Version 10
Version 10 is the first version of the LEADTOOLS Screen Capture C DLL.
Screen Capture capabilities becomes the 15th imaging technology category found in LEADTOOLS. New capture functions allow you to capture all or part of the screen into a bitmap. Capture the entire screen, active window, menu under cursor, window under cursor (button, tool bar, icon, or client area), selected object, mouse cursor or wallpaper. Allows for capture of a selected area of the screen in a wide array of shapes such as rectangle, rounded rectangle, ellipse, polygon or freehand. Icon, bitmap and cursor resources can be captured from 32-bit Windows EXE and DLL files. Options include Multi-capture with callback, Hot Keys, and time interval. Great for presentation and application documentation.
