Configuration
PagedTiffHandler rejects images based on error messages of ImageMagick. There are three options:


 * Images are rejected if the error message matches $wgTiffIdentifyRejectMessages
 * Images are accepted without moaning if the error message matches $wgTiffIdentifyBypassMessages
 * In other cases, images are accepted but the error message is recorded in the image metadata.

Example configuration (all of the parameters show the default configuration):

PagedTiffHandler depends on various external programs in order to process Tiff images.

For each software in use, a path to the binary file must be provided.
 * ImageMagick is used to check the image and render thumbail images. This is mandatory, PagedTiffHandler will not work without ImageMagick.
 * Exiv2 is used to extract image metadata (optional).
 * Vips is an addition to ImageMagick for fast processing of large image files (optional).

Example configuration:

PagedTiffHandler also checks a few parameters of the image in order to be able to control the necessary processing time.

Example configuration:
