Detailed Description

This control displays an 8-bit indexed color image (called label map), overlayed with an anti-aliased full-color image.

The indexed colors denote regions in the image and the user can get notified when the mouse moves from region to region and change the colors used for the indices freely. This can be used to display, e.g., a color-coded schematic map of organs, floor plans.

This control also supports auto-highlighting of regions (by lightening/darkening colors when the mouse is over a region), smooth scaling of the images and pre-defined color tables.

Member Function Documentation

highestRegionIndex

int MLABImageMapControl::highestRegionIndex ( ) const

slot

Returns the highest available label index.

labelColor

unsigned int MLABImageMapControl::labelColor ( int  index ) const

slot

Returns the entry of the current color table.

setFixedScaleFactor

void MLABImageMapControl::setFixedScaleFactor ( double  factor )

slot

Sets a fixed scaling factor.

setLabelColor

void MLABImageMapControl::setLabelColor ( int  index, const QVariant &  color  )

slot

Sets a single label color.

setLabelColors

void MLABImageMapControl::setLabelColors ( const QVariantList &  colors )

slot

Sets multiple label colors (starting with index 0).

setLabelMap

void MLABImageMapControl::setLabelMap ( const QString &  filename )

slot

Sets a new label map image that needs to be a 8-bit indexed color image.

This will reset all previously set label colors and replace them with the colors from the image.

setOverlay

void MLABImageMapControl::setOverlay ( const QString &  filename )

slot

Sets a new overlay image.

unsetFixedScaleFactor

void MLABImageMapControl::unsetFixedScaleFactor ( )

slot

Unsets the fixed scaling factor.
