Hi! I played a bit with palettes PNG and found a strange problem. Did anybody ever encounter this? Any guess on how to fix? Allegro 5.1.9, both DX and OGL - so it is somewhere in the "read" part. LibPng? Thanks, |

For future reference, you can link directly to your attached pictures in the forum! Just put the address in [square brackets]. {"name":"609348","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/3\/c\/3c92532befd312292ade58b83a3f33e6.png","w":635,"h":504,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/3\/c\/3c92532befd312292ade58b83a3f33e6"} {"name":"609349","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/0\/f\/0f1d43c4e1829e141ffc1106af5dfc37.png","w":256,"h":256,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/0\/f\/0f1d43c4e1829e141ffc1106af5dfc37"} Also, what color depth are you running? Sometimes different drivers force different depths, so a Linux machine is 24-bit and a Windows is 32-bit color (that happened to me.) Make sure you're not doing any accidental color conversion by making sure Allegro is set to the desktop depth. -----sig: |

I set no options except for ALLEGRO_DEPTH_SIZE, but removing it does nothing. Actually, nothing I tried in display creation affects the effect. I really suspect this is something about loading PNG, not displaying them... |

Yeah, the code that loaded the pngs with a palette and transparency was completely broken. This is now fixed in 49b7f67208c7a544e0e4276e17a09459bf4687c0. There really is no good workabout, aside from not using pngs with a palette and transparency. "For in much wisdom is much grief: and he that increases knowledge increases sorrow."-Ecclesiastes 1:18 |
