MediaViewers tiff conversion #99

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Current mediaviewer plugin converts tiff to pdf but does not work for  large 
tiff files. Need quicker conversion for large tiff files or fall back to 
flashviewer.

firebug reports errors in firefox

Have you got a good example file which reproduces this issue? If so could you 
attach it to this ticket?

The Media Viewers config does not explicitly configure TIFF > PDF 
transformations, instead the underlying transformers configured within the 
repository are used for this.

If you have a better transformation engine for converting TIFF files and you 
configure it in the repository, then the viewer should automatically use that. 
Note that some of the options around transformers are changing in 4.2 - see 
http://blogs.alfresco.com/wp/wabson/2013/07/09/changes-to-transformers-configura
tion-in-alfresco-4-2/.

The only change that could be made to the viewer is to add a maximum file size, 
beyond which the preview will fall back to another viewer as you suggest. I 
have opened a new issue on GitHub to track this - 
https://github.com/share-extras/media-viewers/issues/16.

I am closing this issue as NotABug, since the issue does not really lie here.
