Introduction: DIBs, DDBs and the Clipboard
A DIB (device independent bitmap) is a standard Windows representation
of a bitmap. It is similar to the LEADTOOLS representation of a bitmap in
that it includes palette information. A DDB (device dependent bitmap) is a
hardware-specific representation that does not include palette information.
Sometimes, you may need to manipulate a bitmap using Windows functions that
work with DIBs or DDBs. For example, you may need to interact with an existing
application that uses those functions. For that purpose, LEADTOOLS functions
let you convert or copy to and from DIBs or DDBs.
The clipboard is a standard Windows object for copying data
from one application to another. LEADTOOLS lets you copy images to the clipboard
and paste images from the clipboard. When copying to the clipboard, most LEADTOOLS
functions clear the existing data from the clipboard, and copy image data
to it in the form of a DIB, a DDB, and a palette (if one is needed). If that
is not what you want, you can use a LEADTOOLS DLL function to specify exactly
which actions to take.
LEADTOOLS SDKs allow developers to add DIB and DDB support
to their applications quickly and easily. LEADTOOLS includes functions with
many options that give you the flexibility to make your images look as good
as possible. Whether you are working with medical
images, scanned
documents or digital
photographs, LEADTOOLS can help you provide the best representation of bitmap images in your applications.
