Generate
random data
DSpGMIdentity:
DSpGMCreateRandomBand
In this operation a new band is added to a raster, and every pixel is assigned a random value. The newly added band is of type dspRasterBandContinuous and has a default NULL value. The band must be of type dspUInt32 or dspFloat32. In the first case a random value between 0 and $7FFFFFFF is generated, in the latter case a value between 0 and 1.
procedure DSpGMCreateRandomBand(const r: TDSpRaster; const token: integer;
datatype: TDSpDataType);
| Parameter | Description |
| r | A valid raster object. It must be opened for write access. |
| token | The access token for the raster. The token has to be generated for write access. |
| datatype | The data type of the raster band that will be generated. The value of this parameter must be dspUInt32 or dspFloat32. |
