| Inheritance Item object > BitmapItem object Availability Flash MX 2004. Description A BitmapItem object refers to a bitmap in the library of a document. The BitmapItem object is a subclass of the Item object (see Item object). Property summary for the BitmapItem object
In addition to the Item object properties, the BitmapItem object has following properties:
bitmapItem.allowSmoothing
Availability Flash MX 2004. Usage bitmapItem.allowSmoothing
Description Property; a Boolean value that specifies whether to allow smoothing of a bitmap (TRue) or not (false). Example The following code sets the allowSmoothing property of the first item in the library of the current document to TRue: fl.getDocumentDOM().library.items[0].allowSmoothing = true; alert(fl.getDocumentDOM().library.items[0].allowSmoothing); bitmapItem.compressionType
Availability Flash MX 2004. Usage bitmapItem.compressionType Description Property; a string that determines the type of image compression applied to the bitmap. Acceptable values are "photo" or "lossless". If the value of bitmapItem.useImportedJPEGQuality is false, "photo" corresponds to JPEG with a quality from 0 to 100; if bitmapItem.useImportedJPEGQuality is true, "photo" corresponds to JPEG using the default document quality value. The value "lossless" corresponds to GIF or PNG format. (See bitmapItem.useImportedJPEGQuality.) Example The following code sets the compressionType property of the first item in the library of the current document to "photo": fl.getDocumentDOM().library.items[0].compressionType = "photo"; alert(fl.getDocumentDOM().library.items[0].compressionType);
bitmapItem.quality
Availability Flash MX 2004. Usage bitmapItem.quality Description Property; an integer that specifies the quality of the bitmap. To use the default document quality, specify -1; otherwise, specify an integer from 0 to 100. Available only for JPEG compression. Example The following code sets the quality property of the first item in the library of the current document to 65: fl.getDocumentDOM().library.items[0].quality = 65; alert(fl.getDocumentDOM().library.items[0].quality); bitmapItem.useImportedJPEGQuality
Availability Flash MX 2004. Usage bitmapItem.useImportedJPEGQuality
Description Property; a Boolean value that specifies whether to use the default imported JPEG quality (true) or not (false). Available only for JPEG compression. Example The following code sets the useImportedJPEGQuality property of the first item in the library of the current document to true: fl.getDocumentDOM().library.items[0].useImportedJPEGQuality = true; alert(fl.getDocumentDOM().library.items[0].useImportedJPEGQuality);
