Member Function Documentation

extraPixels()

virtual uint ScalerPluginObject::extraPixels ( ) const

pure virtual

Indicates how far outside the scaling region this scaler "looks"

Returns

The number of pixels in any direction

canDrawCursor()

virtual bool ScalerPluginObject::canDrawCursor ( ) const

pure virtual

Some scalers are not suitable for scaling the cursor. Blurring scalers should return false.

getPrettyName()

virtual const char* ScalerPluginObject::getPrettyName ( ) const

pure virtual

This value will be displayed on the GUI.

getDefaultFactor()

virtual uint ScalerPluginObject::getDefaultFactor ( ) const

inlinevirtual

The default scale factor.

useOldSource()

virtual bool ScalerPluginObject::useOldSource ( ) const

inlinevirtual

Computationally intense scalers can benefit from comparing new and old source images and updating only the pixels necessary. If the function returns true, this scaler prefers this method and the backend can optionally use it.
