|phoenix_title|  **wx.Image**
==========================================================================================================================================

This class encapsulates a platform-independent image.          

An image can be created from data, or using :meth:`wx.Bitmap.ConvertToImage` . An image can be loaded from a file in a variety of formats, and is extensible to new formats via image format handlers. Functions are available to set and get image bits, so it can be used for basic image manipulation. 

A :ref:`wx.Image`  cannot (currently) be drawn directly to a :ref:`wx.DC`. Instead, a platform-specific :ref:`wx.Bitmap`  object must be created from it using the `Bitmap.Bitmap(wxImage,int` depth) constructor. This bitmap can then be drawn in a device context, using :meth:`wx.DC.DrawBitmap` . 

More on the difference between :ref:`wx.Image`  and :ref:`wx.Bitmap`: :ref:`wx.Image`  is just a buffer of ``RGB`` bytes with an optional buffer for the alpha bytes. It is all generic, platform independent and image file format independent code. It includes generic code for scaling, resizing, clipping, and other manipulations of the image data. OTOH, :ref:`wx.Bitmap`  is intended to be a wrapper of whatever is the native image format that is quickest/easiest to draw to a DC or to be the target of the drawing operations performed on a :ref:`wx.MemoryDC`. By splitting the responsibilities between Image/wxBitmap like this then it's easier to use generic code shared by all platforms and image types for generic operations and platform specific code where performance or compatibility is needed. 

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



|phoenix_title| Alpha channel support
=====================================

Starting from wxWidgets 2.5.0 :ref:`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. The constants ``IMAGE_ALPHA_TRANSPARENT``  and ``IMAGE_ALPHA_OPAQUE``  can be used to indicate those values in a more readable form. While all images have ``RGB`` data, not all images have an alpha channel. Before using :meth:`wx.Image.GetAlpha`   you should check if this image contains an alpha channel with :meth:`wx.Image.HasAlpha` . Currently the ``BMP``, ``PNG``, ``TGA``, and ``TIFF`` format handlers have full alpha channel support for loading so if you want to use alpha you have to use one of these formats. If you initialize the image alpha channel yourself using :meth:`wx.Image.SetAlpha` , you should save it in either ``PNG``, ``TGA``, or ``TIFF`` format to avoid losing it as these are the only handlers that currently support saving with alpha.  



|phoenix_title| Available image handlers
========================================

The following image handlers are available. BMPHandler is always installed by default. To use other image formats, install the appropriate handler with :meth:`wx.Image.AddHandler`   or call :ref:`wx.InitAllImageHandlers`. 

- BMPHandler: For loading (including alpha support) and saving, always installed. 
- :ref:`wx.PNGHandler`: For loading and saving. Includes alpha support. 
- :ref:`wx.JPEGHandler`: For loading and saving. 
- :ref:`wx.GIFHandler`: For loading and saving (see below). 
- :ref:`wx.PCXHandler`: For loading and saving (see below). 
- :ref:`wx.PNMHandler`: For loading and saving (see below). 
- :ref:`wx.TIFFHandler`: For loading and saving. Includes alpha support. 
- :ref:`wx.TGAHandler`: For loading and saving. Includes alpha support. 
- :ref:`wx.IFFHandler`: For loading only. 
- :ref:`wx.XPMHandler`: For loading and saving. 
- ICOHandler: For loading and saving. 
- CURHandler: For loading and saving. 
- ANIHandler: For loading only. 


When saving in ``PCX`` format, :ref:`wx.PCXHandler`  will count the number of different colours in the image; if there are 256 or less colours, it will save as 8 bit, else it will save as 24 bit. Loading PNMs only works for ``ASCII`` or raw ``RGB`` images. When saving in ``PNM`` format, :ref:`wx.PNMHandler`  will always save as raw ``RGB``. Saving GIFs requires images of maximum 8 bpp (see :ref:`Quantize`), and the alpha channel converted to a mask (see :meth:`wx.Image.ConvertAlphaToMask` ). Saving an animated ``GIF`` requires images of the same size (see :meth:`wx.GIFHandler.SaveAnimation` )

      :param `name`: Name of the file from which to load the image.   
      :type `name`: string
      :param `type`: May be one of the following: 
      
       - ``wx.BITMAP_TYPE_BMP``: Load a Windows bitmap file.  
       - ``wx.BITMAP_TYPE_GIF``: Load a ``GIF`` bitmap file.

   .. staticmethod:: AddHandler(handler)

      Register an image handler.                  

      Typical example of use: ::

                      wx.Image.AddHandler(wx.PNGHandler)



      See :ref:`Available image handlers <wx.Image>`  for a list of the available handlers. You can also use :ref:`wx.InitAllImageHandlers`  to add handlers for all the image formats supported by wxWidgets at once. 




      :param `handler`: A heap-allocated handler object which will be deleted by :ref:`wx.Image`  if it is removed later by :meth:`RemoveHandler`   or at program shutdown.   
      :type `handler`: wx.ImageHandler




                  





   .. method:: AdjustChannels(self, factor_red, factor_green, factor_blue, factor_alpha=1.0)

                      a factor (around 1.0). Useful for gamma correction, colour correction
                      and to add a certain amount of transparency to a image (fade in fade
                      out effects). If factor_alpha is given but the original image has no
                      alpha channel then a alpha channel will be added.

      **ConvertAlphaToMask** `(self, threshold=IMAGE_ALPHA_THRESHOLD)`
      
      If the image has alpha channel, this method converts it to mask.                  
      
      If the image has an alpha channel, all pixels with alpha value less than `threshold`  are replaced with the mask colour and the alpha channel is removed. Otherwise nothing is done. 
      
      The mask colour is chosen automatically using :meth:`FindFirstUnusedColour`   by this function, see the overload below if you this is not appropriate.

      Options specific to
      :ref:`wx.GIFHandler`: 

      -  ``IMAGE_OPTION_GIF_COMMENT:``   The comment text that is read from or written to the ``GIF`` file. In an animated ``GIF`` each frame can have its own comment. If there is only a comment in the first frame of a ``GIF`` it will not be repeated in other frames. 





      :param `name`: The name of the option, case-insensitive.   
      :type `name`: string






      :rtype: `string`



                  



      :returns: 

         The value of the option or an empty string if not found. Use :meth:`HasOption`   if an empty string can be a valid option value.  







      .. seealso:: :meth:`SetOption` , :meth:`GetOptionInt` , :meth:`HasOption`     








   .. method:: GetOptionInt(self, name)

      Gets a user-defined integer-valued option.                  

      The function is case-insensitive to `name`. If the given option is not present, the function returns 0. Use :meth:`HasOption`   if 0 is a possibly valid value for the option. 

      Generic options: 

      -  ``IMAGE_OPTION_MAX_WIDTH``   and   ``IMAGE_OPTION_MAX_HEIGHT:``   If either of these options is specified, the loaded image will be scaled down (preserving its aspect ratio) so that its width is less than the max width given if it is not 0  `and`  its height is less than the max height given if it is not 0. This is typically used for loading thumbnails and the advantage of using these options compared to calling :meth:`Rescale`   after loading is that some handlers (only ``JPEG`` one right now) support rescaling the image during loading which is vastly more efficient than loading the entire huge image and rescaling it later (if these options are not supported by the handler, this is still what happens however). These options must be set before calling :meth:`LoadFile`   to have any effect. 




      -  ``IMAGE_OPTION_ORIGINAL_WIDTH``   and   ``IMAGE_OPTION_ORIGINAL_HEIGHT:``   These options will return the original size of the image if either   ``IMAGE_OPTION_MAX_WIDTH``   or   ``IMAGE_OPTION_MAX_HEIGHT``   is specified.  

        .. versionadded:: 2.9.3 
    


      -  ``IMAGE_OPTION_QUALITY:``   ``JPEG`` quality used when saving. This is an integer in 0..100 range with 0 meaning very poor and 100 excellent (but very badly compressed). This option is currently ignored for the other formats. 




      -  ``IMAGE_OPTION_RESOLUTIONUNIT:``   The value of this option determines whether the resolution of the image is specified in centimetres or inches, see ImageResolution enum elements. 




      -  ``IMAGE_OPTION_RESOLUTION`` ,   ``IMAGE_OPTION_RESOLUTIONX``   and   ``IMAGE_OPTION_RESOLUTIONY:``   These options define the resolution of the image in the units corresponding to   ``IMAGE_OPTION_RESOLUTIONUNIT``   options value. The first option can be set before saving the image to set both horizontal and vertical resolution to the same value. The X and Y options are set by the image handlers if they support the image resolution (currently ``BMP``, ``JPEG`` and ``TIFF`` handlers do) and the image provides the resolution information and can be queried after loading the image. 

      Options specific to
      :ref:`wx.PNGHandler`: 

      -  ``IMAGE_OPTION_PNG_FORMAT:``   Format for saving a ``PNG`` file, see ImagePNGType for the supported values.   
      -  ``IMAGE_OPTION_PNG_BITDEPTH:``   Bit depth for every channel (R/G/B/A).   
      -  ``IMAGE_OPTION_PNG_FILTER:``   Filter for saving a ``PNG`` file, see libpng (`http://www.libpng.org/pub/png/libpng-1.2.5-manual.html <http://www.libpng.org/pub/png/libpng-1.2.5-manual.html>`_) for possible values (e.g. ``PNG_FILTER_NONE``, ``PNG_FILTER_SUB``, ``PNG_FILTER_UP``, etc).  
      -  ``IMAGE_OPTION_PNG_COMPRESSION_LEVEL:``   Compression level (0..9) for saving a ``PNG`` file. An high value creates smaller-but-slower ``PNG`` file. Note that unlike other formats (e.g. ``JPEG``) the ``PNG`` format is always lossless and thus this compression level doesn't tradeoff the image quality.   
      -  ``IMAGE_OPTION_PNG_COMPRESSION_MEM_LEVEL:``   Compression memory usage level (1..9) for saving a ``PNG`` file. An high value means the saving process consumes more memory, but may create smaller ``PNG`` file.   
      -  ``IMAGE_OPTION_PNG_COMPRESSION_STRATEGY:``   Possible values are 0 for default strategy, 1 for filter, and 2 for Huffman-only. You can use OptiPNG (`http://optipng.sourceforge.net/ <http://optipng.sourceforge.net/>`_) to get a suitable value for your application.  
      -  ``IMAGE_OPTION_PNG_COMPRESSION_BUFFER_SIZE:``   Internal buffer size (in bytes) for saving a ``PNG`` file. Ideally this should be as big as the resulting ``PNG`` file. Use this option if your application produces images with small size variation. 

      Options specific to
      :ref:`wx.TIFFHandler`: 

      -  ``IMAGE_OPTION_TIFF_BITSPERSAMPLE:``   Number of bits per sample (channel). Currently values of 1 and 8 are supported. A value of 1 results in a black and white image. A value of 8 (the default) can mean greyscale or ``RGB``, depending on the value of   ``IMAGE_OPTION_TIFF_SAMPLESPERPIXEL`` .   
      -  ``IMAGE_OPTION_TIFF_SAMPLESPERPIXEL:``   Number of samples (channels) per pixel. Currently values of 1 and 3 are supported. A value of 1 results in either a greyscale (by default) or black and white image, depending on the value of   ``IMAGE_OPTION_TIFF_BITSPERSAMPLE`` . A value of 3 (the default) will result in an ``RGB`` image.   
      -  ``IMAGE_OPTION_TIFF_COMPRESSION:``   Compression type. By default it is set to 1 (``COMPRESSION_NONE``). Typical other values are 5 (``COMPRESSION_LZW``) and 7 (``COMPRESSION_JPEG``). See tiff.h for more options.   
      -  ``IMAGE_OPTION_TIFF_PHOTOMETRIC:``   Specifies the photometric interpretation. By default it is set to 2 (``PHOTOMETRIC_RGB``) for ``RGB`` images and 0 (``PHOTOMETRIC_MINISWHITE``) for greyscale or black and white images. It can also be set to 1 (``PHOTOMETRIC_MINISBLACK``) to treat the lowest value as black and highest as white. If you want a greyscale image it is also sufficient to only specify   ``IMAGE_OPTION_TIFF_PHOTOMETRIC``   and set it to either ``PHOTOMETRIC_MINISWHITE`` or ``PHOTOMETRIC_MINISBLACK``. The other values are taken care of.

   .. method:: Scale(self, width, height, quality=IMAGE_QUALITY_NORMAL)

      Returns a scaled version of the image.                  

      This is also useful for scaling bitmaps in general as the only other way to scale bitmaps is to blit a :ref:`wx.MemoryDC`  into another :ref:`wx.MemoryDC`. 

      The parameter `quality`  determines what method to use for resampling the image, see ImageResizeQuality documentation. 

      It should be noted that although using  ``IMAGE_QUALITY_HIGH``   produces 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. 

      Example: ::

                  # get the bitmap from somewhere
                  bmp = wx.Bitmap('my_png.png', wx.BITMAP_TYPE_PNG)

                  # rescale it to have size of 32*32
                  if bmp.GetWidth() != 32 or bmp.GetHeight() != 32:

                      image = bmp.ConvertToImage()
                      bmp = wx.Bitmap(image.Scale(32, 32))

                      # another possibility:
                      image.Rescale(32, 32)
                      bmp = wx.Bitmap(image)

      Sets the alpha value for the given pixel.                  
      
      This function should only be called if the image has alpha channel data, use :meth:`HasAlpha`   to check for this.

      **SetAlpha** `(self, alpha)`
      
      This function is similar to :meth:`SetData`   and has similar restrictions.                  
      
      The pointer passed to it may however be ``None`` in which case the function will allocate the alpha array internally  
      
      If the pointer is not ``None``, it must have one byte for each image pixel and be allocated with malloc(). :ref:`wx.Image`  takes ownership of the pointer and will free it unless `static_data`  parameter is set to ``True``

      The data given must have the size (widthheight3) or results will be unexpected. Don't use this method if you aren't sure you know what you are doing. 
      
      The data must have been allocated with  ``malloc()`` ,  **NOT**  with  ``operator``   new.

   .. method:: SetMaskFromImage(self, mask, mr, mg, mb)

      Sets image's mask so that the pixels that have ``RGB`` value of mr,mg,mb in mask will be masked in the image.                  

      This is done by first finding an unused colour in the image, setting this colour as the mask colour and then using this colour to draw all pixels in the image who corresponding pixel in mask has given ``RGB`` value. 

      The parameter `mask`  is the mask image to extract mask shape from. It must have the same dimensions as the image. 

      The parameters `mr`, `mg`, `mb`  are the ``RGB`` values of the pixels in mask that will be used to create the mask.

      The image is pasted into a new image with the given `size`  and background colour at the position `pos`  relative to the upper left of the new image. 

      If `red`  = green = blue = -1 then the areas of the larger image not covered by this image are made transparent by filling them with the image mask colour (which will be allocated automatically if it isn't currently set).
