What's New in GrapeCity Documents v5.2

Overview

A .NET image API library is a programming interface that allows developers to programmatically create and manipulate images at scale. GrapeCity Documents for Imaging is a solution allowing developers to load, process, and save images across many different formats in desktop and web-based applications.

Fast and Efficient

Save memory with the small file size and time with the lightweight API architecture. Scalable, flexible, efficient, and fast to handle small and large TIFFs at top speed.

Image Processor

Meet all the needs of a basic image processor: resize, convert, rotate, and flip images. Create, apply, and align the images in your apps that you need when you need them.

Advanced Image Effects

Convert average images into high-quality, detailed images in less time. Apply advanced image effects like dithering, thresholding effects, half-tone transparencies, resolution editing, grayscale conversion, effects on RGB images, and more.

Text and Graphics

Dynamically enhance your images with logos and text. With extensive font, layout, and graphic support, you can convert your images into branding elements and professional pages.

Full .NET Core Support

Develop for any .NET platform or major operating system like Windows, Linux, and Mac with a single code base. Use in your apps for .NET Core, .NET Framework, Mono, Xamarin.iOS, and Xamarin.Android.

Image Processing to the Cloud

Be everywhere with cloud-based deployment. With NuGet and GcImaging, you can deploy to Azure, AWS, and AWS Lambda to create services that manage and convert images on the cloud.

Image Comparison

Compare images for software testing, image manipulation detection, or comparing shots from security frames. Perform fuzzy image comparisons and generate different images. This tool provides an effective way of comparing a variety of image types.

Render Special CJK Characters

Render specific CJK characters on images with advanced support. Special TrueType features such as hinting are used to re-use glyph parts for drawing CJK characters on images.

Import HTML into Your Images

  • Render HTML string, URL, or pages in Images
  • Based on a Chromium web browser engine working in headless mode
  • Multi-platform package to render HTML content on Windows, macOS or Linux

Manage Profile Photos in Your Apps

  • Convert to grayscale or sepia
  • Apply effects to TIFF images
  • Resize and crop images
  • Export to popular image formats
  • Add a round clip to images

Handle Images on Any Device or System

  • Dither high-color depth images to view on low-color depth environments
  • Select from eight different dithering effects
  • Apply to any image format
