The attribute that will contain the resulting blob.
请注意,写作时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".
使用说明
- 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 thejpeg_compression_levelformat attribute. Consult the writer format documentation for a complete list of supported attributes.
- TheRasterReplacer.may be used to do the reverse operation and convert the encoded blob back to the original data.
- 或者,如果栅格不需要作为未来处理的特征的几何形状,则AttributeFileWriter变形金刚可用于将栅格Blob属性直接转换为文件。
- 要对矢量数据进行类似的操作,请使用Geometryextractor.transformer. For point cloud data, please use thepointcloudextractor..
