Detailed Description

An image collection can hold multiple images, created from an image file.

ImageCollection()

Create an empty image collection, which can have Image objects added to it.

ImageCollection(Imageimage)

Parameters

image: Image: the Image object to be inserted upon creation.

Create a new image collection containing the supplied Image object.

ImageCollection(stringfileName)

Parameters

fileName: string: The physical image file from which an image collection will be created.

Create from an image file. If the file is a TIFF, then an Image object will be created for each "page" of the TIFF. For all other types, only 1 Image object will be created.

ImageCollection(stringfileName, Documentdocument)

Parameters

fileName: string: The physical image file from which an image collection will be created.
document: Document: the document in which the image is intended to be used.

Create from an image file. If the file is a TIFF, then an Image object will be created for each "page" of the TIFF.

For all other types, only 1 Image object will be created.

Specifying the document optimizes data usage for this image within that document.

ImageCollection(System.IO.Streamstream)

Parameters

stream: System.IO.Stream: The Stream from which to read the ImageCollection.

Create an ImageCollection from a Stream.

This allows an ImageCollection to be read from a Stream object. The Stream must be seekable. Suitable examples are FileStream and MemoryStream. The Stream must contain image data in the TIFF Format.

ImageCollection(System.IO.Streamstream, Documentdocument)

Parameters

stream: System.IO.Stream: The Stream from which to read the ImageCollection.
document: Document: The Document in which the ImageCollection is intended to be used.
