## Eye sensivity to different color components
Eye sensivity to different color components, from NTSC grayscale equation. The coefficients are multiplied by 100 and rounded towards nearest integer, to facilitate integer math. The squared coefficients are also multiplied by 100 and rounded to nearest integer (thus 173 == 1.73, 242 == 2.42 etc).

## Function Documentation

csPtr<iImage> csCreateXORPatternImage | ( | int | width,
|  | int | height,
|  | int | recdepth,
|  | float | red = `1.0f`,
|  | float | green = `1.0f`,
|  | float | blue = `1.0f` |
| ) |  |  |

Create an iImage with a nice XOR pattern with 2^`recdepth` shades of from white to black.

Parameters:

  | width | Width of the image to create
  | height | Height of the image to create
  | recdepth | "recursion depth", clamped to range 1-8.
  | red | Maximum value of red component
  | green | Maximum value of green component
  | blue | Maximum value of blue component

static csRef<iImage> csBakeKeyColor::Image | ( | iImage * | source,
|  | const csRGBpixel & | transpColor |
| ) |  |  | `[static, inherited]`

Set alpha of all pixels to 0 that match transpColor.

The color of pixels made transparent is changed such that it has the average color of some near non-transparent pixels to prevent halos.

Remarks:
  Intermediately uses a truecolor images, i.e. paletted images are not handled with maximum efficiency.
