Serializes the geometry of the feature into the Blob Attribute based on the selected writer format.
Parameters
Format
The raster format used to encode the blob.
Format Name Attribute
An attribute to preserve the specified format value for future use.
Blob Attribute
The attribute that will contain the resulting blob.
Note that when writing the Blob Attribute, you may need to adjust the attribute type to an unbounded data type to avoid truncation of the blob.
Please choose an appropriate attribute type depending on the destination format. For example, an appropriate attribute type for SQL Server is "image".
Usage Notes
- Writer parameters may be controlled by setting format attributes on the feature. For example, when writing to JPEG, the compression level may be set via the jpeg_compression_level format attribute. Consult the writer format documentation for a complete list of supported attributes.
- The RasterReplacer may be used to do the reverse operation and convert the encoded blob back to the original data.
- Alternatively if the raster is not required as a geometry on the feature for future processing, the AttributeFileWriter transformer can be used to dump the Raster Blob Attribute directly to a file.
- To carry out a similar operation on vector data, please use the GeometryExtractor transformer. For point cloud data, please use the PointCloudExtractor.
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.
