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 8 X 8. While a container can have a maximum of 8 rows and 8 columns, the number of cells in a container is limited only by the amount of available memory.

A container, or Image Viewer, can contain a number of child windows called cells. These cells can contain images, tags or rulers. A cell can have one or more images attached to it. Cells can also contain rulers. In addition to images and rulers, cells can 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:

Annotations are based on vectored drawing functions and are associated with bitmaps as an overlay of the displayed image. Annotations are maintained separately from bitmaps. LEADTOOLS supports the following annotations:

A bitmap region is an area of interest within a bitmap. A region can be complex; including, for example, multiple noncontiguous shapes. LEADTOOLS supports the following types of regions:

Custom actions, including any mouse movement and keystroke associations, are completely controlled by the user.
