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.

This appendix describes the special options you can use while

|
compiling the <application>gdk-pixbuf</application> library.

<title>Building the Library</title>
|
|
<para>
|
|
The <application>gdk-pixbuf</application> library uses the
|
|
standard GNU build system, using
|
|
<application>autoconf</application> for package configuration
|
|
and resolving portability issues,
|
|
<application>automake</application> for building makefiles
|
|
that comply with the GNU Coding Standards, and
|
|
<application>libtool</application> for building shared
|
|
libraries on multiple platforms. The normal sequence for
|
|
compiling and installing the
|
|
<application>gdk-pixbuf</application> library is thus:
|
|
|
|
<literallayout>
|
|
<userinput>./configure</userinput>
|
|
<userinput>make</userinput>
|
|
<userinput>make install</userinput>
|
|
</literallayout>
|
|
</para>
|
|
|
|
<para>
|
|
The standard options provided by <application>GNU
|
|
autoconf</application> may be passed to the
|
|
<command>configure</command> script. Please see the
|
|
<application>autoconf</application> documentation or run
|
|
<command>./configure --help</command> for information about
|
|
the standard options.

<para>
|
|
In addition to the normal options, the
|
|
<command>configure</command> script in the
|
|
<application>gdk-pixbuf</application> library supports these
|
|
additional arguments:
|
|
|
|
<cmdsynopsis>
|
|
<command>configure</command>
|
|
|
|
<group>
|
|
<arg>--disable-modules</arg>
|
|
<arg>--enable-modules</arg>
|
|
</group>
|
|
|
|
<group>
|
|
<arg>--disable-gtk-doc</arg>
|
|
<arg>--enable-gtk-doc</arg>
|

</group>

</cmdsynopsis>

<formalpara>

<title><systemitem>--disable-modules</systemitem> and
|
|
<systemitem>--enable-modules</systemitem></title>
|
|
|
|
<para>
|
|
Normally <application>gdk-pixbuf</application> will try to
|
|
build the image file format loaders as little shared
|
|
libraries that are loaded on demand. The
|
|
<systemitem>--disable-modules</systemitem> argument
|
|
indicates that they should all be built statically into the
|
|
<application>gdk-pixbuf</application> library instead. This
|
|
is useful for people who need to produce statically-linked
|
|
binaries. If neither
|
|
<systemitem>--disable-modules</systemitem> nor
|
|
<systemitem>--enable-modules</systemitem> is specified, then
|
|
the <command>configure</command> script will try to
|
|
auto-detect whether shared modules work on your system.

|
|
|
|
<para>
|
|
By default the <command>configure</command> script will try
|
|
to auto-detect whether the
|
|
<application>gtk-doc</application> package is installed. If
|
|
it is, then it will use it to extract and build the
|
|
documentation for the <application>gdk-pixbuf</application>
|
|
library. These options can be used to explicitly control
|
|
whether gtk-doc should be used or not. If it is not used,
|
|
the distributed, pre-generated HTML files will be installed
|
|
instead of building them on your machine.
