Assume the original image is 400x400 pixels. Whem I zoom in the map, the image is stretched. The problem is that the stretch effect is 'blurry'. How can I avoid this blurry effect and instruct openlayers to apply a normal 'raw' stretch on the image? Is there some options somewhere? When I say blurry, I mean this:<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>(see fig1.pngf in attachments)<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>The image above demonstrate the concept. I have a 400x400 pixels image. The image is formed by 4 sub squares 200x200 pixels each. Top left square is blue, top right is green, bottom left is yellow and bottom right is red. When I draw this image as an image layer in openlayers and I zoom the map, the center of the image gets blurry and the four colors are blended. Is there a way to avoid this blur effect and have a 'raw' stretch?
