LWW GDI Package

Wade Humeniu #1 / 4	LWW GDI Package I sent some code to Rafael Len. It is the start of a LWW extension to the Window's GDI interface. I just thought since it is gathering dust that it would not be lost. It extends some functionality that is not in CAPI/GP. The file is at http://www.--.com/ There is also a test file for bitmaps, I forget if it all works or not. http://www.--.com/ Example of its uses CAPIGDI 60 > (setf pane (capi:contain (make-instance 'capi:output-pane :min-width 200 :min-height 200))) #<CAPI:OUTPUT-PANE 21673C6C> CAPIGDI 61 > (setf pixmap-port (gp:create-pixmap-port pane 200 200 :clear t :background :black)) #<GRAPHICS-PORTS:PIXMAP-PORT 21674674> CAPIGDI 62 > (gp:draw-rectangle pixmap-port 10 10 50 50 :background :white :foreground :white :filled t) T CAPIGDI 63 > (winapi::\|BitBlt\| (hdc pane) 0 0 200 200 (hdc pixmap-port) 0 0 winapi::SRCCOPY) T CAPIGDI 64 > Wade

Yes it should. The problem that Rafael was experiencing was that the LWW pixblt was doing the same thing for any operation. He ended up using winapi::\|BitBlt\| with winapi::SRCINVERT to do what he needed. I suggested to Rafael that he might put in a bug report but he wanted it quickly. I am sure the operation parameter worked before, but for some reason it does not anymore. Wade

This has been fixed in the latest version. -- Martin Simmons, Xanalys Software Tools rot13 to reply
