Syntax
sod_img sod_rotate_crop_image(sod_img input, float rad, float s, int w, int h, float dx, float dy, float aspect);Description
Rotates & Crop an image to the specified number of degrees and dimension. For standard image rotation & cropping, you should rely respectively on sod_rotate_image() and sod_crop_image().
Parameters
sod_img input
The input image to be processed. The image can be loaded from disk using sod_img_load_from_file(), from memory (i.e. network socket) via sod_img_load_from_mem() or dynamically created via sod_make_image().
float rad
The rotation angle, in degrees. The rotation angle is interpreted as the number of degrees to rotate the image clockwise.
float s
Scale factor of the crop.
int w
The width of the crop.
int h
The height of the crop.
int dx
The x-coordinate, in logical units of the crop offset.
int dy
The y-coordinate, in logical units of the crop offset.
float aspect
Aspect ratio of the crop.
Return Value
Processed image is returned in an instance of the sod_img object. if something goes wrong during processing, then an empty image is returned via sod_make_empty_image(). Once done, you must release the memory allocated to this object via sod_free_image() to avoid memory leaks.
