Hi Kyley, Thanks, although I was asking John for an example of his concern. ;-) I've used Graphics32 previously to resize images with Lanczos Kernel resampling etc myself (see the screenshots on http://gloss.ildica.com/ to see what I use it for), so I know how to resize images properly while maintaining quality. I just wanted to see an example of what was bothering John because personally I don't have any problems resizing images either in code or using tools such as Irfanview (I'm a photographer as well, so I know a fair bit about image sharpening etc too). C.

I have used IrfanView and Photofiltre for resizing images, and noticed they tend to alter the edge pixels around an image - I guess it averages the pixel colours on a sharp edge if resizing smaller. This is a problem with images with a background surround - these pixels are not the transparent background colour any more and create a ragged edge noticeable when the image is on a darker background. How do others resize images properly? (Example is the Analogue clock with the image background some are using- over a dark background you may see there are a fewer light pixels around the edge that shouldn't be there) John _______________________________________________ NZ Borland Developers Group - Delphi mailing list Post: delphi@delphi.org.nz Admin: http://delphi.org.nz/mailman/listinfo/delphi Unsubscribe: send an email to delphi-requ...@delphi.org.nz with Subject: unsubscribe -- Kyley Harris Harris Software +64-21-671-821
