Contents
Data Fields
const char* |
name |

Uint32 |
num_texture_formats |
the number of available texture formats |
Uint32[16] |
texture_formats |
the available texture formats; see Remarks for details |
int |
max_texture_width |
the maximum texture width |

Remarks
flags may be 0 or a mask of any of the following SDL_RendererFlags values OR'd together:
SDL_RENDERER_SOFTWARE |
the renderer is a software fallback |
SDL_RENDERER_ACCELERATED |
the renderer uses hardware acceleration |
SDL_RENDERER_PRESENTVSYNC |
present is synchronized with the refresh rate |
SDL_RENDERER_TARGETTEXTURE |
the renderer supports rendering to texture |
Note that providing no flags gives priority to available SDL_RENDERER_ACCELERATED renderers.
texture_formats is an array of SDL_PixelFormatEnum values representing the available texture formats for the renderer
Pixel Format Macros
SDL_PIXELTYPE(format) |
the type of the pixel format; see Remarks for details |
SDL_PIXELORDER(format) |
the ordering of channels or bits in the pixel format; see Remarks for details |
SDL_PIXELLAYOUT(format) |
the channel bit pattern of the pixel format; see Remarks for details |
SDL_BITSPERPIXEL(format) |
the number of bits of color information in the pixel format |
SDL_BYTESPERPIXEL(format) |
the number of bytes used to represent a pixel |
SDL_ISPIXELFORMAT_INDEXED(format) |
true for pixel formats that have a palette |
SDL_ISPIXELFORMAT_ALPHA(format) |
true for pixel formats that have an alpha channel |
SDL_ISPIXELFORMAT_FOURCC(format) |
true for pixel formats representing unique formats, for example YUV formats |
