ttfOpenFontDpirw function

Pointer<TtfFont> ttfOpenFontDpirw(
  1. Pointer<SdlRWops> src,
  2. int freesrc,
  3. int ptsize,
  4. int hdpi,
  5. int vdpi,
)

Opens a font from an SDL_RWops with target resolutions (in DPI).

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.

If freesrc is non-zero, the RWops will be automatically closed once the font is closed. Otherwise you should close the RWops yourself after closing the font.

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

\param src an SDL_RWops to provide a font file's data. \param freesrc non-zero to close the RWops when the font is closed, zero to leave it open. \param ptsize point size to use for the newly-opened font. \param hdpi the target horizontal DPI. \param vdpi the target vertical DPI. \returns a valid TTF_Font, or NULL on error.

\since This function is available since SDL_ttf 2.0.18.
