Version 5.1 of VintaSoftImaging.NET SDK has been released.

What's new in this version of VintaSoftImaging.NET SDK:
  • ImageViewer and AnnotationViewer revised:
    • Display and work with large images (gigapixel):
      • No need to store all image in memory.
      • Progressive image loading in viewer (for JPEG2000, BMP, TIFF).
      • Image loading by parts in viewer (for JPEG2000, JPEG, BMP, TIFF).
      • Uses multithreading in work with large images.
    • Increased image scrolling speed.
    • The ability to set the anchor of image location in viewer.
    • The ability to set image focus point:
      • Fixed focus point: is set by anchor on visible part of image.
      • Nonfixed focus point: adds the ability to get back the viewed part of image while zooming.
    • The ability to programmatically move to the specified point on the image in viewer.
    • The ability to zoom relative to the specified point on the image.
    • More accurate zoom - ZoomExtended which allows values from 0.01 to 1000 percent.
    • Display special image map for fast navigation along the large image with following features:
      • Image map size and location anchor in viewer.
      • Relative zoom or BestFit mode.
      • Highlighting of current visible image area.
      • Changeover to the specified place on the image by mouse click on map.
  • Enhanced abilities of working with BMP, JPEG, JPEG2000 and TIFF decoders:
    • The ability to get a part of image in specified scale without decoding and loading whole image into memory.
    • The ability to gain different parts of the same image in different threads (multithreading).
  • New ImageRenderer Class provides rich functionality to work with large and very large (gigapixel) images:
    • The ability to gain specified part of image in specified scale.
    • Displays intermediate steps of image acquisition (smooth loading).
    • Progressive multistage loading of image or its part (JPEG2000, BMP, TIFF)
    • Fast getting thumbnails without loading whole image into memory (JPEG2000, JPEG, BMP, TIFF, PNG).
    • Uses multithreading while getting image or its part (thread count can be either chosen automatically or set manualy).
    • Cashes already loaded parts of image for better performance.
  • Codecs
    • PNG codec created:
      • Decoding of 1/2/4/8/16/24/32/48/64-bit images.
      • Encoding of 1/4/8/16/24/32/48/64-bit images.
      • Increase in compression of PNG files up to 40%.
      • Set image compression level and applicable data filter.
      • Add/read text data fields in PNG file.
      • Change palette and resolution without rewriting whole file.
    • TIFF codec improved:
      • Added BigTIFF image support.
      • Added the ability to get a part of TIFF file page.
      • Added the ability to get scaled image page of TIFF file.
      • Optimized work with TIFF file metadata. Created algorithm which optimizes (minimizes) metadata size of TIFF file page.
      • Added CIELab color space support.
  • Visual Tools
    • Added new visual tool ScrollPages: scroll images via mouse weel and jump from one to another when reaching the bottom.
    • Improved zoom step calculating algorithm for better visual sensing in visual tool Zoom.
    • Improved zooming algorithm in visual tool Zoom - it zooms now relative to zoom point specified by mouse click.
    • Improved image quality in visual tool Magnifier.
  • Demos
    • Created new demo Large Image Viewer Demo.
    • MultiPageTiffDemo:
      • Added the ability to set format and version for created TIFF file.
      • Added the ability to load BigTIFF files.
    • Added dialog box for ImageViewer and ThubnailViewer properties editing.

  • Optimized memory usage while encoding multipage JBIG2 files.
  • Optimized encoding in lossless mode:
    • Speed increase 3%.
    • File size decrease 2% at the average.
    • Optimized memory usage.
  • Improved algorithm of adding symbols to symbol dictionary in lossy encoding mode.
  • Optimized encoding in lossy mode:
    • Speed increase 30%.
    • Optimized quality of outgoing image (fewer inaccurate symbol substitutions, table destructions etc).
    • Optimized memory usage.
  • Optimized JBIG2 decoder algorithm (speed increase 3%).
  • Fixed few minor bugs in decoder and encoder.
What's new in this version of VintaSoftJPEG2000.NET Plug-in:
  • Added the ability to display very large (gigapixel) JPEG 2000 images using progressive multithreaded loading of image by parts.
  • Added the ability to get an image tile with specified decomposition level (scale).
  • Added the ability to get rectangular area of an image tile (also in case only one tile present in the image) with specified decomposition level (scale).
