Product and Development Musings

ImageMan.Net Version 2.09 is available

4. March 2011 06:08

The next release of our ImageMan.Net components is now available for downloading. The installation can be downloaded from the My Products page or from the Trial Downloads page.

Among the enhancements and bug fixes are:

  • Faster PDF Import support in the PDFDecoder class. The memory usage was also reduced particularly helping when importing files with a large number of pages.
  • Performance improvements when reducing the bit depth depth of images to 1 bit using the ModifyBitdepthCommand class.
  • Fixes to a couple of small memory leaks in the PDF & TIFF Decoder/Encoder classes. In a long running service type application these could cause problems so its important to update if you have any longer running applications.
  • Fixed a slow startup issue on a few machines that was caused by the RSACrypto code used in our licensing.
  • A host of other minor updates which can be found in the release notes on the My Products page.

ImageMan.Net Twain Version 3 is now shipping

10. January 2011 07:33

The next release of our ImageMan.Net Twain toolkit is now available for downloading. Despite the major new functionality this is a free update to existing licensed users. The installation can be downloaded from the My Products page or from the Trial Downloads page.

Among the major new features are:

  • Support for 32 & 64 Bit applications with the same assembly
  • Support for the latest TWAIN Version 2.1 specification
  • New task oriented online help
  • Visual Studio 2010 Help format included
  • .Net 2.0 and 4.0 assemblies
  • New properties to select the version of TWAIN used
  • TwainAvailable property to confirm TWAIN data source manager is installed

64 Bit TWAIN Issues
We’ve had lots of folks asking about TWAIN support for their 64 applications and this release adds that support. However due to the architecture of the TWAIN support for 64 applications it will only support 64 bit TWAIN drivers. As of now there are not many, if any, true TWAIN Version 2.x 64 bit drivers that we are aware of. This means that applications that must support twain should continue to run as 32 bit applications for compatibility with the most installed scanners drivers. This limitation is a part of TWAIN and not specific to the ImageMan.Net Twain toolkit.

Scanner Manufacturers and 64 Bit drivers
So from a practical standpoint until manufacturers start producing 64 bit drivers it’s not practical to have 64 bit scanning applications. Note that some manufacturers are saying they have 64 bit drivers for 64 bit operating systems but in actuality they just have 32 bit TWAIN 1.9 drivers that run on 64 bit operating systems. These are not the same as a true TWAIN Version 2.x 64 bit driver.

V 8.74 of ImageMan ActiveX Suite Released

6. January 2011 06:17

V 8.74 of the ImageMan ActiveX Suite is now available for downloading.  The installation can be downloaded from the My Products page.  Contact support@data-tech.com if you require assistance downloading the updated files.

This is a maintenance release that fixes the following issues:

  • Fixed an issue which could cause a crash when inserting the image control in a VFP 9 SP2 application
  • Fixed a licensing problem introduced in 8.72 which could cause the Trial Dialog to be displayed even when the license file was installed in the \program files\common files\dti\licenses directory
  • Fixed an issue which caused the Twain control to consume large amounts of memory when accessing the Sources collection and the Twain_32.dll wasn’t installed on the system.
  • Enhanced the PNG Import Filter to be more robust when images have incorrect palette sizes in their metadata.

  • AutoDetect automatically sets the proper init string for Hardware flow control for USR modems.
  • Changes were made to the Transmit code to be more robust when data is received when we are sending the page data. In some prior builds we would not properly handle this leading to No Reponse to MPS/EOP or timeout issues.
