Subject [jira] [Commented] (PDFBOX-4285) Expose the tiff compression type to the user.
Date Fri, 03 Aug 2018 11:21:00 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-4285?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16568108#comment-16568108

Alexandre Moraes do Nasciment commented on PDFBOX-4285:

Yes... i think that this approach would solve and make the tiff output more flexible.

I´ve tested using jpeg compression as default, and an image decreased from 11Mb to 2.5Mb
and same quality.

>             Project: PDFBox
>          Issue Type: Improvement
>          Components: Writing
>    Affects Versions: 2.0.11

>            Priority: Major
>              Labels: TIFF
> Allow the user to set the compression type of Tiff files externally.
> In the current version, the class ImageIOUtil uses TIFFUtil.setCompressionType and this
sets the compression only to "CCITT T.6" or "LZW". 
> Other choice could be allow the jpeg compression that is more efficient.
> It already has a TODO in code (// TODO expose this choice to the user?)
> Thank you.
