Note: During output of the polygonal data, triangle strips are converted to triangles, and polylines to lines. Also, due to limitations in the CGM color model, only 256 colors are available to the color palette.
To create an instance of class vtkCGMWriter, simply invoke its constructor as follows
obj = vtkCGMWriter
obj
is an instance of the vtkCGMWriter class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkCGMWriter = obj.NewInstance ()
vtkCGMWriter = obj.SafeDownCast (vtkObject o)
obj.SetViewport (vtkViewport )
- Specify a vtkViewport object to be used to transform the vtkPolyData
points into 2D coordinates. By default (no vtkViewport specified), the
point coordinates are generated by ignoring the z values. If a viewport
is defined, then the points are transformed into viewport coordinates.
vtkViewport = obj.GetViewport ()
- Specify a vtkViewport object to be used to transform the vtkPolyData
points into 2D coordinates. By default (no vtkViewport specified), the
point coordinates are generated by ignoring the z values. If a viewport
is defined, then the points are transformed into viewport coordinates.
obj.SetSort (int )
- Turn on/off the sorting of the cells via depth. If enabled, polygonal
cells will be sorted from back to front, i.e., a Painter's algorithm
sort.
int = obj.GetSort ()
- Turn on/off the sorting of the cells via depth. If enabled, polygonal
cells will be sorted from back to front, i.e., a Painter's algorithm
sort.
obj.SetResolution (int )
- Specify the resolution of the CGM file. This number is used to integerize
the maximum coordinate range of the plot file.
int = obj.GetResolutionMinValue ()
- Specify the resolution of the CGM file. This number is used to integerize
the maximum coordinate range of the plot file.
int = obj.GetResolutionMaxValue ()
- Specify the resolution of the CGM file. This number is used to integerize
the maximum coordinate range of the plot file.
int = obj.GetResolution ()
- Specify the resolution of the CGM file. This number is used to integerize
the maximum coordinate range of the plot file.
obj.SetColorMode (int )
- Control how output polydata is colored. By default (ColorModeToDefault),
if per cell colors are defined (unsigned chars of 1-4 components), then
the cells are colored with these values. (If point colors are defined
and cell colors are not, you can use vtkPointDataToCellData to convert
the point colors to cell colors.) Otherwise, by default, the cells are
set to the specified color. If ColorModeToSpecifiedColor is set, then
the primitives will all be set to this color. If ColorModeToRandomColors
is set, each cell will be randomly assigned a color.
int = obj.GetColorMode ()
- Control how output polydata is colored. By default (ColorModeToDefault),
if per cell colors are defined (unsigned chars of 1-4 components), then
the cells are colored with these values. (If point colors are defined
and cell colors are not, you can use vtkPointDataToCellData to convert
the point colors to cell colors.) Otherwise, by default, the cells are
set to the specified color. If ColorModeToSpecifiedColor is set, then
the primitives will all be set to this color. If ColorModeToRandomColors
is set, each cell will be randomly assigned a color.
obj.SetColorModeToDefault ()
- Control how output polydata is colored. By default (ColorModeToDefault),
if per cell colors are defined (unsigned chars of 1-4 components), then
the cells are colored with these values. (If point colors are defined
and cell colors are not, you can use vtkPointDataToCellData to convert
the point colors to cell colors.) Otherwise, by default, the cells are
set to the specified color. If ColorModeToSpecifiedColor is set, then
the primitives will all be set to this color. If ColorModeToRandomColors
is set, each cell will be randomly assigned a color.
obj.SetColorModeToSpecifiedColor ()
- Control how output polydata is colored. By default (ColorModeToDefault),
if per cell colors are defined (unsigned chars of 1-4 components), then
the cells are colored with these values. (If point colors are defined
and cell colors are not, you can use vtkPointDataToCellData to convert
the point colors to cell colors.) Otherwise, by default, the cells are
set to the specified color. If ColorModeToSpecifiedColor is set, then
the primitives will all be set to this color. If ColorModeToRandomColors
is set, each cell will be randomly assigned a color.
obj.SetColorModeToRandomColors ()
- Control how output polydata is colored. By default (ColorModeToDefault),
if per cell colors are defined (unsigned chars of 1-4 components), then
the cells are colored with these values. (If point colors are defined
and cell colors are not, you can use vtkPointDataToCellData to convert
the point colors to cell colors.) Otherwise, by default, the cells are
set to the specified color. If ColorModeToSpecifiedColor is set, then
the primitives will all be set to this color. If ColorModeToRandomColors
is set, each cell will be randomly assigned a color.
obj.SetSpecifiedColor (float , float , float )
- Set/Get the specified color to color the polydata cells. This
color is only used when the color mode is set to
ColorModeToSpecifiedColor, or ColorModeToDefault is set and no
cell colors are specified. The specified color is specified as RGB
values ranging from (0,1). (Note: CGM will map this color to the
closest color it supports.)
obj.SetSpecifiedColor (float a[3])
- Set/Get the specified color to color the polydata cells. This
color is only used when the color mode is set to
ColorModeToSpecifiedColor, or ColorModeToDefault is set and no
cell colors are specified. The specified color is specified as RGB
values ranging from (0,1). (Note: CGM will map this color to the
closest color it supports.)
float = obj. GetSpecifiedColor ()
- Set/Get the specified color to color the polydata cells. This
color is only used when the color mode is set to
ColorModeToSpecifiedColor, or ColorModeToDefault is set and no
cell colors are specified. The specified color is specified as RGB
values ranging from (0,1). (Note: CGM will map this color to the
closest color it supports.)
