void | av_image_fill_max_pixsteps (int max_pixsteps[4], int max_pixstep_comps[4], const AVPixFmtDescriptor *pixdesc) |
Compute the max pixel step for each plane of an image with a format described by pixdesc. | |
int | av_image_get_linesize (enum PixelFormat pix_fmt, int width, int plane) |
Compute the size of an image line with format pix_fmt and width width for the plane plane. | |
int | av_image_fill_linesizes (int linesizes[4], enum PixelFormat pix_fmt, int width) |
Fill plane linesizes for an image with pixel format pix_fmt and width width. | |
int | av_image_fill_pointers (uint8_t *data[4], enum PixelFormat pix_fmt, int height, uint8_t *ptr, const int linesizes[4]) |
Fill plane data pointers for an image with pixel format pix_fmt and height height. | |
int | av_image_alloc (uint8_t *pointers[4], int linesizes[4], int w, int h, enum PixelFormat pix_fmt, int align) |
Allocate an image with size w and h and pixel format pix_fmt, and fill pointers and linesizes accordingly. | |
void | av_image_copy_plane (uint8_t *dst, int dst_linesize, const uint8_t *src, int src_linesize, int bytewidth, int height) |
Copy image plane from src to dst. | |
void | av_image_copy (uint8_t *dst_data[4], int dst_linesizes[4], const uint8_t *src_data[4], const int src_linesizes[4], enum PixelFormat pix_fmt, int width, int height) |
Copy image in src_data to dst_data. | |
int | av_image_check_size (unsigned int w, unsigned int h, int log_offset, void *log_ctx) |
Check if the given dimension of an image is valid, meaning that all bytes of the image can be addressed with a signed int. | |
int | ff_set_systematic_pal2 (uint32_t pal[256], enum PixelFormat pix_fmt) |
