Is it possible to use PCL XL to print CMYK composite halftone (1-bit) data? Or do I have to somehow convert it to 8bit RGB data?

Does anyone know how to create a texture with a YUV colorspace so that we can get hardware based YUV to RGB colorspace conversion without having to use a fragment shader? I'm using an NVidia 9400 and I don't see an obvious GL extension that seems to do the trick. I've found examples how to use a…

I understand RGB --- value (0-255)Red,(0-255)Green,(0-255)Blue to form a color.
What is exactly BGR color space ?
How is it different from RGB color space ?

These smaller photos are for display in an online gallery. Many of the photographers are submitting JPEG images using Adobe RGB.
I would like to use sRGB for all thumbnails and medium size images
I am using dotnet (asp.net)…

Is there a canonical colorspace conversion library? I can't find any pre-existing solutions. Is CIELab conversion is too obscure?
Thanks

I plan to write a painting program based on linear combinations of xy plane points (0,1), (1,0 ) and (0,0). Such system works identically to RGB, except that the primaries are not within the gamut but at the corners of a triangle that encloses the entire gamut, therefore allowing for all colors to…

Suppose there are two colors defined in CMYK:
color1 = 30, 40, 50, 60
color2 = 50, 60, 70, 80
If they were to be printed what values would the resulting color have?
color_new = min(cyan1 + cyan2, 100), min(magenta1 + magenta2, 100), min(yellow1 + yellow2, 100), min(black1 + black2, 100)?
Suppose…

I have a problem with converting a CMYK Color to RGB.
In the internet there is many formulas to convert it but for example when I convert CMYK (0,100,100,0) to RGB, it get value (255 0 0) but in Adobe Photoshop RGB value is (237,28,36) and I want this one. Is anybody know how to convert it with java…

Hi,
I have a CMYK colorspace in indesign, i want to convert that as RGB color space, I got some codes, but I am getting incorrect data.
Some of the codes which I tried are given below
double cyan = 35.0;
double magenta = 29.0;
double yellow = 0.0;
double black = 16.0;
