| |
|
pure virtual |
Invalidates a specified rectangle area on the given set of layers. The rectangle area is specified in pixel coordinates.
- Parameters
-
| renderer | the renderer to which this render target has been bound. |
| x | the x position of the rectangle area (view coordinates in pixel). |
| y | the y position of the rectangle area (view coordinates in pixel). |
| width | the width of the rectangle area (view coordinates in pixel). |
| height | the height of the rectangle area (view coordinates in pixel). |
| layers | the set of layers to invalidate. |
◆ supportsOffscreenRendering()
| virtual bool myscript::iink::IRenderTarget::supportsOffscreenRendering |
( |
| ) |
|
|
inlinevirtual |
Indicates whether this render target supports offscreen rendering.
- Returns
true if offscreen rendering is supported, otherwise false.
- Since
- 2.0
◆ getPixelDensity()
| virtual float myscript::iink::IRenderTarget::getPixelDensity |
( |
| ) |
|
|
inlinevirtual |
Returns the render target pixel density
- Note
- also known as DIP, density-independent pixels on Android, or dppx.
- Since
- 2.0

( |
int |
width, |

bool |
alphaMask |
|
) |
| |
|
inlinevirtual |
Requests the creation of an offscreen render surface (e.g. a bitmap), and returns a unique identifier for that surface.
- Note
- createOffscreenRenderCanvas() will be called with this identifier, to request drawing of the associated surface.
- Parameters
-
| width | the width of the surface to create (view coordinates in pixel). |
| height | the height of the surface to create (view coordinates in pixel). |
| alphaMask | request creation of an alpha mask. Only the alpha channel is relevant. The actual red, green and blue channel values are given by the blend color. |
- Returns
- the identifier of the created surface.
- Since
- 2.0
◆ releaseOffscreenRenderSurface()
| virtual void myscript::iink::IRenderTarget::releaseOffscreenRenderSurface |
( |
uint32_t |
surfaceId | ) |
|
|
inlinevirtual |
Requests the release of the offscreen render surface associated with a given identifier.
- Parameters
-
| surfaceId | the identifier of the surface to release. |
- Since
- 2.0
◆ createOffscreenRenderCanvas()
| virtual std::shared_ptr< graphics::ICanvas > myscript::iink::IRenderTarget::createOffscreenRenderCanvas |
( |
uint32_t |
surfaceId | ) |
|
|
inlinevirtual |
Creates a Canvas that draws onto the offscreen render surface associated with a given identifier.
- Parameters
-
| surfaceId | the identifier of the surface to be drawn. |
- Returns
- a Canvas to draw on the requested surface.
- Since
- 2.0
◆ releaseOffscreenRenderCanvas()
| virtual void myscript::iink::IRenderTarget::releaseOffscreenRenderCanvas |
( |
graphics::ICanvas * |
canvas | ) |
|
|
inlinevirtual |
Requests the release of an offscreen render canvas.
- Parameters
-
| canvas | the canvas to release. |
- Since
