I must note that I'm not too familiar with the Java2D API, but while working on a little project of mine (which involves reading packed RGB values directly from a Raster's DataBuffer), I noticed the following behavior when trying to convert from BufferedImages that use the sRGB color space to ones that use linear RGB.
Assuming [i]sRGBImg[/i] uses the sRGB color space and [i]linearImg[/i] uses a linear RGB space, the following methods of transferring image data from sRGBImg to linearImg deliver different results: Method1: Graphics2D g = linearImg.createGraphics(); g.drawImage(sRGBImg, 0, 0, null); Method2: new ColorConvertOp(null).filter(sRGBImg, linearImg); I thought, that drawImg would perform color space conversion if the source image was in a different color space that whatever one is drawing to. However, it appears that no color space conversion is performed with method 1, whereas color values are converted when performing method 2. As a sidenote, the image created with method 1 renders correctly when used in some component's painting code, whereas the one created with method 2 does not (probably because transformation to the target color space is ignored when painting as well). BTW: RenderingHints set for the Graphics2D / the ColorConvertOp do not appear to make any difference. Just curious: Is this the expected behavior of Graphics2D#drawImage? If so, is this guaranteed somewhere so that I can rely on it for future endeavors?
