Package: cairo
Function cairo:pattern-add-color-stop-rgb
Lambda Listcairo:pattern-add-color-stop-rgb (pattern offset red green blue) ArgumentsDetails
Adds an opaque color stop to a gradient pattern.
The offset specifies the location along the gradient's control vector. For example, a linear control vector of the pattern is from (x0,y0) to (x1,y1) while a radial control vector of the pattern is from any point
on the start circle to the corresponding point on the end circle. The color is specified in the same way as in the cairo:set-source-rgb function. If two (or more) stops are specified with identical offset values, they will be sorted according to the order in which the stops are added, stops added earlier will compare less than stops added later. This can be useful for reliably making sharp color transitions instead of the typical blend. NotesLisp implementation | See also |
