Hi Folks,
What would be the best way to create a Bitmap from a raw pixel array?
I need to display an image whose source is an array of bytes
describing the pixels (RGB or grayscale).
I tried to use createBitmap() but in that case I need to create an int
array of colors from my byte array so that takes lots of memory for no
specific need. Specially for grayscale images.
=======================================================================
// Set bitmap array from decoded array
int i, j;
int dataSize = width*height;
int[] pixelIntData = new int[dataSize];
for( i=0; i<dataSize; i++ ) {
pixelIntData[i] = Color.rgb((int)decodedByteArray[i],
(int)decodedByteArray[i], (int)decodedByteArray[i]);
}
Bitmap myBitmap = Bitmap.createBitmap(pixelIntData, width, height,
Bitmap.Config.ARGB_8888);
========================================================================
Also I do not have the right color doing so. I don't know how to check
what is returned by the Color() function.
Any help would be greatly appreciated,
Thanks
STN
