RGtk2 (version 2.20.30)

cairoPatternCreateLinear: cairoPatternCreateLinear

Description

Create a new linear gradient CairoPattern along the line defined by (x0, y0) and (x1, y1). Before using the gradient pattern, a number of color stops should be defined using cairoPatternAddColorStopRgb or cairoPatternAddColorStopRgba.

Usage

cairoPatternCreateLinear(x0, y0, x1, y1)

Value

[CairoPattern] the newly created CairoPattern if successful, or an error pattern in case of no memory. This function will always return a valid pointer, but if an error occurred the pattern status will be set to an error. To inspect the status of a pattern use cairoPatternStatus.

Details

Note: The coordinates here are in pattern space. For a new pattern, pattern space is identical to user space, but the relationship between the spaces can be changed with cairoPatternSetMatrix.
