Hello, why are the fonts used in the project not applied to the generated svg file when we use SvgVectorOutput?
What should be done to solve this problem?

Please provide a working example which shows the problem.

Hi
If you are a windows user
The vector lib deals only with the installed fonts

For example, when I run the following code:

Code: Select all

 If OpenWindow(0, 0, 0, 500, 250, "VectorDrawing", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
    CanvasGadget(0, 0, 0, 500, 250)
    LoadFont(0, "tahoma", 20, #PB_Font_Italic)
    
    If StartVectorDrawing(SvgVectorOutput("nt.svg",500,250))
    
      VectorFont(FontID(0), 125)
      Text$ = "Sample"
      
      ; draw text
      MovePathCursor(25, 25)
      DrawVectorText(Text$)
      
      ; draw logical bounding box
      AddPathBox(25, 25, VectorTextWidth(Text$), VectorTextHeight(Text$))
      VectorSourceColor(RGBA(0, 0, 255, 255))
      DashPath(2, 10)

      ; draw visible bounding box
      AddPathBox(25 + VectorTextWidth(Text$, #PB_VectorText_Visible|#PB_VectorText_Offset), 
                 25 + VectorTextHeight(Text$, #PB_VectorText_Visible|#PB_VectorText_Offset), 
                 VectorTextWidth(Text$, #PB_VectorText_Visible), 
                 VectorTextHeight(Text$, #PB_VectorText_Visible))
      VectorSourceColor(RGBA(255, 0, 0, 255))
      DashPath(2, 10)        
      
      ; draw baseline
      MovePathCursor(25, 25 + VectorTextHeight(Text$, #PB_VectorText_Baseline))
      AddPathLine(VectorTextWidth(Text$), 0, #PB_Path_Relative)
      VectorSourceColor(RGBA(0, 255, 0, 255))
      DashPath(2, 10)                    

      StopVectorDrawing()
    EndIf
    
    Repeat
      Event = WaitWindowEvent()
    Until Event = #PB_Event_CloseWindow
  EndIf

I get the following result, which is not correct.
When I manually change font-family="t" to font-family="tahoma", the result is correct.

Code: Select all

This looks like a bug.
Only "t" is wrong.

A moderator should move this in the bug section for investigation.

Strange, the code runs fine here (on Windows and MacOS, PB 6.21)
The generated .svg has the full font name (on MacOS, for a reason i don't understand, tahoma is replaced by system Font, but if you try Arial or Courier, it works fine)

I'm trying it on Windows and I'm having this problem for all fonts.

OS Window
Works with PB v6.12 but not since v6.20.
So a bug
