The IDLanROI::RemoveData procedure method removes vertices from the region.
Syntax
Obj->[IDLanROI::]RemoveData[, COUNT=vertices] [, START=index] [, XRANGE=variable] [, YRANGE=variable] [, ZRANGE=variable]
Arguments
None.
Keywords
COUNT
Set this keyword to the number of vertices to remove. The default is one vertex.
START
Set this keyword to an index (into the region’s current vertex list) where the removal is to begin. By default, the final vertex is removed.
XRANGE
Set this keyword to a named variable that upon return contains a two-element vector, [xmin, xmax], that represents the X range of the modification to the region. The reported range accounts for the vertex just before the removal (if any), the vertex just after the removal (if any), and the removed vertices. This data is returned in double-precision floating-point.
YRANGE
Set this keyword to a named variable that upon return contains a two-element vector, [ymin, ymax], that represents the Y range of the modification to the region. The reported range accounts for the vertex just before the removal (if any), the vertex just after the removal (if any), and the removed vertices. This data is returned in double-precision floating-point.
ZRANGE
Set this keyword to a named variable that upon return contains a two-element vector, [zmin, zmax], that represents the Z range of the modification to the region. The reported range accounts for the vertex just before the removal (if any), the vertex just after the removal (if any), and the removed vertices. This data is returned in double-precision floating-point.
