Alpha blending with drawBitmap() and drawBitmap2() - Alpha channel just 1 Bit depth?

Hi,

it seems to me that Alpha blending with bitmaps doesn't work as expected. If I use a bitmap as background and draw (using drawBitmap() and drawBitmap2()) another bitmap with 8-bit Alpha channel on top, transparency only has two levels: fully transparent and fully opaque. This happens in the simulator with all modern AMOLED devices and in reality on my Epix2. Drawing native (setStroke() + fillXxxx()) blends perfectly fine with smooth fades to transparency.

Is there a way to setup bitmaps to do blending as expected, or is this a limitation / bug?

Best,

Holger
