This example demonstrates wooden, rocky and marble texture effects by using pattern colors to load image patterns.
In ChartDirector, metallic and pattern colors are just like normal ARGB colors, and are represented as a 32-bit integer. They can be applied to anything that can be colored. In this example, metallic colors are applied to the background, while pattern colors are applied to the donut slices to create texture effects.
- BaseChart.patternColor2 is used to load the texture images. It returns an array of integers representing the pattern colors created from the images.
- The pattern colors are then set into the DataColor positions of the default palette using BaseChart.setColor. These colors will be used for the sectors.
