func Error ¶ Uses

Error returns an OpenGL error for the last command.

func FlushCommands ¶ Uses

FlushCommands flushes the command queue.

func NeedsRestoring ¶ Uses

func ResetGraphicsDriverState ¶ Uses

ResetGraphicsDriverState resets or initializes the current graphics driver state.

func SetGraphicsDriver ¶ Uses

type Image ¶ Uses

Image represents an image that is implemented with OpenGL.

func NewImage ¶ Uses

NewImage returns a new image.

Note that the image is not initialized yet.

func NewScreenFramebufferImage ¶ Uses

func (*Image) Dispose ¶ Uses

func (*Image) DrawTriangles ¶ Uses

func (*Image) Dump ¶ Uses

Dump dumps the image to the specified path. In the path, '*' is replaced with the image's ID.

This is for testing usage.

func (*Image) InternalSize ¶ Uses

func (*Image) IsInvalidated ¶ Uses

func (*Image) Pixels ¶ Uses

Pixels returns the image's pixels. Pixels might return nil when OpenGL error happens.

func (*Image) ReplacePixels ¶ Uses
