PDB equivalence

A table of old PDB calls, and their equivalents in the PIKA 3.0+ world.

This document is a work in progress. Feel free to add to it.

Undo/Context

Removed function	Replacement
pika_undo_push_group_start	image.undo_group_start()
pika_undo_push_group_end	image.undo_group_end()
pika.context_push()	Pika.context_push()
pika.context_push()	Pika.context_push()
pika_context_get_background	Pika.context_get_background
pika_context_set_background	Pika.context_set_background

File load/save

Removed function	Replacement
pika_file_load	Pika.file_load
pika_file_save	Pika.file_save

Selection operations

Selection operations are now in the Pika.Selection class (except a few in the Image class). E.g.

Removed function	Replacement
pdb.pika_selection_invert(img)	Pika.Selection.invert(img)
pdb.pika_selection_none(img)	Pika.Selection.none(img)
pdb.pika_selection_layer_alpha(layer)	img.select_item(Pika.ChannelOps.REPLACE, layer)
pika_image_select_item	img.select_item(channel_op, layer)

Filling and Masks

Removed function	Replacement
Pika.drawable_fill()	layer.fill()
pdb.pika_edit_fill(FILL_BACKGROUND)	layer.edit_fill(Pika.FillType.BACKGROUND)
pika_layer_add_mask	layer.add_mask
pika_layer_remove_mask	layer.remove_mask

Miscellaneous and Non-PDB Calls

Removed function	Replacement
pika_displays_flush	Pika.displays_flush
pika_image_insert_layer	image.insert_layer

Plug-ins

Calling other plug-ins is trickier than before. The old

pdb.script_fu_drop_shadow(img, layer, -3, -3, blur,
                              (0, 0, 0), 80.0, False)

becomes

        c = Pika.RGB()
        c.set(240.0, 180.0, 70.0)
        Pika.get_pdb().run_procedure('script-fu-drop-shadow',
                                     [ Pika.RunMode.NONINTERACTIVE,
                                       GObject.Value(Pika.Image, img),
                                       GObject.Value(Pika.Drawable, layer),
                                       GObject.Value(GObject.TYPE_DOUBLE, -3),
                                       GObject.Value(GObject.TYPE_DOUBLE, -3),
                                       GObject.Value(GObject.TYPE_DOUBLE,blur),
                                       c,
                                       GObject.Value(GObject.TYPE_DOUBLE, 80.0),
                                       GObject.Value(GObject.TYPE_BOOLEAN, False)
                                     ])
