In particular, rename - libraries to lib*-3.0.so - pc files to *-3.0.pc - include paths to /usr/include/gtk-3.0/* - module paths to /usr/lib/gtk-3.0/* - rc files names to gtk-3.0/gtkrc - commandline utilities to *-3.0 - adjust documentation Also change the install location for unix-print headers to /usr/include/gtk-3.0/unix-print/gtk.

<para>

|
Pixmaps are offscreen drawables. They can be drawn upon with the
|
|
standard drawing primitives, then copied to another drawable (such as
|
|
a #GdkWindow) with gdk_pixmap_draw(). The depth of a pixmap
|
|
is the number of bits per pixels. Bitmaps are simply pixmaps
|
|
with a depth of 1. (That is, they are monochrome bitmaps - each
|
|
pixel can be either on or off).

<!-- ##### STRUCT GdkPixmap ##### -->
|
|
<para>
|
|
An opaque structure representing an offscreen drawable.
|
|
Pointers to structures of type #GdkPixmap, #GdkBitmap,
|
|
and #GdkWindow, can often be used interchangeably.
|
|
The type #GdkDrawable refers generically to any of
|
|
these types.

<!-- ##### FUNCTION gdk_pixmap_new ##### -->
|
|
<para>
|
|
Create a new pixmap with a given size and depth.
|
|
</para>
|
|
|
|
@drawable: A #GdkDrawable, used to determine default values
|
|
for the new pixmap. Can be %NULL if @depth is specified,
|
|
@width: The width of the new pixmap in pixels.
|
|
@height: The height of the new pixmap in pixels.
|
|
@depth: The depth (number of bits per pixel) of the new pixmap.
|
|
If -1, and @drawable is not %NULL, the depth of the new
|
|
pixmap will be equal to that of @drawable.
|
|
@Returns: the #GdkPixmap

</para>
|

|
@drawable: a #GdkDrawable, used to determine default values
|

for the new pixmap. Can be %NULL, in which case the root

window is used.
|
|
@data: a pointer to the XBM data.
|
|
@width: the width of the new pixmap in pixels.
|
|
@height: the height of the new pixmap in pixels.

@Returns: the #GdkBitmap

@drawable: a #GdkDrawable, used to determine default values
|
|
for the new pixmap. Can be %NULL, if the depth is given.
|

@data: a pointer to the data.
|
|
@width: the width of the new pixmap in pixels.
|
|
@height: the height of the new pixmap in pixels.
|

@depth: the depth (number of bits per pixel) of the new pixmap.
