I have some questions about the handling of colour which I will ask of the list generally, although I noticed Tore's recent colour related contributions, so he may be the one to enlighten me.
Color (to use the official spelling) is one of those areas of the spec whose precise description is deferred to other documents, so I am hoping someone on the list has done all of the hard work. In .../datatypes/ColorType.java the ColorType is defined as a set of floating point numbers: red, green, blue and alpha. From the code, it is apparent that the RGB components are in the range 0 to 1.0. Is this also true of alpha? Why this particular representation? Is it mandated in the sRGB document, or is it the representation used by PDF? What is a color profile? In the recently updated (by Tore) ColorSpace.java, it is represented as a byte array. What is the function of this byte array? What is the relationship between the the linear RGB space and sRGB, which, from my glance at the document, seems to involve a color profile, and between the sRGB and the ICC color profiles? All information will be gratefully received. Peter -- Peter B.
