Posted - Mar 16 2012 : 04:19:05 I have looked at the thumbnail demo and tried to adapt it to generate a square thumbnail! Is there anyway that I can shrink and crop the image to generate a 160x160 thumbnail instead of the one in the demo that maintains the aspect ratio?

Thanks for the advice that snippet works fine.

Images without maintained AR tend to look odd, so you may prefer to resize and then crop as follows:
If the source image is portrait shaped call:
ImageEnProc.Resample(160, -1, rfLanczos3)
ELSE { Landscape }
ImageEnProc.Resample(-1, 160, rfLanczos3);
Then resize the image cropping off the outlying pixels:
Posted - Mar 16 2012 : 10:58:37 Images aspect ratio cannot be disabled. You have to put a 160x160 image (or resize/crop already added images). For example this code resamples all images to 160x160:
var
i:integer;
begin
for i:=0 to ImageEnMView1.ImageCount-1 do
begin
ImageEnMView1.SelectedImage := i;
ImageEnMView1.Proc.Resample(160, 160);
end;
end;
