    TBGL-FontFromFile?

    Would there be a possibility to load .ttf-fonts from a file without to have them installed, so they can be used in TBGL?
    Or could TB(GL) install such font temporary - just for the duration of script-execution somehow - maybe could have to "clean-up" manually after TBGL-window is destroyed?

    Perhaps create some small Font-Module that can be included through Uses "Font" so both - UI and TBGL - could work with temporary installed fonts?

    Would only need two or three functions:

    String FontName = Font_Install(Filename)
    If Font_Exists(FontName ) Then Font_Uninstall(FontName)

    ... I know this could be helpful - but I don't get it together...

    Hi Rene,

    interesting request. For which reason would you hesitate to install the font first?
    If you have license for it, you can use it, if you don't, even this use would be illegal

    There are loads of free fonts available and I could create my own.
    And the reason is: Not everyone has the same fonts installed I have- for a game or gui I might need a special/monospaced one that none else has installed by default. If user has to fear some copyright-problem so it's his own fault: Would be the same if I would use TBGL-FontCreator on some by copyright law protected font and ship it with my app - I would be responsible.

    I see,

    most programs solve this by having installer - for example innoSetup is free and works good.
    But I will think more about this, ability to drop user EXE without need for installing is comfortable.

    Hi Rene,

    something to get you started in the attachement - it shows how to use AddFontResource/RemoveFontResource.
    Maybe it could be added as native Font_Add, Font_Remove...

    I am leaving outside to get lost in the woods for the rest of the day, my eyes are burning after PC weekend

    That works! But now I need to retrieve the Fonts name somehow - probably have to use UI-Function Font_List before and after install to compare and find out the new fonts name. I'm just not happy with that because means have to use "UI" just for this. Maybe is possible adapt Font_List-function from UI or create another? Or is there a way to retrieve the fonts name out of the file somehow? The modified script below uses UI anyway...(above attached version did not really uninstall since hFont was not static)... but what if use TBGL only?

    Uses "UI"

      $FontFile = APP_SourcePath + "scrgunny\scrgunny.ttf"

    I think we could build together font specific include file - this is nothing performance intensive, so module would not bring anything new.
    I will check how to retrieve font name from TTF...

    Hi Rene,

    this seems to work - font must be installed, but it is still better than going through the list:
    Uses "Console"
    
    Declare Function AddFontResource Lib "GDI32.DLL" Alias "AddFontResourceA" (ByRef lpszFilename As Asciiz) As Long  
    Declare Function RemoveFontResource Lib "GDI32.DLL" Alias "RemoveFontResourceA" (ByRef lpFileName As Asciiz) As Long
    
    Declare Function GetFontResourceInfo Lib "GDI32.DLL" Alias "GetFontResourceInfoW"(ByVal lpszFilename As DWord, ' -- font file Name
                                                                                      ByRef cbBuffer     As DWord,  ' -- size of buffer for resouce information
                                                                                      ByVal lpBuffer     As DWord,  ' -- buffer for returned resouce information
                                                                                      ByVal dwQueryType  As DWord ) As Long   ' -- resouce information query type
                  
    Function TBMain()   
      Dim azFontFile As Asciiz * 256 
      azFontFile = APP_SourcePath + "scrgunny\" +  "scrgunny.ttf" 
      Dim wFontFile As String = Ucode$(azFontFile)
      Dim wBuffer As String = Repeat$(512, " ")
      
      AddFontResource(azFontFile)
      
      DWord sizeOfWBuffer = Len(wBuffer)
      PrintL "Testing file: " + azFontFile
      PrintL GetFontResourceInfo(StrPtr(wFontFile), sizeOfWBuffer, StrPtr(wBuffer), 1)
      PrintL "Name is: " + Acode$(wBuffer), Len(wBuffer)
      
      
      RemoveFontResource(azFontFile)
      WaitKey

    OK. It works. I added a little to get the real string out of it- so truncate all $NUL-Chars
    Uses "Console"
     
    Declare Function AddFontResource Lib "GDI32.DLL" Alias "AddFontResourceA" (ByRef lpszFilename As Asciiz) As Long

    Declare Function GetFontResourceInfo Lib "GDI32.DLL" Alias "GetFontResourceInfoW"(ByVal lpszFilename As DWord, ' -- font file Name
                                                                                      ByRef cbBuffer     As DWord,  ' -- size of buffer for resouce information

                                                                                      ByVal dwQueryType  As DWord ) As Long   ' -- resouce information query type
                   
    Function TBMain()   
      Dim azFontFile As Asciiz * 256 
      azFontFile = APP_SourcePath + "scrgunny\" +  "scrgunny.ttf" 
      Dim wFontFile As String = Ucode$(azFontFile)

      AddFontResource(azFontFile)
       
      DWord sizeOfWBuffer = 512 ' Len(wBuffer)
      PrintL "Testing file: " + azFontFile
      If GetFontResourceInfo(StrPtr(wFontFile), sizeOfWBuffer, StrPtr(wBuffer), 1) Then

    I had to change a little- somehow the above did not really install - probably string-types mixed up. So this morning I made some slightly different - mixed of all we already got. 3 win-functions declared - and 2 tB-functions made from it - Font_Install + Font_Uninstall. Second is just alias.

    This time test in TBGL
    Uses "TBGL"

    Because only temporary installs user-fonts the Uninstall-Procedure would need for full functionality some method to find out the filename of a font by its font-name. But I'm not in need of this right now. All the above serves to be temporarily used. I rechecked just by opening some new RTF-Doc while running it and thereafter. Install/Uninstall really works - but what will happen if the font is already installed on the users system? - I just ask myself... I hope won't be a problem since the font we install/uninstall is on a different path - so we don't uninstall the wrong one.
