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.

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. OTOH, 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 wx.MemoryDC. It includes generic code for scaling, resizing, clipping, and other manipulations of the image data. It is all generic, platform independent and image file format independent code. More on the difference between wx.Image and wx.Bitmap: wx.Image is just a buffer of RGB bytes with an optional buffer for the alpha bytes. This bitmap can then be drawn in a device context, using wx.DC.DrawBitmap. Instead, a platform-specific wx.Bitmap object must be created from it using the Bitmap.Bitmap(wxImage,int depth) constructor.
Functions are available to set and get image bits, so it can be used for basic image manipulation.Ī wx.Image cannot (currently) be drawn directly to a wx.DC. An image can be loaded from a file in a variety of formats, and is extensible to new formats via image format handlers. This class encapsulates a platform-independent image.Īn image can be created from data, or using wx.Bitmap.ConvertToImage.
