contrib subdir 2000-10-06 Havoc Pennington <hp@redhat.com> * Makefile.am (SRC_SUBDIRS): contrib subdir * gdk/gdkpixbuf.h: Move GdkPixbufAlphaMode to gdk-pixbuf library, so it can be used in Xlib version * demos/testpixbuf.c (update_timeout): error checking from 1.0 tree * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_get_pixbuf): Sync change from 1.0 tree that returns first frame of animation if the loaded file is an animation. * contrib: add new directory to hold stuff that comes with GTK+ but isn't really part of GTK+ (for now, gdk-pixbuf-xlib) * configure.in: add contrib/* 2000-10-06 Havoc Pennington <hp@redhat.com> * gdk-pixbuf.h: add GdkPixbufAlphaMode 2000-10-06 Havoc Pennington <hp@redhat.com> This entry is a summary of the merged-in changes from 1.0. Relevant original ChangeLog entries are spliced in after this entry; the files they refer to are from the 1.0 gdk-pixbuf sources. * pixops/pixops.c (pixops_composite_nearest): sync a small fix from 1.0 * io-xpm.c (xpm_seek_string): add fscanf error check from 1.0 Add progressive loader from 1.0 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): mem leak fixes from 1.0 tree * io-pnm.c: new version from 1.0 tree * io-jpeg.c (gdk_pixbuf__jpeg_image_load): sync from 1.0, use malloc not g_malloc * io-gif.c (lzw_read_byte): sync from 1.0, change a g_error to g_warning (gif_get_next_step): return 0 here, sync from 1.0 * gdk-pixbuf-util.c: sync email address change for Cody Russell 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com> * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because last nights code was still "broken". Should now properly handle all error conditions gracefully. 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com> * gdk-pixbuf/io-pnm.c: Rewrote. 2000-09-09 Federico Mena Quintero <federico@helixcode.com> * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): Compute the correct dest offset. 2000-08-25 Federico Mena Quintero <federico@helixcode.com> * gdk-pixbuf/io-xpm.c: #include <unistd.h> 2000-08-05 Larry Ewing <lewing@helixcode.com> * gdk-pixbuf/io-tiff.c: stop leaking context->tempname. * gdk-pixbuf/io-xpm.c: same as above. 2000-07-26 Michael Meeks <michael@helixcode.com> * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_load): make g_malloc a malloc. 2000-07-21 Larry Ewing <lewing@helixcode.com> * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that xpm at least supports the progressive interface like the one in io-tiff.c. This should be reimplemented as an actual progressive loader. 2000-07-19 Jonathan Blandford <jrb@redhat.com> * demo/pixbuf-demo.c (update_timeout): changed scaling level to make it look better. * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael meeks to handle errors better.

Most of this patch is based on a patch by Havoc Pennington (hp@redhat.com) 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.

* Modifies saturation and optionally pixelates @src, placing the result in
* @dest. @src and @dest may be the same pixbuf with no ill effects. If
* @saturation is 1.0 then saturation is not changed. If it's less than 1.0,
* saturation is reduced (the image turns toward grayscale); if greater than

* is %TRUE, then pixels are faded in a checkerboard pattern to create a

/**
* gdk_pixbuf_apply_embedded_orientation:
* @src: A #GdkPixbuf.
*
* Takes an existing pixbuf and checks for the presence of an
* associated "orientation" option, which may be provided by the
* jpeg loader (which reads the exif orientation tag) or the
* tiff loader (which reads the tiff orientation tag, and
* compensates it for the partial transforms performed by
* libtiff). If an orientation option/tag is present, the
* appropriate transform will be performed so that the pixbuf
* is oriented correctly.
*
* Return value: A newly-created pixbuf, or a reference to the
* input pixbuf (with an increased reference count).
