QGIS Algorithm provided by QGIS (native c++) Extract binary field (native:extractbinary). This algorithm extracts contents from a binary field, saving them to individual files. This algorithm extracts contents from a binary field, saving them to individual files. Filenames can be generated using values taken from an attribute in the source table or based on a more complex expression.
