wxImage not works wxNativePixelData

[Alfresco]

Code: Select all

wxImagePanelAfter::wxImagePanelAfter(wxFrame* parent, wxImagePanel* pan):
    wxImagePanel(parent)
{
   bool t  =  image.Create(pan->width, pan->height);

....
t == true!

Code: Select all

void wxImagePanelAfter::keyPressed(wxKeyEvent& event)
    {
     wxNativePixelData data(image);

here stops and says that incorrect Bitmap type wxBitmapGetRawData()

So i used VS 2019 Comunity to compile wxwidgets 3

That is not surprising as wxNativePixelData works only with wxBitmaps without the alpha channel, as clearly stated in the docs. The wxImage in your code is automatically converted to wxBitmap, but that wxBitmap probably has the alpha channel.

Use wxImagePixelData with wxImage or use wxAlphaPixel data with a converted bitmap.
