RGBA Sprites vs 16Bit Screens

[nco2k]

i know this is not a real bug, since rgba sprites are meant to be displayed on 32bit screens, but it would be nice, if they would look the same on every subsystem and perhaps there is even a workaround, to make it actually work like on open gl.

Code: Select all

UsePNGImageDecoder()
If InitKeyboard() And InitSprite() And InitSprite3D() And ExamineDesktops() And OpenScreen(DesktopWidth(0), DesktopHeight(0), 16, "Test")
  If LoadSprite(0, "C:\redrose.png", #PB_Sprite_Texture | #PB_Sprite_AlphaBlending) And CreateSprite3D(0, 0)
    Repeat
      ClearScreen(RGB(128, 128, 128))
      If Start3D()
        DisplaySprite3D(0, 10, 10)
        Stop3D()
      EndIf
      FlipBuffers()
      ExamineKeyboard()
    Until KeyboardPushed(#PB_Key_Escape)
  EndIf
EndIf : End
