LoadFont() never return zero

Hi,
If the font was not loaded successfully, LoadFont() returns nonzero instead of zero.
Code: Select all
If OpenWindow(0, 0, 0, 270, 160, "Loading font...", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
r = LoadFont(1, "", 24)
Debug r
r = LoadFont(#PB_Any, "", 24)
Debug r
r = LoadFont(1, "anything", 24)
Debug r
r = LoadFont(#PB_Any, "anything", 24)
Debug r
r = LoadFont(1, "Arial", 24)
Debug r
r = LoadFont(#PB_Any, "Arial", 24)
Debug r
Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
EndIf

This is documented, it's the way Windows works:
Code: Select all
On Windows the font mapper will always attempt to locate a font. If a font name which does not exist such as: "Tim Now Ronin", is used, then the font mapper will attempt to find the closest match. This will be based upon such criteria as: the font name, the font height, the style and so forth. Therefore, the assumption can not be made that a font will not be loaded, due only to an incorrect font name, size, ect...

Thank you.
I get the same thing under Linux (Lubuntu 16.04.1 LTS, 64-bit)
So, LoadFont() and IsFont() never seem to return zero... Why not !?
I'll take a look at RegisterFontFile() to be sure to have the good Font.
