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).

#define B_COEF   107
 Blue component sensivity.
#define G_COEF   242
 Green component sensivity.
#define R_COEF   173
 Red component sensivity.

Eye sensivity to different color components, squared

#define B_COEF_SQ   114
 Blue component sensivity, squared.
#define G_COEF_SQ   587
 Green component sensivity, squared.
#define R_COEF_SQ   299
 Red component sensivity, squared.

Functions

csPtr< iImagecsCreateXORPatternImage (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.
static csRef< iImagecsBakeKeyColor::Image (iImage *source, const csRGBpixel &transpColor)
 Set alpha of all pixels to 0 that match transpColor.

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.
