Detailed Description

Finds the topmost image underneath the mouse pontier, cancel it's normal drawing, and then subtract it from the rest of the images.

It is meant to be the fast preview's equivalent of the accurate preview's difference mode.

Warning: Since the fast preview is approximate, this will show errors that don't really exist.

Member Function Documentation

void PreviewDifferenceTool::Activate ( )

virtual

Switch on a tool.

Inherited classes also register events they want to respond to with the PreviewToolHelper. As events are lost when the tool is deactivated without notification to the PreviewTool, things from the last activation can be cleaned up here too.

Implements Tool.

void PreviewDifferenceTool::AfterDrawImagesEvent ( )

virtual

Draw (using OpenGL) images above the others.

bool PreviewDifferenceTool::BeforeDrawImageEvent ( unsigned int image )

virtual

Draw what the tool requires just before a given image is drawn.

This can be used to modify how the images are drawn, prevent drawing of the image, or change the order of the image drawing (with another event to draw the image when it is needed).
