unsigned char * | d_pixels |
Pixel data. |
|
Construct. |
|
Construct. Note that the pixels read from lower left to upper right, which is a reflection around the y-axis from the "normal" convention. Note also that width and height are specified in pixels, and a pixel may be more than one byte wide. For example, an image with a width and height of 16, and nc==3, would have a pixel array w*h*nc = 16*16*3 = 768 bytes long. See the class intro above for the interpretation of different pixel depths.
