/**
* @brief Given a transform string, returns a colortransform struct
*
* @param Trans a colortransform pointer to hold the transform
* @param TransformString string specifying the transformations
* @return 1 on success, 0 on failure
*
* This function provides a convenient interface to the collection of transform
* functions in this file. TransformString specifies the source and
* destination color spaces,
* TransformString = "dest<-src"
* or alternatively,
* TransformString = "src->dest".
*
* Supported color spaces are
* "RGB" sRGB Red Green Blue (ITU-R BT.709 gamma-corrected),
* "YPbPr" Luma (ITU-R BT.601) + Chroma,
* "YCbCr" Luma + Chroma ("digitized" version of Y'PbPr),
* "JPEG-YCbCr" Luma + Chroma space used in JFIF JPEG,
* "YUV" NTSC PAL Y'UV Luma + Chroma,
* "YIQ" NTSC Y'IQ Luma + Chroma,
* "YDbDr" SECAM Y'DbDr Luma + Chroma,
* "HSV" or "HSB" Hue Saturation Value/Brightness,
* "HSL" or "HLS" Hue Saturation Luminance,
* "HSI" Hue Saturation Intensity,
* "XYZ" CIE XYZ,
* "Lab" CIE L*a*b* (CIELAB),
* "Luv" CIE L*u*v* (CIELUV),
* "LCH" CIE L*C*H* (CIELCH),
* "CAT02 LMS" CIE CAT02 LMS.
* Color space names are case-insensitive and spaces are ignored. When sRGB
* is the source or destination, it can be omitted. For example "yuv<-" is
* short for "yuv<-rgb".
*
* The routine returns a colortransform structure representing the transform.
* The transform is performed by calling GetColorTransform. For example,
@code
num S[3] = {173, 0.8, 0.5};
num D[3];
colortransform Trans;
if(!(GetColorTransform(&Trans, "HSI -> Lab")))
{
printf("Invalid syntax or unknown color space\n");
return;
