Member Function Documentation

◆ getOriginalRegionImage()

DImg Digikam::ImageRegionWidget::getOriginalRegionImage ( bool  useDownscaledImage = false) const

Should be use to increase preview speed for the effects whose behaviour is a function of each pixel.

◆ mouseMoveEvent()

void Digikam::ImageRegionWidget::mouseMoveEvent ( QMouseEvent *  e)
overrideprotectedvirtual

Reimplemented from Digikam::GraphicsDImgView.

◆ mousePressEvent()

void Digikam::ImageRegionWidget::mousePressEvent ( QMouseEvent *  e)
overrideprotectedvirtual

Reimplemented from Digikam::GraphicsDImgView.

◆ mouseReleaseEvent()

void Digikam::ImageRegionWidget::mouseReleaseEvent ( QMouseEvent *  e)
overrideprotectedvirtual

Reimplemented from Digikam::GraphicsDImgView.

◆ setBusy()

void Digikam::ImageRegionWidget::setBusy ( bool  b)

The canvas update can be processed only when the filter complete the job. Typical case of dysfunction: zoom out the canvas with a preview redending an half of the image. Due to a race condition, an older area is flush on the part of the image to render and still present while the filter is done.
