Package graphicscommand represents a low layer for graphics using OpenGL.
command.go doc.go image.go shader.go thread.go
FlushCommands flushes the command queue.
MaxImageSize returns the maximum size of an image.
ResetGraphicsDriverState resets or initializes the current graphics driver state.
type Image struct {
// contains filtered or unexported fields

Image represents an image that is implemented with OpenGL.
NewImage returns a new image.
Note that the image is not initialized yet.
func (i *Image) DrawTriangles(srcs [graphics.ShaderImageNum]*Image, offsets [graphics.ShaderImageNum - 1][2]float32, vertices []float32, indices []uint16, clr *affine.ColorM, mode driver.CompositeMode, filter driver.Filter, address driver.Address, dstRegion, srcRegion driver.Region, shader *Shader, uniforms []interface{})
DrawTriangles draws triangles with the given image.
The vertex floats are:
0: Destination X in pixels 1: Destination Y in pixels 2: Source X in pixels (not texels!) 3: Source Y in pixels 4: Color R [0.0-1.0] 5: Color G 6: Color B 7: Color Y
src and shader are exclusive and only either is non-nil.
The elements that index is in between 2 and 7 are used for the source images. The source image is 1) src argument if non-nil, or 2) an image value in the uniform variables if it exists. If there are multiple images in the uniform variables, the smallest ID's value is adopted.
If the source image is not specified, i.e., src is nil and there is no image in the uniform variables, the elements for the source image are not used.
Dump dumps the image to the specified path. In the path, '*' is replaced with the image's ID.
If blackbg is true, any alpha values in the dumped image will be 255.
This is for testing usage.
Pixels returns the image's pixels. Pixels might return nil when OpenGL error happens.
Sync syncs the texture data in CPU and GPU so that Pixels can return the texture data immediately. In most cases, Sync doesn't have to be called explicitly. Even without Sync, Pixels should does Sync automatically, but this might take long.
Sync returns a channel that is closed when syncing finishes.
