###### (This function is part of SDL_ttf, a separate library from SDL.) # TTF_OpenFontDPI Create a font from a file, using target resolutions (in DPI). ## Syntax ```c 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](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](TTF_Font), use [TTF_CloseFont](TTF_CloseFont)() to dispose of it. ## Version This function is available since SDL_ttf 2.0.18. ## Related Functions * [TTF_CloseFont](TTF_CloseFont) ---- [CategoryAPI](CategoryAPI)
