Leadtools.ImageProcessing.Kernel Introduction

Summary

The Leadtools.ImageProcessing.Kernel assembly contains classes and functions used in image processing. The basic functions included are related to changing the appearance of the image in a bitmap.

In addition, the functions in this assembly have been optimized to run on mobile devices. These functions can check the quality of a frame and determine whether the quality is good enough for the frame to be saved. It also includes post-processing functions, including cropping or deskewing. Such commands can be placed in a list in order to perform a specific sequence of operations upon the images.

Key Features

• Change the appearance of the image in a bitmap:

  • Copy an image.
  • Crop an image.
  • Invert an image.
  • Correct an image's perspective.
  • Change the orientation by flipping the image horizontally or vertically.

• Image Information:

  • Determine the signal to noise ratio.
  • Detect glare.
  • Detect a document's boundaries.

Note: All RasterCommands in this assembly modify the underlying properties of the input RasterImage, including but not limited to:

• BitsPerPixel
• Data
• IsMirrored

To avoid RasterImage property fidelity loss, pass a clone of your RasterImage to all RasterCommands in this assembly.

LEADTOOLS Image Processing Features

LEADTOOLS Image Processing includes over 200 functions, some of which are typically found only in high performance end-user programs such as Adobe PhotoShop®. The image processing functions are separated into four categories: Transforms, Filters, Color Conversion and Drawing. Additionally, LEADTOOLS image processing functions support regions of interest, allowing only a specified region of an image to be processed.
