在Linux下实现magnification功能

2003-12-17  Brian Cameron <[e-mail]>

	* magnifier/zoom-region.c:
	Now cache gc's, so there is less X-traffic.
	* magnifier/magnifier-main.c:
	Properly abort if user specifies a pantest but does not supply
	a number of iterations via --timing-iterations.  Corrected bug
	with exit-magnifier property not being set properly during the
	update test.

2003-12-11  Bill Haneman <[e-mail]>

	* magnifier/magnifier.c:
	Fixed compile issue in magnifier_expose_filter.
	Thanks to Kaushal Kumar for catching the problem.

2003-12-10  T脙碌ivo Leedj脙陇rv  <[e-mail]>

	* configure.in: Added et to ALL_LINGUAS.

2003-12-10  Bill Haneman <[e-mail]>

	* magnifier/zoom-region.c:
	(zoom_region_update): Changed use of deprecated
	gdk_pixbuf_render_to_drawable to
	gdk_draw_pixbuf.

	* magnifier/magnifier.c:
	(magnifier_transform_cursor): 
	Replaced gdk_pixbuf_render_to_drawable with gdk_draw_pixbuf (as above).

	* magnifier/magnifier-main.c, zoom-region.c, magnifier.c:
	Silenced some other compiler warnings introduced by timing patch.

2003-12-10  Bill Haneman <[e-mail]>

	* magnifier/zoom-region.c:
	Add #include <gdk/gdk.h>
	(zoom_region_clip_to_target): New function, clips a rectangle
	in the source screen to the zoom-region's target.  Used for 
	processing expose/dirty notifications on the source.
	(impl_zoom_region_mark_dirty): Fixed implementation; it was
	using the wrong coordinate system for the 'dirty' notification.

	* idl/GNOME_Magnifier.idl:
	Improved docs for markDirty.

	* magnifier/magnifier.c:
	(magnifier_expose_filter): New  method, filters
	'GdkExpose' events that are passed in on a source
	window for which notifications are selected by the 
	client.  Useful if we have the ability to 'snoop' exposes on 
	the source.
	(magnifier_set_expose_listener): 
	Add the expose filter (above) to a specified GdkWindow.
	(magnifier_realize): Add the expose filter (above) to the source root window
	on set_source_display.
	(impl_magnifier_add_zoom_region): Add the expose filter to the source
	root when the first zoom region is added.
	
2003-12-08  Brian Cameron <[e-mail]>
	* magnifier/zoom-region.c
	Cleaned the timing report, now more code reuse.

2003-12-09  脙聟smund Skj脙娄veland  <[e-mail]>

	* configure.in: Added nn to ALL_LNGUAS.
	* nn.po: Added Norwegian Nynorsk translation.

2003-12-09  Bill Haneman <[e-mail]>

	* configure,in, README, NEWS:
 	Version 0.10.4.

2003-12-08  Brian Cameron <[e-mail]>
	* magnifier/zoom-region.[ch]
	* magnifier/magnifier-mai.c
	Updated performance tests so that they work properly when 
	at magnification factors greater than 2.  Improved test so that
	the ROI never goes off the edge of the screen, and exits more
	cleanly.  Now display a performance summary so that performance
	data can be seen even if --timing-output is not specified.
	Improved the output so that it displays more useful information.
	Cleaned the implementation and code style.

2003-11-19  Brian Cameron <[e-mail]>

	* magnifier/zoom-region.c
	Made logic for computing total frame time more accurate, cleaned some
	printf statments, and added comments explaining how to read the timing
	report output.

2003-11-18  Brian Cameron <[e-mail]>

	* magnifier/zoom-region.c
	Fixed typo in printf statement.

2003-11-12  Brian Cameron <[e-mail]>

	* magnifier/magnifier-main.c
	* magnifier/zoom-region.c
	Updated panning test so that it loads the magnifier with
	screen data on first loop before starting the pan test.

2003-11-06  Brian Cameron <[e-mail]>

	* magnifier/zoom-region.h
	* magnifier/magnifier-main.c
	* magnifier/zoom-region.c
	Adding perfomance timing output.  Support two different types
	of tests (--timing-delta-x/y and --timing-pan-rate).  Now
	support pending of set_roi requests if they are coming in
	more quickly than can be processed.

2003-04-02  Bill Haneman <[e-mail]>

	[Bugs 106067, 105298, 105820]

	[Replaced use of deprecated methods gtk_signal_connect,
	gtk_exit, gtk_drawable_size, gtk_window_get_size.]

	* configure.in: Add -DG*_DISABLE_DEPRECATED to 
	GNOME_MAG_DEBUG_CFLAGS.

	* magnifier/Makefile.am:
	Add GNOME_MAG_DEBUG_CFLAGS to $INCLUDES
	(note that these CFLAGS don't include debug flags
	if --enable-debug wasn't specified).

	* test/mag-test.c:
	(magnifier_clear_all_regions): Removed (unused).
	(test_client_magnifier_get_zoomer): #ifdef'ed out (unused).
	
	* magnifier/magnifier-main.c:
	(main): Do popt stuff before calling gtk_init.
	Also, set $DISPLAY via putenv if it has been
	assigned via --target-display, this is because gtk+
	may not handle changing X servers mid-stream
	very well. 

	* magnifier/magnifier.h:
	* magnifier/magnifier.c:
	(magnifier_new): Don't pass argc and argv anymore, we
	weren't using them anyhow.

	* magnifier/zoom-region.c:
	(zoom_region_paint_crosswire_cursor):
	Fix broken calculation of clip bounds if we're clipping a
	crosswire cursor of thickness > 1 pixel about a cursor bitmap.
	
2003-04-02  Bill Haneman <[e-mail]>

        Fix for bugs 105205 and 106067.

	* magnifier/magnifier-main.c:
	(magnifier_options): Improved terse docs for --fullscreen,
	noting dependency on --source-display and --target-display.

	* configure.in: version 0.10.0
	
	* idl/GNOME_Magnifier.idl:
	(setMagFactor): return boolean instead of void,
	i.e. FALSE on failure.

	* magnifier/magnifier.h:
	(magnifier_error_check): New; test for X allocation errors.

	* magnifier/magnifier.c:
	(magnifier_error_check): New method (see above).
	(magnifier_x_error_handler): New method (see above).
	(magnifier_realize): Set X error handler (as above).

	* magnifier/zoom-region.h:
	* magnifier/zoom-region.c:
	(ZoomRegionPixmapCreationError): New enum.
	(zoom_region_paint_crosswire_cursor): 
	Initialize x_left_clip and y_top_clip.
	(zoom_region_create_pixmap): New, broken out from
	zoom_region_expose_handler.  
	Returns an error code if the pixmap could not be 
	created, for instance if the target drawable isn't 
	initialized yet, or we run out of X memory.
	(zoom_region_expose_handler): call create_pixmap (above),
	and decrement the scale factor if we can't allocate it.
	(impl_zoom_region_set_mag_factor): Refuse to comply, and
	return CORBA_FALSE, if the resulting pixmap is too big for
	X to allocate.  This also means we do the pixmap allocation
	synchronously now, so we can check.  
	Note that we can only check if the target is already in
	existance, so in some cases (setting the initial mag factor
	at magnifier startup, i.e. before it's mapped) we 
	won't actually return CORBA_FALSE, but will just create the
	largest pixmap possible once the target drawable is realized.

	(magnifier_get_root): New method.
	
	* magnifier/magnifier.c:
	(magnifier_get_root): New method.
	(magnifier_init_window): New method, initializes
	magnifier's main window.
	(magnifier_init): Call magnifier_init_window, don't
	try to set the magnifier's root window here anymore.
	Don't set source and target display to $DISPLAY here,
	set them also in magnifier_init_window.
	Initialize magnifier->priv->root to NULL and 
	set it on-demand.
	
	* magnifier/zoom-region.c:
	(zoom_region_scroll_smooth, zoom_region_cursor_rect): 
	(zoom_region_paint_cursor, zoom_region_paint_pixmap):

	null window, null cursor-backing-pixmap, etc.)

	Free new bonobo_args after use.
	(zoom_region_update_pointer, zoom_region_source_root):

	window with magnifier_get_root().
