We have our custom font (ttf) that we want to use in PB application. We don't want to register it globally, the idea is to use it privately just for our application and no other application should see it in the list of available fonts. 

In .Net there is a PrivateFontCollection Class that allow to use a font privately. Is it possible to achieve similar thing in PB?

Thank you,

Yuri

Hi Yuri,

I do it this way:

Declare two local or global external functions:
// GDI32.dll
function long AddFontResourceExW( readonly string as_FontFile, ulong aul_FontCharacteristics, ulong aul_Reserved ) library "GDI32.dll" alias for "AddFontResourceExW"
function boolean RemoveFontResourceExW( readonly string as_FonfFile, ulong aul_FontCharacteristics, ulong aul_Reserved ) library "GDI32.dll" alias for "RemoveFontResourceExW"


Load the font before using with:
public function long of_addfont (readonly string as_fontfile):
long    ll_rc

ll_rc = AddFontResourceExW( as_FontFile, 16 /* FR_PRIVATE 0x10 */ + 32 /* FR_NOT_ENUM 0x20 */, 0 )

return ll_rc

 

and unload it after using with:
public function boolean of_removefont (readonly string as_fontfile):
boolean    lb_rc

lb_rc = RemoveFontResourceExW( as_FontFile, 16 /* FR_PRIVATE 0x10 */ + 32 /* FR_NOT_ENUM 0x20 */, 0 )

return lb_rc

 

...of_AddFont( "c:\Temp\MyFont.ttf" )
// Use font
... of_RemoveFont( "c:\Temp\MyFont.ttf" )

 

I called "of_AddFont()" on application start and "of_RemoveFont()" on application close.

Hope this helps,
Regards
Bernhard

Hi All,

 

If you enable the packaging custom fonts in the generated PDF files for NativePDF, then you can't use AddFontResourceExW function to mark a font as not enumerable.

We suggest that you use AddFontResourceExW and RemoveFontResourceExW functions and do not specify the FR_NOT_ENUM parameter any longer.

The reference code is as follows:

 

AddFontResourceExW( ls_DynLoadedFontFile, 16 /* FR_PRIVATE 0x10 */, 0)

RemoveFontResourceExW( ls_DynLoadedFontFile, 16 /* FR_PRIVATE 0x10 */, 0)

 

Regards,

FYI- appeon's native PDF will NOT work with this.

use @mark's suggestion to make it private only (16): AddFontResourceExW( ls_DynLoadedFontFile, 16 , 0) and it will work with native pdf!
