It seems there is something wrong with alpha channel reading Image1.Picture.Bitmap, after recent BGRA update. Use this instead: procedure Tf_planetinfo.NAV_Coloring(col: TColor; bmp:TBGRABitmap); ... // if p^ <> black then if (p^.red <> 0) or (p^.green <> 0) or (p^.blue <> 0) then p^ := coln; You may as well move image from Image1.Picture to a file and load it from, instead. Then you may remove Image1 completely from lfm. |

This look related to ColorToBGRA transparency setting, maybe the default change with last version? Just forcing transparency work: https://sourceforge.net/p/skychart/code/3628/ |

This will certainly change in next revision of BGRA, because it is fundamental bug anyway. With alpha channel, correct values are: 0 - Completely transparent 255- Completely opaque That means converting plain 24-bit image to 32-bit should take value 255, not 0, as after this BGRA update is performed. AFAICS, this is the problem in BGRADefaultBitmap: constructor Create(ABitmap: TBitmap; AUseTransparent: boolean = true); override; Then is perhaps better the suggested way, since speed is not critical as temp images are created with form creation and they are quite small. |

OK, probably better this way as we not need transparency. I also remove the useless outer loop and commented code, same for NAV_Disable() https://sourceforge.net/p/skychart/code/3629/ |
