DocStr(wxImage,
"A platform-independent image class.  An image can be created from
data, or using `wx.Bitmap.ConvertToImage`, or loaded from a file in a
variety of formats.  Functions are available to set and get image
bits, so it can be used for basic image manipulation.

A wx.Image cannot be drawn directly to a `wx.DC`.  Instead, a
platform-specific `wx.Bitmap` object must be created from it using the
`wx.BitmapFromImage` constructor. This bitmap can then be drawn in a
device context, using `wx.DC.DrawBitmap`.

One colour value of the image may be used as a mask colour which will
lead to the automatic creation of a `wx.Mask` object associated to the
bitmap object.

wx.Image supports alpha channel data, that is in addition to a byte
for the red, green and blue colour components for each pixel it also
stores a byte representing the pixel opacity. An alpha value of 0
corresponds to a transparent pixel (null opacity) while a value of 255
means that the pixel is 100% opaque.

Unlike RGB data, not all images have an alpha channel and before using
`GetAlpha` you should check if this image contains an alpha channel
with `HasAlpha`. Note that currently only images loaded from PNG files
with transparency information will have an alpha channel.", "");

much nicer looking results it is a slower method.  Downsampling will
use the box averaging method which seems to operate very fast.  If you
are upsampling larger images using this method you will most likely
notice that it is a bit slower and in extreme cases it will be quite
substantially slower as the bicubic algorithm has to process a lot of
data.

It should also be noted that the high quality scaling may not work as
expected when using a single mask colour for transparency, as the
scaling will blur the image and will therefore remove the mask
partially. Using the alpha channel will work.

    Creates a `wx.Image` from the data in dataBuffer.  The dataBuffer
    parameter must be a Python object that implements the buffer interface,
    such as a string, array, etc.  The dataBuffer object is expected to
    contain a series of RGB bytes and be width*height*3 bytes long.  A buffer
    object can optionally be supplied for the image's alpha channel data, and
    it is expected to be width*height bytes long.

    The wx.Image will be created with its data and alpha pointers initialized
    to the memory address pointed to by the buffer objects, thus saving the
    time needed to copy the image data from the buffer object to the wx.Image.
    While this has advantages, it also has the shoot-yourself-in-the-foot
    risks associated with sharing a C pointer between two objects.

    To help alleviate the risk a reference to the data and alpha buffer
    objects are kept with the wx.Image, so that they won't get deleted until
    after the wx.Image is deleted.  However please be aware that it is not
    guaranteed that an object won't move its memory buffer to a new location
    when it needs to resize its contents.  If that happens then the wx.Image
    will end up referring to an invalid memory location and could cause the
    application to crash.  Therefore care should be taken to not manipulate
    the objects used for the data and alpha buffers in a way that would cause
    them to change size.
