Parameters
| Parameter | Type | Default value | Description |
|---|---|---|---|
angle | number | undefined | The rotation angle, in radians. |
order | "after" | "before" | 'after' | The order in which to add the translation (defaults to 'after'): * 'before' - Applies the rotation before this stream's current transformation. * 'after' - Applies the rotation after this stream's current transformation. |
Returns
this
This stream, after its transformation has been changed.
addScale()
addScale(
factor,order):this
Defined in: src/sdk/graphics/path/AffineTransformPathStream.ts:56
Adds a uniform scaling to this stream's transformation.
Parameters
| Parameter | Type | Default value | Description |
|---|---|---|---|
factor | number | undefined | The scaling factor. |
order | "after" | "before" | 'after' | The order in which to add the translation (defaults to 'after'): * 'before' - Applies the scaling before this stream's current transformation. * 'after' - Applies the scaling after this stream's current transformation. |
Returns
this
This stream, after its transformation has been changed.
addTranslation()
addTranslation(
x,y,order):this
Defined in: src/sdk/graphics/path/AffineTransformPathStream.ts:32
Adds a translation to this stream's transformation.
Parameters
| Parameter | Type | Default value | Description |
|---|---|---|---|
x | number | undefined | The x translation. |
y | number | undefined | The y translation. |
order | "after" | "before" | 'after' | The order in which to add the translation (defaults to 'after'): * 'before' - Applies the translation before this stream's current transformation. * 'after' - Applies the translation after this stream's current transformation. |
Returns
this
This stream, after its transformation has been changed.
