Detailed Description
write polygonal data as a CGM file
vtkCGMWriter writes CGM (Computer Graphics Metafile) output. CGM is a 2D graphics vector format typically used by large plotters. This writer can handle vertices, lines, polygons, and triangle strips in any combination. Colors are specified either 1) from cell scalars (assumed to be RGB or RGBA color specification), 2) from a specified color; or 3) randomly assigned colors.
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.
- Warning:
- The class vtkImageToPolyDataFilter is convenient for converting a raster image into polygons (and color map) suitable for plotting with CGM.

Member Function Documentation
| static vtkCGMWriter* vtkCGMWriter::New | ( | ) | [static] |
Instantiate with no viewport defined and sorting on. The default resolution is 10,000, and the color mode is set to default.
Reimplemented from vtkPolyDataWriter.
| static int vtkCGMWriter::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkPolyDataWriter.
| virtual int vtkCGMWriter::IsA | ( | const char * | name | ) | [virtual] |
Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkPolyDataWriter.
| static vtkCGMWriter* vtkCGMWriter::SafeDownCast | ( | vtkObjectBase * | o | ) | [static] |
Reimplemented from vtkPolyDataWriter.
| virtual vtkObjectBase* vtkCGMWriter::NewInstanceInternal | ( | ) | const [protected, virtual] |
Reimplemented from vtkPolyDataWriter.
| vtkCGMWriter* vtkCGMWriter::NewInstance | ( | ) | const |
Reimplemented from vtkPolyDataWriter.
| void vtkCGMWriter::PrintSelf | ( | ostream & | os, |
| vtkIndent | indent | ||
| ) | [virtual] |
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkPolyDataWriter.
| virtual void vtkCGMWriter::SetViewport | ( | vtkViewport * | ) | [virtual] |
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.
| virtual vtkViewport* vtkCGMWriter::GetViewport | ( | ) | [virtual] |
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.
| virtual void vtkCGMWriter::SetSort | ( | int | ) | [virtual] |
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.
| virtual int vtkCGMWriter::GetSort | ( | ) | [virtual] |
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.
| virtual void vtkCGMWriter::SetResolution | ( | int | ) | [virtual] |
Specify the resolution of the CGM file. This number is used to integerize the maximum coordinate range of the plot file.
| virtual int vtkCGMWriter::GetResolution | ( | ) | [virtual] |
Specify the resolution of the CGM file. This number is used to integerize the maximum coordinate range of the plot file.
| virtual void vtkCGMWriter::SetColorMode | ( | int | ) | [virtual] |
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.
| virtual int vtkCGMWriter::GetColorMode | ( | ) | [virtual] |
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.
| void vtkCGMWriter::SetColorModeToDefault | ( | ) | [inline] |
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.
