### QPx_NewImporterForURL

QPx_NewImporterForURL(importerRef; imageURL):error
| importerRef | Longint | New graphics importer reference
| imageURL | Text | URL to the image
| error | Longint | Error result

Creates a graphics importer instance for the image stored at the specified URL and returns a reference to this importer instance. This reference is used with all QPix commands in this group to refer to the graphics importer instance and to its associated data. QuickTime 4.0 supports the http://, ftp://, and file:// URL schemes.

The reference to the importer instance is returned in the importerRef parameter. QPix calls QuickTime to identify the image and create an instance of the proper graphics importer. QuickTime iterates over all available importers, checking the importer type and flags, until it finds an importer that can handle the specified graphics file. If the specified file format is not supported by any importer, importerRef is set to 0 and the qpx_paramErr error code is returned.

If imageURL is empty, QPix presents a URL selection dialog where the user can type or paste a URL, or select a recently visited URL from a popup menu. If the user provides a URL, it is returned in imageURL. If the user cancels the dialog, error qpx_userCancelErr is returned.
