How to add Custom Fonts to EFI Applicaiton

[kowalski100]

My EFI application has a simple UI which displays some info using simple fonts in edk2 (built-in). I am unable to increase the size of fonts, make it bold, italic etc. Is it possible? I have no luck with it if not how i can add custom fonts and sizes etc. any useful guide?

My logic:

        // Draw the character
        Status = mGraphicsOutputProtocol->Blt(
            mGraphicsOutputProtocol,
            CharBuffer,
            EfiBltBufferToVideo,
            0, 0,                          // Source X, Y
            StartX + (Index * EFI_GLYPH_WIDTH),  // Destination X
            StartY,                         // Destination Y
            EFI_GLYPH_WIDTH,
            EFI_GLYPH_HEIGHT,
            0
        );

To my knowledge, this isn't possible without HII (via EFI_HII_FONT_PROTOCOL.StringToImage().

You may also find the EFI_HII_FONT_STYLE bitfield and EFI_FONT_DISPLAY_INFO useful for accomplishing your goal

Edit: There is also a PoC for using Freetype with EDK-II showing that it's possible to accomplish this without HII
