with minimal visual degradation. However, you can use the image copy() methods in fltk to do basic resampling - works OK, but may cause some image degradation. To see how, refer to the pixmap_browser demo in the test folder. However, I see that has never been updated for fltk-2, so you may need to compare with the fltk-1.1 or fltk-1.3 versions to understand what is going on. It is simple enough. > my fltk version is 2.0 Which, as you know, is not widely supported - you would get better support using 1.1 or 1.3, to be honest. Indeed, those variants have working examples of doing exactly what you are asking...
