TTF_OpenFontDPI

Create a font from a file, using target resolutions (in DPI).

Syntax

TTF_Font * TTF_OpenFontDPI(const char *file, int ptsize, unsigned int hdpi, unsigned int vdpi);

Function Parameters

file

path to font file.

ptsize

point size to use for the newly-opened font.

hdpi

the target horizontal DPI.

vdpi

the target vertical DPI.

Return Value

Returns a valid TTF_Font, or NULL on error.

Remarks

DPI scaling only applies to scalable fonts (e.g. TrueType).

Some .fon fonts will have several sizes embedded in the file, so the point size becomes the index of choosing which size. If the value is too high, the last indexed size will be the default.

When done with the returned TTF_Font, use TTF_CloseFont() to dispose of it.

Version

This function is available since SDL_ttf 2.0.18.
