8.1
The vizfx.postprocess.transform library is a collection of effects that perform various transformations on the rendered image.
Flips the image horizontally and/or vertically.
|
Constructor |
Description |
|
FlipEffect( horizontal = False, vertical = False ) |
Create the flip effect with the initial horizontal and vertical flip flags. |
Method | Description |
<effect>.setFlipHorizontal(flip) | Set whether to flip image horizontally. |
<effect>.getFlipHorizontal() | Get if image is flipped horizontally. |
<effect>.setFlipVertical(flip) | Set whether to flip image vertically. |
<effect>.getFlipVertical() | Get if image is flipped vertically. |
This effect can be registered with vizconfig.
Translate the image.
Constructor | Description |
TranslateEffect( translate = (0.0,0.0), repeat = False } | Create the translate effect with the initial translate offset and repeat flag. |
Method | Description |
<effect>.setTranslate(value) | Set the [x,y] translation in normalized (0-1) units. |
<effect>.getTranslate() | Get the [x,y] translation in normalized (0-1) units. |
<effect>.setRepeat(value) | Set whether to repeat the image when UV coordinates are outside (0-1) range. |
<effect>.getRepeat() | Get whether to repeat the image when UV coordinates are outside (0-1) range. |
This effect can be registered with vizconfig.
Rotate the image about a specified center.
Constructor | Description |
RotateEffect( angle = 0.0, center = (0.5,0.5), repeat = False ) | Create the rotate effect with the initial rotation angle, center, and repeat flag. |
Method | Description |
<effect>.setAngle(value) | Set the rotation angle, in degrees. Positive angles rotate clockwise. |
<effect>.getAngle() | Get the rotation angle, in degrees. |
<effect>.setCenter(value) | Set the [x,y] center to rotate about, in normalized (0-1) units. |
<effect>.getCenter() | Get the [x,y] center to rotate about, in normalized (0-1) units. |
<effect>.setRepeat(value) | Set whether to repeat the image when UV coordinates are outside (0-1) range. |
<effect>.getRepeat() | Get whether to repeat the image when UV coordinates are outside (0-1) range. |
This effect can be registered with vizconfig.
Scale the image about a specified center.
Constructor | Description |
ScaleEffect( scale = (1.0,1.0), center = (0.5,0.5), repeat = False ) | Create the scale effect with the initial scale factor, center, and repeat flag. |
Method | Description |
<effect>.setScale(value) | Set the [x,y] scale factor. |
<effect>.getScale() | Get the [x,y] scale factor. |
<effect>.setCenter(value) | Set the [x,y] center to scale about, in normalized (0-1) units. |
<effect>.getCenter() | Get the [x,y] center to scale about, in normalized (0-1) units. |
<effect>.setRepeat(value) | Set whether to repeat the image when UV coordinates are outside (0-1) range. |
<effect>.getRepeat() | Get whether to repeat the image when UV coordinates are outside (0-1) range. |
This effect can be registered with vizconfig.
