Displaying images on the screen has nothing to do with image-handling library.
That's what I would expect from image handling library (just few examples): - Changing image brightness, - adjusting gamma levels, - changing color modes, - converting from CMYK to YCbCr, - scaling using various interpolation methods, - rotating. - provide an access method for OTHERs who want to display the image on the screen (or somewhere else), it's not even the UI (or the printer) that displays this image - it is something in between. - etc.. - Image I/O in various formats (tiff,jpg,png) is just an extra bonus here.
What about image *processing* ? Things like
- sharpening, smoothing, thresholding, dilation, erosion - compression, FFTs, wavelets - feature detection, segregation - morphing
I have only quickly skimmed through GIL docs, so I don't know if GIL provides *processing* algorithms. It would be nice to have that. But maybe due to the fact the the number of such *processing* methods is almost infinite (just look at how many plugins GIMP has) I rather expect this library to provide an easy interface to implement any (and all) of those that you mentioned above. -- Janek Kozicki |
