Hello piplz,
A bitmap 128x128 ARGB8 is loaded. Only the alpha channel is needed as the
opaqueness is used to draw the desired color. Using the original bitmap with
a PorterDuffColorFilter and Mode.SRC_IN functions properly.
The next step was to extract the alpha channel to save some memory. The
extracting seems to function properly, but the actual drawing in Canvas
results in a SIGSEGV.
Info: all drawing happens in another thread.
Drawing:
void android.graphics.Canvas.drawBitmap(Bitmap bitmap, Rect src, RectF dst,
Paint paint)
Alpha extracting alternative 1:
Bitmap android.graphics.Bitmap.copy(Config config, boolean isMutable)
... with Config.ALPHA_8, true
Alpha extracting alternative 2:
Bitmap android.graphics.Bitmap.extractAlpha()
Will try: doing the same pre-extracting and then drawing with ES 2.0.
Here logcat output:
