Import Multipage Files plugin

Import Multipage Files plugin is required when running a batch on multipage images. This plugin will break the multipage .pdf and .tiff files into multiple single page .tiff files.

Multipage .pdf files will be converted to single page .tiff files using Ghostscript/Recostar.

Multipage .tiff files will be converted to single page .tiff files using ImageMagick/GraphicMagick.

Configuration

IMPORT_MULTIPAGE_FILES properties can be edited through Transact.

String

N/A

Parameters for Ghostscript command that should be used for multipage .pdf to multiple single page .tiff files conversion.

PDF To TIFF Conversion Process

List of values

  • Ghostscript
  • Recostar

.pdf to .tiff conversion process

Recostar Compression Ratio

List of values

  • 10
  • 20
  • 30
  • 40
  • 50
  • 60
  • 70

Compression ratio while converting .pdf to .tiff through Recostar

String

N/A

Input parameters for GraphicMagick image conversion process that should be used for multipage .tiff to multiple single page .tiff files conversion.

Optimized Tiff Conversion Switch

List of values

  • ON
  • OFF

If the switch is configured, the conversion and breaking into multipage single .tiff files is done irrespective of the size of the imported images via another utility - libtiff. It increases the overall processing time and reduces the size of the converted images (approximately similar to the input .tiff file).

Optimization parameters and results

-sDEVICE parameter

  • -sDEVICE=tiff12nc: Produces 12-bit RGB output.

  • -sDEVICE=tiff24nc: Produces 24-bit RGB output.

  • -sDEVICE=tiff48nc: Produces 48-bit RGB output.

  • -sDEVICE=tiff32nc: Produces 32-bit CMYK output

  • -sDEVICE=tiff64nc: Produces 64-bit CMYK output.

  • -sDEVICE=tiffscaled24 -sCompression=lzw: Produces a 24-bit RGB image and allows the use of a special compression tag along with it which allows us to compress the size of the image.

  • -sDEVICE=tifflzw: Produces black-and-white output and can be combined with various compression options.

Following are the results of images produced by splitting a PDF with the given specifications under different GhostScript parameters:

  • PDF Size: 514 KB

  • Number of pages in PDF: 26

PDF contains mixture of color and B/W images.

Troubleshooting

If a malfunction occurs with the Import Multipage Files plugin, the following errors may appear.

Error message

Possible root cause

Invalid property file configuration

The following properties in the <Transact-Installation-Path>/Application/WEB-INF/classes/META-INF/dcma-import-folder/dcma-import-folder.properties file are empty:

  • import.folder_ignore_char_list

  • import.ignore_replace_char

Converted .tiff files count not equal to the .tiff pages count.

The number of pages in .pdf/multipage .tiff is not equal to the converted .tiff files.
