| virtual void uicore::Canvas::begin |
( |
| ) |
|
|
pure virtual |
Marks the start of a canvas rendering pass.
Prepares the graphic context for rendering by binding the appropriate state.
Clears the whole context using the specified color.
| virtual Rectf uicore::Canvas::clip |
( |
| ) |
const |
|
pure virtual |
Returns the current clipping rectangle.
| virtual void uicore::Canvas::end |
( |
| ) |
|
|
pure virtual |
Marks the end of a canvas rendering pass.
All batched rendering requests are flushed and the graphic context state is reset to its defaults.
Returns the graphic context associated with this canvas.

( |
const Pointf & |
pos | ) |
|
|
pure virtual |
Snaps the point to the nearest pixel corner.
| virtual float uicore::Canvas::height |
( |
| ) |
const |
|
pure virtual |
Returns the current height of the context.
| virtual const Mat4f& uicore::Canvas::inverse_transform |
( |
| ) |
const |
|
pure virtual |
Returns the inverse of the transform matrix.

| virtual void uicore::Canvas::pop_clip |
( |
| ) |
|
|
pure virtual |
Pop current clipping rectangle from the stack.
| virtual const Mat4f& uicore::Canvas::projection |
( |
| ) |
const |
|
pure virtual |
Returns the current effective projection matrix.
| virtual void uicore::Canvas::push_clip |
( |
const Rectf & |
rect | ) |
|
|
pure virtual |
Push current clipping rectangle to stack.
If a rectangle is passed, it afterwards sets clipping rectangle to the union of the current rectangle and the passed rectangle.
