==========================================================================================================================================

A :class:`PyImageList` contains a list of images. Images can have masks for
transparent drawing, and can be made from a variety of sources including
bitmaps and icons.

:class:`PyImageList` is used in conjunction with :class:`UltimateListCtrl`.

:note: The main improvements that :class:`PyImageList` introduces is the removal
 of the limitation of same-size images inside the image list. If you use
 the style ``IL_VARIABLE_SIZE`` then each image can have any size (in terms
 of width and height).

===============


.. class:: PyImageList(object)

   A :class:`PyImageList` contains a list of images. Images can have masks for
   transparent drawing, and can be made from a variety of sources including
   bitmaps and icons.
   
   :class:`PyImageList` is used in conjunction with :class:`UltimateListCtrl`.
   
   :note: The main improvements that :class:`PyImageList` introduces is the removal
    of the limitation of same-size images inside the image list. If you use
    the style ``IL_VARIABLE_SIZE`` then each image can have any size (in terms
    of width and height).

   .. method:: __init__(self, width, height, mask=True, initialCount=1, style=IL_VARIABLE_SIZE)

      Default class constructor.
      
      :param `width`: the width of the images in the image list, in pixels (unused
       if you specify the ``IL_VARIABLE_SIZE`` style;
      :param `height`: the height of the images in the image list, in pixels (unused
       if you specify the ``IL_VARIABLE_SIZE`` style;
      :param `mask`: ``True`` if masks should be created for all images (unused in
       :class:`PyImageList`);
      :param `initialCount`: the initial size of the list (unused in :class:`PyImageList`);
      :param `style`: can be one of the following bits:
      
       ==================== ===== =================================
       Style Flag           Value Description
       ==================== ===== =================================
       ``IL_FIXED_SIZE``        0 All the images in :class:`PyImageList` have the same size (width, height)
       ``IL_VARIABLE_SIZE``     1 Each image can have any size (in terms of width and height)
       ==================== ===== =================================


   .. method:: Add(self, bitmap)

      Adds a new image or images using a bitmap.
      
      :param `bitmap`: a valid :class:`wx.Bitmap` object.
      
      :return: The new zero-based image index.
      
      :note: If the bitmap is wider than the images in the list and you are not using
       the ``IL_VARIABLE_SIZE`` style, then the bitmap will automatically be split
       into smaller images, each matching the dimensions of the image list.


   .. method:: AddIcon(self, icon)

      Adds a new image using an icon.
      
      :param `icon`: a valid :class:`Icon` object.
      
      :return: The new zero-based image index.
      
      :note: If the icon is wider than the images in the list and you are not using
       the ``IL_VARIABLE_SIZE`` style, then the icon will automatically be split
       into smaller images, each matching the dimensions of the image list.


   .. method:: AddWithColourMask(self, bitmap, maskColour)

      :note: If the bitmap is wider than the images in the list and you are not using
       the ``IL_VARIABLE_SIZE`` style, then the bitmap will automatically be split
       into smaller images, each matching the dimensions of the image list.
