Types ¶
type Image ¶
type Image struct {
// contains filtered or unexported fields
}
func (*Image) DrawTriangles ¶
func (i *Image) DrawTriangles(srcs [graphics.ShaderImageCount]*Image, vertices []float32, indices []uint16, colorm affine.ColorM, mode graphicsdriver.CompositeMode, filter graphicsdriver.Filter, address graphicsdriver.Address, dstRegion, srcRegion graphicsdriver.Region, subimageOffsets [graphics.ShaderImageCount - 1][2]float32, shader *Shader, uniforms [][]float32, evenOdd bool)
DrawTriangles draws the src image with the given vertices.
Copying vertices and indices is the caller's responsibility.
func (*Image) DumpScreenshot ¶
func (*Image) MarkDisposed ¶
func (i *Image) MarkDisposed()
func (*Image) ReplacePixels ¶
ReplacePixels replaces the pixels at the specified region.
