one or both of @a dx and @a dy are negative, the opposite happens: the

|

Inflating and deflating behaves "naturally". Defined more precisely,
|
||
|
that means:
|
||
|
-# "Real" inflates (that is, @a dx and/or @a dy = 0) are not
|
||
|
constrained. Thus inflating a rectangle can cause its upper left
|
||
|
corner to move into the negative numbers. (2.5.4 and older forced
|
||
|
the top left coordinate to not fall below (0, 0), which implied a
|
||
|
forced move of the rectangle.)
|
||
|
-# Deflates are clamped to not reduce the width or height of the
|
||
|
rectangle below zero. In such cases, the top-left corner is
|
||
|
nonetheless handled properly. For example, a rectangle at (10, 10)
|
||
|
with size (20, 40) that is inflated by (-15, -15) will become
|
||
|
located at (20, 25) at size (0, 10). Finally, observe that the width
|
||
|
and height are treated independently. In the above example, the
|
||
|
width is reduced by 20, whereas the height is reduced by the full 30
|
||
|
(rather than also stopping at 20, when the width reached zero).

/**
|
||
|
Creates a bitmap from either application resources or embedded image data
|
||
|
in PNG format.
|
||
|
|
||
|
This macro is similar to wxBITMAP() but works with bitmap data in PNG
|
||
|
format and not BMP or XPM.
|
||
|
|
||
|
Under Windows the given @a bitmapName must be present in the application
|
||
|
resource file with the type @c RCDATA and refer to a PNG image. I.e. you
|
||
|
should have a definition similar to the following in your @c .rc file:
|
||
|
@code
|
||
|
mybitmap RCDATA "mybitmap.png"
|
||
|
@endcode
|
||
|
to be able to use @c wxBITMAP_PNG(mybitmap) in the code.
|
||
|
|
||
|
Under OS X the file with the specified name and "png" extension must be
|
||
|
present in the "Resources" subdirectory of the application bundle.
|
||
|
|
||
|
Under the other platforms, this is equivalent to wxBITMAP_PNG_FROM_DATA()
|
||
|
and so loads the image data from the array called @c bitmapName_png that
|
||
|
must exist. Notice that it @e must be an array and not a pointer as the
|
||
|
macro needs to be able to determine its size. Such an array can be produced
|
||
|
by a number of conversion programs. A very simple one is included in
|
||
|
wxWidgets distribution as @c misc/scripts/png2c.py.
|
||
|
|
||
|
Finally notice that you must register PNG image handler to be able to
|
||
|
load bitmaps from PNG data. This can be done either by calling
|
||
|
wxInitAllImageHandlers() which also registers all the other image formats
|
||
|
or including the necessary header:
|
||
|
@code
|
||
|
#include <wx/imagpng.h>
|
||
|
@endcode
|
||
|
and calling
|
||
|
@code
|
||
|
wxImage::AddHandler(new wxPNGHandler);
|
||
|
@endcode
|
||
|
in your application startup code.

|
just the base name of the array containing the image data and computes its

size internally. In other words, the array called @c bitmapName_png must
