We want the users to enter the CMYK values for the @fill parameter of tag. When we run imageinfo on a psd file created with CMYK we see the following as an example:
fill = 'CMYK(6417bb00)'

These values don't correspond to the percentage values that we expect to see for CMYK as in Photoshop/Illustrator applications.

Any help to figure out how to get these values from a desired color will be greatly appreciated.

Thanks,
Bipin Raj

Search on "fill" in the Developers Guide and XML Reference.

There are a number of examples. They use the hex format where violet= "#FF00FF"

For CMYK, the color is usually expressed in percentage. If the CMYK values are (10%, 15%, 20%, 25%) how is this expressed in the hex format for CMYK? The hex values that I found in the Developers guide and XML Reference are for expressing RGB colors, which is why there are 6 digits and not 8 digits.

Thanks,

The syntax is slightly different for CMYK vs RGB in the set command
- for RGB value="#CCC0D4"
- for CMYK value="cmyk(1a26121a)"

Your code will have to convert the percentage values to hex
As a % 10% C, 15% M, 7% Y, 10% K
As hex: 1a26121a

Is there a way to get named colors to work with SVG ( such as Pantone ) ? I would like to use SVG templates for printing purposes. I heard of SVGP but I can't find any new about this...

Thanks

Recognize that SVG was created as a Web format and is RGB only. (I've heard talk of adding CMYK support to the SVG specification but I dont' know how far along that is.)

In any case, AGS only supports RGB SVGs.
