Package er.attachment.thumbnail Description

ERAttachment Thumbnail (Image Processing Integration)

Overview

This package provides classes that wrap or integrate a number of popular image processing libraries. ERAttachment will just try and pick a suitable default, however you can specifically determine which image processing library is used with the property er.attachment.thumbnail.imageProcessor. Supported values for this property and corresponding libraries include:

sips

Commandline image processor available on Mac OS X

imageio

Mac OS X ImageIO and CoreImage libaries. Very fast.

imagemagick

The popular open source ImageMagick library. Probably the best option if you app is being deployed on a platform other than Mac OS X.

java

Java 2D. Probably the most compatible but the slowest option.

You can use these utilities directly yourself to resize image files:

        ERImageProcessor.imageProcessor().thumbnail( .... );
