RasterNumericCreator
Creates a feature with a raster of the specified size with a numeric value and sends it into the workspace for processing. It is useful for creating a very large image with a user-specified width and height.
Parameters
Raster Properties
When specifying the size of the output raster, either the desired dimensions or the desired extents can be provided. The choice you make here will determine which additional parameters are enabled in the transformer.
To set the output raster size using dimensions, set this parameter to RowsColumns.
To set the output raster size using extents, set this parameter to Extents.
These parameters specify the number of columns and rows the raster will have. This must be at least one.
The X Cell Origin and Y Cell Origin parameters specify the origin for each cell. This can be used to specify whether each cell's data point is at the lower-left or center (or somewhere else) within the cell.
These parameters specify the spacing between cell elements. This must be greater than zero.
The parameters specify the origin for the upper-left corner of the raster as a whole.
These parameters specify the origin for the lower-right corner of the raster as a whole.
This parameter specifies the rotation of the raster.
Interpretation
This parameter sets the type of data stored at each cell in the raster and number of bits used for that type.
Data Values
The parameters specify the range of values each cell in the raster can take.
The parameter specifies the nodata value (0-1) for this raster.
This parameter specifies which type of raster should be created:
- Single Value means each cell in the raster will be set to the maximum raster value.
- Checkered Pattern means alternating cells in the raster will be set to values between the minimum and maximum raster values.
- Checkerboard means alternating blocks of data in the raster will be set to the minimum and maximum raster values, in a standard eight-by-eight checkerboard pattern. The sizes of these blocks of data are variable, and dependent on the number of rows and columns specified. If the number of rows and columns are not multiples of eight, the remaining data will be set to either nodata values or the minimum value.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
