       Prima::ImageDialog - file open and save dialogs.


       The module provides dialogs specially adjusted for image loading and


       Provides a preview feature, allowing the user to view the image file
       before loading, and the selection of a frame index for the multi-framed
       image files.  Instead of "execute" call, the load method is used to
       invoke the dialog and returns the loaded image as a "Prima::Image"
       object.  The loaded object by default contains "{extras}" hash variable
       set, which contains extra information returned by the loader. See
       Prima::image-load for more information.

               my $dlg = Prima::ImageOpenDialog-> create;
               my $img = $dlg-> load;
               return unless $img;
               print "$_:$img->{extras}->{$_}\n" for sort keys %{$img-> {extras}};

       preview BOOLEAN
           Selects if the preview functionality is active.  The user can
           switch it on and off interactively.

           Default value: 1

       load %PROFILE
           Executes the dialog, and, if successful, loads the image file and
           frame selected by the user. Returns the loaded image as a
           "Prima::Image" object.  PROFILE is a hash, passed to
           "Prima::Image::load" method. In particular, it can be used to
           disable the default loading of extra information in "{extras}"
           variable, or to specify a non-default loading option.  For example,
           "{extras}->{className} = 'Prima::Icon'" would return the loaded
           image as an icon object. See Prima::image-load for more.

           "load" can report progressive image loading to the caller, and/or
           to an instance of "Prima::ImageViewer", if desired. If either (or
           both) "onHeaderReady" and "onDataReady" notifications are
           specified, these are called from the respective event handlers of
           the image being loaded ( see "Loading with progress indicator" in
           Prima::image-load for details).  If profile key "progressViewer" is
           supplied, its value is treated as a "Prima::ImageViewer" instance,
           and it is used to display image loading progress. See
           "watch_load_progress" in Prima::ImageViewer.

       HeaderReady IMAGE
           See "HeaderReady" in Prima::Image.

       DataReady IMAGE, X, Y, WIDTH, HEIGHT
           See "DataReady" in Prima::Image.


       Provides a save dialog where the user can select image format, the bit
       depth and other format-specific options. The format-specific options
       can be set if a dialog for the file format is provided.  The standard
       toolkit dialogs reside under in "Prima::Image" namespace, in
       Prima/Image subdirectory. For example, "Prima::Image::gif" provides the
       selection of transparency color, and "Prima::Image::jpeg" the image
       quality control. If the image passed to the image property contains
       "{extras}" variable, the data are read and used as the default values.
       In particular, "{extras}->-{codecID}" field, responsible for the file
       format, if present, affects the default file format selection.

               my $dlg = Prima::ImageSaveDialog-> create;
               return unless $dlg-> save( $image );
               print "saved as ", $dlg-> fileName, "\n";

       image IMAGE
           Selects the image to be saved. This property is to be used for the
           standard invocation of dialog, via "execute". It is not needed when
           the execution and saving is invoked via save method.

       save IMAGE, %PROFILE
           Invokes the dialog, and, if the execution was successful, saves the
           IMAGE according to the user selection and PROFILE hash.  PROFILE is
           not used for the default options, but is passed directly to
           "Prima::Image::save" call, possibly overriding selection of the
           user.  Returns 1 in case of success, 0 in case of error.  If the
           error occurs, the user is notified before the method returns.
