The module also defines a new input filter called flash that you can use. This lets you re-use Flash content in other nodes by using the format [flash|nid=<nid>] in the body of a node. You can pass optional parameters to manipulate the display of the Flash content by including them in the macro. Allowable parameters are:

• width - set a specific width, in pixels
• height - set a specific height, in pixels
• scale - scale both width and height to a multiple of the original size
• xscale - scale just the width to a multiple of the original size
• yscale - scale just the height to a multiple of the original size
• scalewidth - set a specific width, in pixels, and automatically adjust the height to maintain the aspect ratio
• scaleheight - set a specific height, in pixels, and automatically adjust the width to maintain the aspect ratio
• class - create the container div with a specific CSS class (the default class is flash)

Flash content is inserted using the method that you specify in SWFTools.'); } } /** * Implementation of hook_node_info */ function flashnode_node_info() { return array( 'flashnode' => array( 'name' => t('Flash'), 'module' => 'flashnode', 'description' => t('Allows you to easily upload and display a Flash file.
