Hello,
I read a image in my application and scale it on an existing thumbnail-image
with the following code:
Image image = new Image(null, 50, 50);
ImageData fileImageData = new ImageData(filename);
Image fileImage = new Image(null, fileImageData);
GC gc = new GC(image);
Rectangle r = fileImage.getBounds();
gc.drawImage(fileImage,0,0,r.width,fileImage.height,0,0,49,4 9);
gc.dispose();
fileImage.dispose();
If I process an 60 kByte-JPG-image my application need around 3 seconds to
execute the code.
If I process an 3 kByte-GIF-image my application need around 0,4 seconds to
execute the code.
Is there any possibility to increase the speed?
Bye Stefan

Check out Eclipse bug 53443. It is a request for native image loading.
