Hi, I'm trying to implement fpimage support in the fpGUI widget framework. I'm really confused at the moment. :) The following queries apply to X11 (xlib) only. My GDI (windows) support will come later.
My current BMP image implementation (which doesn't use the fpimage unit) has an internal TXImage. One for the Mask and one for the Image Data. Now creating a descendant of TFPCustomImage, I know I need to implement the following two methods. procedure SetInternalPixel(x, y: integer; Value: integer); override; function GetInternalPixel(x, y: integer): integer; override; 1) Those are the only abstract methods. So where am I supposed to create the instance of TXImage and assign it the internal data? When am I supposed to assign the internal data? 2) Am I supposed to descend from TFPCustomImage or TFPMemoryImage? What's the difference?
