TTF_GetGPUTextDrawData3
Get the geometry data needed for drawing the text.
Usage
#include "SDL3_ttf/SDL_ttf.h"
TTF_GPUAtlasDrawSequence * TTF_GetGPUTextDrawData(TTF_Text *text);
Header file
Defined in SDL3_ttf/SDL_ttf.h
Overview
text must have been created using a TTF_TextEngine
from
TTF_CreateGPUTextEngine ().
The positive X-axis is taken towards the right and the positive Y-axis is taken upwards for both the vertex and the texture coordinates, i.e, it follows the same convention used by the SDL_GPU API. If you want to use a different coordinate system you will need to transform the vertices yourself.
If the text looks blocky use linear filtering.
Function parameters
- text
-
the text to draw.
Return value
( TTF_GPUAtlasDrawSequence
*) Returns a NULL terminated linked list of
TTF_GPUAtlasDrawSequence
objects or NULL if the passed text is empty or in case of failure; call SDL_GetError() for more information.
Thread safety
This function should be called on the thread that created the text.
