Synopsis

bool pdf_setcolor(pdf, mode, colorspace, c1[, c2][, c3][, c4]); resource pdf: PDF object identifier string mode: Color mode string colorspace: Color space type double c1: Color one double c2 (optional): Color two double c3 (optional): Color three double c4 (optional): Color four

Returns

Always TRUE

Description

A relatively complex function but once the principles have been grasped, it's useful to know. pdf_setcolor() controls the behaviour and type of nearly any aspect of the document involving color. Depending on what the value of colorspace is set to, other parameters may or may not be required.

type should be stroke, fill or both and controls which which parts of an object is colored when using pdf_stroke() , pdf_fill() , or pdf_fill_stroke() .

colorspace can be gray, rgb, cmyk, spot or pattern. If colorspace is gray then c1 specifies a gray value. If colorspace is rgb then c1 , c2 and c3 specify red,green,and blue values. If colorspace is cmyk then c1 , c2 , c3 and c4 specify cyan,magenta,yellow,and black values. If colorspace is spot then c1 specifies a spot color handle returned by pdf_makespotcolor() and c2 specifies a tint value between 0 and 1. If colorspace is pattern then c1 specifies a pattern handle returned by pdf_begin_pattern() .

Version

Since version 4.0.5
