If your "better" meant "faster", you might like to take a look at this: https://jai-core.dev.java.net/source/browse/jai-core/src/share/classes/com/sun/media/jai/opimage/AddOpImage.java?rev=1.1&view=markup under computeRectByte() // // The next two lines are a fast way to do // an add with saturation on U8 elements. // It eliminates the need to do clamping. // sum = (s1[s1PixelOffset]&0xFF) + (s2[s2PixelOffset]&0xFF); d[dPixelOffset] = (byte)((((sum<<23) >> 31) | sum) & 0xFF); HTH, -James [Message sent by forum member 'jxc' (jxc)] http://forums.java.net/jive/thread.jspa?messageID=230881 =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA2D-INTEREST".
