Package com.google.appengine.api.images Description

This package provides facilities for the creation and manipulation of images by Java code. The starting point is the ImagesServiceFactory class, which can produce the ImageService, but also the basic Image object and Transform classes. More information is available in the on-line documentation.

Image data is represented as a byte[] of data, in any of the supported formats: JPEG, PNG, GIF (including animated GIF), BMP, TIFF, and ICO formats. The format can be accessed via the Image#getFormat method. The image format may be converted during transformation.

Supported transformations include cropping, resizing, rotating in 90-degree increments, horizontal and vertical flips, and automated color enhancement.
