Right-click for contextual menu access. Move and size the window to the desired location, and select the "Capture" command for a region capture of the screen, or the "Full Screen" command for a full capture of the screen. Save the capture with the "Save" command; png format (by default) gives a perfect result. The "Clear" command erases the capture.

You can easily capture and manipulate a screen portion, e.g., compare two texts or two images.
The "Show All" command shows the full menu and all commands.

The "Thumbnail..." command allows you to save a thumbnail (or a enlargement) of the capture (with 2 methods). Image effects (Lighten, Darken, GrayScale, Invert, Contrast, Color, RGB ...) and special effects (Selective GrayScale, Color To Transparent, Psychedelic, B/W Sketch, Color Emboss...) are available with the "Effects" menu. Multi-level Undo and Redo are also available.

By double-click, if CaptureScreen is your image editor by default, you can open and edit images and saved captures. In "More Commands" menu, you can use the "Open and Mix" or the "Capture and Mix" commands, to mix and merge images and captures.

The "Transparent Mode" command preserves the window and the image in transparency: you can use the capture like a tracing paper. The "No Border Mode" command allows you to hide window's border; you can open by example several instances of CaptureScreen to make a photomontage. All image effects are available in a selection rectangle with the "Selection Mode".

The "CaptureScreen Options" allows you to set and save user settings (Hotkeys for menus commands, Run in "No Border Mode", Transparency, Delay Time, JPG Quality...). The "JPG Quality" Options allows you to reduce the file size of the image (saved in JPG/JPEG format). Settings and are also automatically saved to a text file, when closing the application.

- "Selective GrayScale", "Color To Transparent" and "Selective Transparent" effects: select a color by double-clicking on the captured image. These effects are inactive with a stretched image (large image or full screen captured). For the "Color To Transparent" and "Selective Transparent effects", you need to open an image of the same size that the capture to fill transparent areas.

- The "Effects Settings..." menu allows you to set parameters for most of the images effects. Under category "Convolution Effects", you will find predefined effects (Emboss, Sharpening, Edge Detect, Blur...). You can also create and save your own effects using a "Convolution Matrix" (see "B/W...Emboss" tab).

- To open a image with CaptureScreen, use the "Open" menu (Ctrl+O), or right-click on the image file(ex: .jpg file), use the classic "Open With" Dialog Box (Open With / Choose default program...), browse and select "CaptureScreen.exe". To always open this image file with CaptureScreen, check "Always use the selected program to open this kind of file".
