/*
|
||||
* Determine the pixel dimensions of an image without actually
|
||||
* decoding the image. Passes an object of metadata to the callback
|
||||
* function on success or an error message to the error function on
|
||||
* failure. The metadata object will include type, width and height
|
||||
* properties. Supported image types are GIF, PNG and JPEG. JPEG
|
||||
* metadata may also include information about an EXIF preview image.
|
||||
*
|
||||
* Because of shortcomings in the way Gecko handles images, the
|
||||
* Gallery app will crash with an OOM error if it attempts to decode
|
||||
* and display an image that is too big. Images require 4 bytes per
|
||||
* pixel, so a 10 megapixel photograph requires 40 megabytes of image
|
||||
* memory. This function gives the gallery app a way to reject images
|
||||
* that are too large.
|
||||
*
|
||||
* Requires the BlobView class from shared/js/blobview.js and the
|
||||
* parseJPEGMetadata() function from shared/js/media/jpeg_metadata_parser.js
