Hi All, I'm trying to use Canvas.drawBitmap(int[] colors, int offset, int stride, int x, int y, int width, int height, boolean hasAlpha, Paint paint) to draw an integer color array containing an image pixels array in the format of ARGB_8888 (with alpha channel).
This function is provided in SDK 1.0 to draw a color pixel array directly without creating an intermediate Bitmap. However, I found this function does not perform alpha blending at all. The attached picture is the screen shot of my test result. Left screen shot is the correct result if I create a Bitmap from the color array first then draw the created Bitmap. Right screen shot is the wrong result if I draw the color array directly. I noticed in the wrong rendering, all pixels are treated as either completely opaque or completely transparent. if a pixel has a alpha value other than 0xFF or 0x00 (translucent pixel), it will be rendered incorrectly. I hope anyone in Android team can give some suggestions for this issue. I'm currently thinking this is a bug.
