Member Function Documentation

◆ redo()

void KisLayerUtils::SplitAlphaCommand::redo ( )

inlineoverridevirtual

Applies a change to the document. This function must be implemented in the derived class. Calling KUndo2QStack::push(), KUndo2QStack::undo() or KUndo2QStack::redo() from this function leads to undefined behavior.

The default implementation calls redo() on all child commands.

See also: undo()

Reimplemented from KUndo2Command.

Definition at line 802 of file kis_layer_utils.cpp.

                             {
            KisPaintDeviceSP srcDevice = m_info->node->paintDevice();
            const KoColorSpace *srcCS = srcDevice->colorSpace();
            const QRect processRect =
                    srcDevice->exactBounds() |
                    srcDevice->defaultBounds()->bounds();
 
            KisSequentialIterator srcIt(srcDevice, processRect);
            KisSequentialIterator dstIt(m_info->getMaskDevice(), processRect);
 
            while (srcIt.nextPixel() && dstIt.nextPixel()) {
                quint8 *srcPtr = srcIt.rawData();
                quint8 *alpha8Ptr = dstIt.rawData();
 
                *alpha8Ptr = srcCS->opacityU8(srcPtr);
                srcCS->setOpacity(srcPtr, OPACITY_OPAQUE_U8, 1);
            }
        }

◆ undo()

void KisLayerUtils::SplitAlphaCommand::undo ( )

inlineoverridevirtual

Reverts a change to the document. After undo() is called, the state of the document should be the same as before redo() was called. This function must be implemented in the derived class. Calling KUndo2QStack::push(), KUndo2QStack::undo() or KUndo2QStack::redo() from this function leads to undefined behavior.

The default implementation calls undo() on all child commands in reverse order.
