Leadtools.Codecs Introduction

Summary

The Leadtools.Codecs namespace contains classes with properties, methods and events for loading, saving and converting any type of image file and for getting information about loaded bitmaps. These functions allow you to work with files in memory buffers or at offsets within disk files. Both high and low level functions are provided. It also contains classes that support loading/saving non-image data such as tags, markers, comments and extensions.

The RasterCodecs class is the main gateway to all file format features. Use it to load/save/convert images from disk or memory.

Key Features:

Get information about the image before loading it.
Handle file-format specific information, such as the page number or physical resolution.
Acquire low and high level handling of any feature. For example:
- Call a version of the RasterCodecs.Load overloaded method to load all the pages from a disk file into a RasterImage object.
- Use various low level events to monitor image scanlines as they are being loaded.
- Override the operation with your own data, or cancel it all together.
- Load/Save/Convert any type of image file.
