This code creates a wxBitmap object from a PNG image file. The second argument specifies the file type. Package library: wxWidgets 2. Creating a bitmap from an array of image data:c++
This code creates a wxBitmap object from an array of RGB pixel data. The last argument specifies the number of bits per pixel. Package library: wxWidgets 3. Drawing a bitmap on a wxPanel:c++ class MyPanel : public wxPanel { public: MyPanel(wxWindow* parent) : wxPanel(parent) {} void OnPaint(wxPaintEvent& event) { wxPaintDC dc(this); wxBitmap bitmap("image.png", wxBITMAP_TYPE_PNG); dc.DrawBitmap(bitmap, 0, 0); } wxDECLARE_EVENT_TABLE(); }; wxBEGIN_EVENT_TABLE(MyPanel, wxPanel) EVT_PAINT(MyPanel::OnPaint) wxEND_EVENT_TABLE() ``` This code creates a custom wxPanel class and overrides its OnPaint method to draw a bitmap on it using a wxPaintDC object. The wxDECLARE_EVENT_TABLE and wxBEGIN_EVENT_TABLE macros are used to associate the event handler with the panel. Package library: wxWidgets
