Window Leveling: Maps grayscale intensities using
a user defined color map (LUT).Programming with LEADTOOLS
Support for this control is provided by the LTIVW DLL. Each container created has both a window handle and a handle to the container itself. A container has a number of properties that govern the appearance of the container and the cells, including the number of rows and columns in which cells are viewed. The maximum number of rows and columns allowed in a container is 4 X 8. While a container can have a maximum of 4 rows and 8 columns, the number of cells in a container is limited by the amount of available memory.
A container, or Image Viewer, may contain a number of child windows called cells. These cells may contain images, tags or rulers. A cell can have one or more images attached to it. Cells may also contain rulers. In addition to images and rulers, cells may also contain tags.
Actions are processes that can be applied to the images attached to cells within the container/image viewer. LEADTOOLS supports several standard or "built-in" actions and custom or "user-defined" actions. The built-in actions LEADTOOLS supports are listed below:
Window Leveling: Maps grayscale intensities using
a user defined color map (LUT).
Alpha: A window-leveling factor used when the window
leveling lookup table is not linear.
Scale: Increases or decreases the size of the image
in the cell.
Offset: Changes the offset of the image within the
cell.
Magnifying Glass: Magnifies the image in the cell.
Stack: Scrolls the images within the cell.
Custom actions are completely controlled by the user, including any mouse movement and keystroke association.
