How do I do this in Delphi...
Posted on 2000-04-02
I've loaded a JPG into TImage. What I need to do now is, like the rectangle area selection function in PaintBrush(of Windows 9x), where user press the mouse button at a point, move the mouse to a final point, release the button and a dashed line rectangle should appear at the area.
Then, what I need to do with this area is: Cut the area when user press the 'D' key so that the area which the user selected will be a white area, and this area has been copied to an invisible TImage for some other purpose.
I have look at some similar codes in C++ but was unable to translate them into Delphi.
Can anyone help me here?! Thanks.
