I've tested the code (see below) on 'Concept s60 SDK 0.2b' and 'Symbian SDK 1.0' emulators. The code fragment draws 3 images on the white screen, but in 'concept' emulator they seem to be all different, and in 'symbian' one -- they're the same, but with fake alpha-blitting support. Unfortunately, I have no possibility to test in on the real s60 device (I'm targeting 7650)...

a) So, the question is -- what's wrong?
b) Which emulator is more close to the real device and what will be shown on 7650?
c) How to make it all work on 'concept' emulator?
d) Why the 'symbian' emulator is so slow comparing to 'concept' one? which of them gives the performance more close to 7650?

The 1st image is shown in a right way on 'concept' emulator (using 'brute force' loading and draw functions).
The 2nd image is non-transparent at all.
The 3rd one seems to contain wrong pixel data (getPixels() doen't work?)

---------------------- beginning code -----------------------------------
protected void paint (Graphics g)
{
int width = 0, height = 0, format = DirectGraphics.TYPE_USHORT_4444_ARGB;
short [] pixels = null;
Image img = null, mi = null;
try {
// (creating 1st)
img = Image.createImage("/test.png");
width = img.getWidth();
height = img.getHeight();
// (creating 2nd)
mi = DirectUtils.createImage(width, height, 0);
DirectGraphics dg = DirectUtils.getDirectGraphics(mi.getGraphics());
dg.drawImage(img, 0, 0, Graphics.TOP | Graphics.LEFT, 0);
// (creating 3rd)
pixels = new short [width * height + 1];
dg.getPixels(pixels, 0, width, 0, 0, width, height, format);
} catch (Exception e) {}

DirectGraphics fcdg = DirectUtils.getDirectGraphics(g);
g.setColor(0xffffffff);
g.fillRect(0, 0, getWidth(), getHeight());

// (drawing 1st)
fcdg.drawImage(img, 0, 10, Graphics.TOP | Graphics.LEFT, 0);
// (drawing 2nd)
fcdg.drawImage(mi, 30, 10, Graphics.TOP | Graphics.LEFT, 0);
// (drawing 3rd)
fcdg.drawPixels(pixels, true, 0, width, 60, 10, width, height, 0, format);
}
---------------------- the end -----------------------------------
