Request.Operation.Output
Output file path.
For non-spreadsheet files, the output file name must include the ${Number} or ${Page} parameter. If there are multiple output files, ${Number} indicates that serial numbers start from 1, and ${Page} indicates that serial numbers are the same as preview page numbers.
${Number} indicates that serial numbers start from 1 for multiple output files; for example, if the input parameter is abc_${Number}.jpg to preview pages 5–6 in the file, then output file names will be abc_1.jpg and abc_2.jpg.
${Page} indicates that serial numbers are the same as preview page numbers for multiple output files; for example, if the input parameter is abc_${Page}.jpg to preview pages 5–6 in the file, then the output file names will be abc_5.jpg and abc_6.jpg.
For spreadsheet files, the output file path must include the ${SheetID} placeholder, and the output file name must include the ${Number} parameter.
For example, if the input parameter is /${SheetID}/abc_${Number}.jpg, then the corresponding number of folders will be generated first according to the number of Excel sheets to be converted, and then the corresponding number of image files will be generated in these folders.
