The Imaging Common Dialog libraries provide a set of common dialog boxes that combine Windows Common Dialog functionality with imaging functionality contained in LEADTOOLS. For a list of required DLLs, refer to Files To Be Included With Your Application. Imaging Common Dialogs are provided for numerous image processing, effects and filtering functions, and include the following features:
These dialogs provide input parameters needed for the several LEADTOOLS imaging functions. The table below gives the function that displays the dialog on the left and the image processing function associated with it on the right, if one exists. For more information on the Image Processing functions, refer to the LEADTOOLS Raster C++ Class Library help file in the LEADTOOLS/HELP directory.
In addition to the dialog functions provided for image processing, LEADTOOLS also provides Imaging Common Dialog functions for general use and dialog maintenance. These are given below.
Dialog Maintenance and General Use
Each of the XXXDoModalXXX functions listed above displays a dialog through which the user can enter parameters for various image processing or other functions. These dialogs may be initialized prior to calling the XXXDoModalXXX function by calling a corresponding GetXXXParams function. Likewise, once the user has made his or her selections in the dialog, those new values can be retrieved using a corresponding SetXXXParams function. The table below lists the corresponding GetXXXParams and SetXXXParams function for each DoModalXXX function listed above:
Implementing help for LEADTOOLS dialogs is achieved by setting a pointer to a help callback function in the structure passed to all functions in LDialogXXX classes. The callback function will be called to provide the appropriate help for the corresponding dialog if the user clicks on the Help Button. For more information concerning implementing the help callback function, refer to LDialogBase::DialogHelpCallBack Callback Function.
Supported Environments
The toolkit comes in Win32 and x64 editions. The environments supported depend upon the specific product, platform and function. For more information, refer to Supported Platforms / Operating Systems.
