\remarks
|
This flag indicating that when applying transformation to the input points, output points
|
should be considered as 2d points, z-coordinate won't be used and does not require calculation.
|
|
This way could be used to avoid extra arithmetic operations on doubles.
|
|
An example of setOutput2dPoints() usage is GDI device implementation.
|
The last stage of geometry conveyor when playing metafiles to device is
|
OdGiXForm (metafile to device transformation). It produces points in pixel
|
coordinates, does not require z coordinate to be calculated.
