Image Manipulation

[Baker]

To do list:

HARD

* Rotate by angle (Hard?)
* color quantization with X colors (i.e. reduce color depth to X and select X colors to represent entire image)

EASY

* Resample
* Crop
* "Enlarge Canvas"
* Gamma Adjust
* Contrast Adjust
* Count colors used
* cut
* paste at x,y
* generic color swap without tolerance
* create thumbnail (basically same as resample)

MEDIUM

* fill at x,y with color
* generic color swap with some sort of tolerance
* HSL stuff (hue saturation luminance) hue = atan2(2 * r - g - b, cube root of 3 * (g - b))
* Draw fixed width font at x, y; draw fixed width font at r, c

[Other thoughts: how to define a complicated selection. Thoughts on drawing a line, circle, freehand with a brush]

would it not be better to calculate the pixels in the dest, rather than projecting the source? then you won't have issues with gaps when eg rotating/scaling up.

I'm kind of trying to see inside of what is really happening in both software rendering and hardware rendering, I've been working out maths most of the day. I'm understanding the software renderer and hardware renderer, seeing what the matrixes are doing with the calculations, etc. So I'm kinda of going for the "unshielded" approach and instead of avoiding the hard things, I'm specifically engaging them.

Yeah this slows me down for the moment, but if I'd rather be in a position where I can, say, look at some clipping or collision or rotation or transformation code and see what is going on directly.
