RGB/BGR differences between Android and iOS

[whispercomputersolutions]

First off, I Love this project. Allows me to add ellipses, rectangles and arrows to photos on mobile devices.

Maybe I'm missing something simple, but it seems I had to do the following in my FMX app.

I chose yellow to draw these layers. But on Android, the red and blue are backwards for the pen color selection, but not on iOS. To correct on Android, I had to conditionally compile and then when setting a pen color in the Draw function I use this function:
function PlatformColor(pColor: TColor32): TColor32; begin {$ifdef Android} Result := RGBtoBGR(pColor); {$else} Result := pColor; {$endif} end;
Next issue: When loading a jpg image stream into a bitmap on Android, the image colors are fine. Bit when loading on iOS the red and blue are swapped. In this case for iOS only, I had to traverse the bitmap image to swap red and blue:
procedure ConvertBitmapToABGR(var ABitmap: TBitmap); var Data: TBitmapData; begin // Map the bitmap memory for read-only access if ABitmap.Map(TMapAccess.Read, Data) then try for var Y := 0 to ABitmap.Height - 1 do begin for var X := 0 to ABitmap.Width - 1 do begin // FMX native 32-bit color (Alpha, Red, Green, Blue depending on platform) var ScanLine := PAlphaColorArray(Data.GetScanline(Y)); ScanLine[X] := RGBtoBGR(ScanLine[X]); end; end; finally ABitmap.Unmap(Data); end; end;

Did I miss something?
