PNG-8 and not PNG-24, not sure which you are using, but definitely use PNG-8 or GIF.
In fact, its better to extract in PNG-24 from Flash then you work on the images on photoshop.
And here is a quick trick:
If you wanna blend the sprites border in a better way (without half tones of the background, for example), do the following:
- Export the image in Save for web (CTRL+SHIFT+ALT+S heheeheh its a big shortcut but you can do it with one hand, believe me)
- Choose GIF and on MATE you put BLACK and TRANSPARENT (no color). This will add a solid black border on your sprite, giving you less headache.
- after that, open the image again and convert it to pcx.
If you try to convert right for PCX, you will have some issues with the background colors.
