SOD C/C++ API Reference - Image Processing


void sod_scale_image_channel(sod_img input, int c, float v);


Perform constant value multiplication on each pixel of a selected color channel unlike sod_scale_image() which process the entire image (i.e. all channels).


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().

int    c

The target color channel starting from 0 for Red, 1 for Green and 2 for Blue in a typical RGB colorspace. Note that in a grayscale image, this value must be set to 0.

float    s

Constant value to multiply with each single pixel of the target color channel. This value must be set between 0..1 such as 0.7.

Return Value
