The image parser can be used for a comparison of images. Is especially useful in combination with optical character recognition features.
The parser supports the formats: PNG, JPG, JPEG, GIF and BMP.
To open multi page image documents, the images can be compressed into a ZIP archive. The parser will then open the pages in the order they were stored in the archive. The name of the images in the ZIP archive does not affect the order of the pages.
To scale the images on screen the DPI entry of the meta data of the images is used. If the image does not provide such information the 'Default image DPI' value of the server configuration will be used instead.
This value is 300 DPI by default since 300 DPI are the usual resolution for fax or scans.
