I'm learning Android by making an app where a rocket scoots about on the screen. So far, so good, and the LunarLander sample code has been a goldmine of useful information.
Here's the problem. When I rotate my rocket (a PNG image with transparency), it occasionally leaves little pixel "droppings" on the background. If I use the rocket from LunarLander, no problem. So, that rules out the code, so I must have something odd about my image. It started as a 24-bit PNG image, but I scaled it down to an 8-bit PNG after studying the LunderLander image file. I still have the same problem, though. So, what's wrong? Is the a special setting I should use in a program that saves PNGs? Other info is: 1) My rocket is a lot longer than it is wide, unlike the lunar lander image. 2) The original image was made with anti-aliasing on. Could that have had an effect when I turned the background color to white? 3) The code basically is (same as in LunarLander): canvas.save(); canvas.rotate((float)mHeading, (float) mX, (float) mY); mShipImage.setBounds(xLeft, yTop, xLeft+mShipWidth, yTop+mShipHeight); mShipImage.draw(); invalidate(xLeft-20, yTop-20, xLeft+mShipWidth+20, yTop+mShipHeight +20); canvas.restore(); Any suggestions/solutions welcome. All that's left to getting this thing running is cleaning up the image redraw. ---Tom --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
