[texhax] [NTG-pdftex] \pdfximage : is there a transparency attribute or method ?

[Philip TAYLOR (Webmaster, Ret'd)]

A supplementary question, if I may ?  The PdfTeX
reference manual as found at Tug.Org has Chapter
Eight entitled "Graphics and color", yet the
chapter seems not to mention colour at all and
focuses solely on graphics.  Section 7.12 says
"\pdfliteral [ <pdfliteral spec> ] <general text>
Like \special in normal TEX, this command inserts
raw pdf code into the output. This allows support
of color and text transformation." but as far as
I can tell, there are no examples of suitable
parameters for affecting the colour of (e.g.)
rendered text.  May I ask if there is a supplementary
manual that defines how colour is to be programmed
through PdfTeX ?
