2000-06-21 Havoc Pennington <hp@pobox.com> * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque (i.e. derivation is not allowed, and there are no virtual methods anyway). (gdk_pixbuf_preinit): Call g_type_init() here. (gdk_pixbuf_init): Add a user-friendly init function, for users of standalone gdk-pixbuf * gdk-pixbuf-animation.c: Convert to GObject, in the same way GdkPixbufAnimation was done. * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and gdk_pixbuf_finalize() from API, since these are broken and don't make sense with new GObject stuff. 2000-06-21 Havoc Pennington <hp@pobox.com> * gdk/gdkwindow.c (_gdk_window_destroy_hierarchy): Fix bug where we didn't check window->bg_pixmap != GDK_NO_BG. * gtk/gdk-pixbuf-loader.c: Change to reflect GObject-ification of gdk-pixbuf |

Your eyes are bloodshot.
Your eyes are bloodshot. Your mouth starts to foam. Your hands are shaking. You know your need your fix. NEED MORE ABSTRACTION! 2000-04-12 Federico Mena Quintero <federico@helixcode.com> This comes from an excellent idea by Tim Janik (timj@gtk.org) to hook to the last unref operation. * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New function to set the last unref handler for a pixbuf. (gdk_pixbuf_finalize): New function to actually finalize a pixbuf. It calls the pixbuf's destroy notification function and frees the GdkPixbuf structure itself. (gdk_pixbuf_unref): Use the last unref function of the pixbuf if available. * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields for the last unref handler and its user data. * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use g_new0() to allocate the pixbuf. * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): Fixed the call to gtk_signal_new() for the "frame_done" signal; it was not specifying the `frame' argument. * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_width): Fixed docstring. (gdk_pixbuf_animation_get_height): Likewise. (gdk_pixbuf_animation_get_num_frames): Likewise. (gdk_pixbuf_animation_get_frames): Likewise. * doc/gdk-pixbuf-sections.txt: Updated with the new functions and types. * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace. * doc/tmpl/scaling.sgml: Added the description for GdkInterpType. * doc/tmpl/refcounting.sgml: Updated with the information about the last unref handler. * doc/tmpl/*.sgml: Markup tweaks. * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh, update the libtool version number for libgnomecanvaspixbuf as well. (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned as well, or the old ones won't work with the new stuff. Also, renamed the modules as follows. * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the modules are called "libpixbufloader-<format>.so" instead of "libpixbuf-<format>.so". They needed renaming so that the new loaders won't overwrite the old ones; even with the versioning stuff, the new .so symlink to the .so.1.0.0 would overwrite the old real .so file. |

2000-04-11 Federico Mena Quintero <federico@helixcode.com> Most of this patch is based on a patch by Havoc Pennington (hp@redhat.com) to make GdkPixbuf's structures opaque and to remove the libart dependency. * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures. (GdkColorspace): New enum that for now only contains GDK_COLORSPACE_RGB. (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy notification function. (GdkInterpType): New num with interpolation types. * *.[ch]: Replace the libart stuff with our own stuff. * pixops/*.[ch]: Likewise. * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private declarations of the GdkPixbuf structures. * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf): Removed function. (gdk_pixbuf_get_format): Constify. (gdk_pixbuf_get_n_channels): Constify. (gdk_pixbuf_get_has_alpha): Constify. (gdk_pixbuf_get_bits_per_sample): Constify. (gdk_pixbuf_get_pixels): Constify. (gdk_pixbuf_get_width): Constify. (gdk_pixbuf_get_height): Constify. (gdk_pixbuf_get_rowstride): Constify. * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy a pixbuf. * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a bits_per_sample argument; currently only 8 bits per sample are supported. * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf): New accessor. (gdk_pixbuf_frame_get_x_offset): New accessor. (gdk_pixbuf_frame_get_y_offset): New accessor. (gdk_pixbuf_frame_get_delay_time): New accessor. (gdk_pixbuf_frame_get_action): New accessor. * gdk-pixbuf/gdk-pixbuf-render.c (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid mask rectangle for pixbufs without an alpha channel, set the *mask_return to NULL. * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify. * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes. * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some preconditions. Maybe we should also check for the colorspace, bits per pixel, and such. (gdk_pixbuf_composite): Likewise. (gdk_pixbuf_composite_color): Likewise. (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we cannot allocate the new pixbuf. (gdk_pixbuf_composite_color_simple): Likewise. * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer have an ArtPixBuf. * gdk-pixbuf/io-bmp.c: Fix includes. * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in an lvalue. * TODO: Populated. * configure.in: Removed checks for libart. * gdk-pixbuf/Makefile.am: Removed references to libart. (noinst_HEADERS): Added gdk-pixbuf-private.h. * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented the version number of the libtool library to indicate that this definitely is not compatible with the old usage. I know you love me. I know you do. * configure.in: Bumped version number to 0.7.0. * README: Updated. * gdk-pixbuf-config.in (--libs): We no longer require libart. * DEPENDS.libgdk_pixbuf: We no longer depend on libart. * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything. |
