Function documentation

std::shared_ptr<ImageRenderer> fast::ImageRenderer::create(float level, float window, float opacity, bool applyTransformationsIn2D) override

Create instance.

Parameters
level
window
opacity Draw image with an opacity. Useful if you want to draw an image on top of another
applyTransformationsIn2D In 2D transformations (rotation/translation) are typically not applied. by setting this to true they will be applied.
Returns instance
