What are the differences between the compressions used in TIFF files?

The Tagged Image File Format (TIFF) is widely popular, and is particularly used in document imaging. It can support a number of compression types:

• Packbits – Created by Apple, this lossless compression type is used for run-length encoding (RLE). Baseline TIFF readers must support this compression. Use this compression for higher compatibility with various applications.
• CCITT (Huffman encoding) – Used particularly for encoding bitonal (or bi-level) images. “Group 3” and “Group 4” are particularly known for its use with fax transmission of images. Using this compression type will help keep smaller file sizes.
• LZW – A lossless compression type that supports multiple bit depths. Because it’s lossless, it produces files that are generally larger than other compressions. Use this compression if you want to retain the exact visual quality of the image without data loss or artifacts.
• JPEG – Very popular compression, used for color and grayscale images and can produce high compression ratios. JPEG allows a good amount of control over how the image in question should be compressed. Use this compression for general color or grayscale images.
• Deflate – A lossless compression using Huffman and LZ77 techniques and also supports different bit depths.

What type of license should I be using?

Accusoft supports 3 primary license types: Evaluation, Toolkit, and Runtime licenses.

Evaluation License:

An Evaluation license is available upon download and will allow you to try our products and determine if they will suit your needs. Most downloads include free demo applications that demonstrate the core functionality of our product and will show you how to get up and running integrating Accusoft products with your solution. While the Evaluation license is free to download it does come with some restrictions. These restrictions may come in the form of water marked documents, pop-up dialogue boxes, or a time limit on the Evaluation license itself.

Toolkit License:

Should you decide that an Accusoft product is right for you, the next step should be to purchase one or more of our Toolkit licenses. Accusoft requires each developer using an Accusoft component to have a Toolkit license on their development machine. Once registered, the Toolkit license will unlock all restrictions of the Evaluation license. Please note, the Toolkit license is strictly to be used for development purposes, and when activated, it will be tied the specific development machine that it was registered on. Understandably, the occasion may arise where a Toolkit license needs to be moved from one development machine to another. In such a scenario, please contact sales@accusoft to see if this is feasible. For more information on how to register a Toolkit license on a development machine please see the ‘Toolkit Licensing’ section of your products Help documentation.

Runtime License:

Finally, once you have completed your solution and are ready for deployment, you will need to purchase a Runtime license. Accusoft offers 2 types of Runtime licenses. Most commonly, you will purchase an Automatically Reported Runtime (or Node-Locked) license, which requires a license for every machine your solution will be deployed to. It is very important to note that Runtime licenses are tied to the machine they are activated on and should not be used for development purposes. Doing so will quickly use up your Runtime licenses and cannot be refunded. For more information about how to activate an Automatically Reported Runtime license, please see the ‘Automatically Reported Runtime License’ section of your products Help documentation. In certain circumstances, Accusoft will issue a Manually Reported Runtime licenses that allow you to embed all of the licensing information directly into your application. These licenses are only distributed under certain circumstances and eligibility is determined by Accusoft sales. For more information on how to activate this type of license, please see the ‘Manually Reported Runtime License’ section of your products Help documentation.

When should I apply image cleanup operations on my document images?

There are a number of cleanup operations that you can use to make an image more suitable for a particular application. What you observe visually on the image and how you perceive its impact on your project is the most important. For example, if you’re noticing very many random specks on your image, and you’re planning to use OCR, then you may want to try a depseckle or blob removal operation first. If the content in your image looks a bit slanted, you could try a deskew or rotate operation. In some cases, using a line removal operation on forms that have grid fields could be helpful also. The amount of image cleaning you may need to do can very from project to project. There’s not a one shot cleaning operation that will always work for all images. But, observe the nature of the noise and interference in your images to determine what general parameters appear to provide the best results.

Why am I unable to obtain a license using the License Manager?

One possibility is that you have strict firewall settings that are preventing our License Manager from connecting with licensing.accusoft.com, our licensing server. In order to connect with licensing.accusoft.com, you’ll have to make an exception in your firewall for our License Manager so that it can connect to licensing.accusoft.com on port 80 for http and port 443 for https.

Why did my license stop working?

There are a couple reasons why a license might stop working. The most common would be if the MAC addresses changed (on a virtual machine, or after significant hardware change). Additionally, a temporary two week license can be put on a machine via the Server Licensing Utility if there are no licenses available when you license a machine. Feel free to contact us at marketing@accusoft.com if you have additional questions. If you want a new license please contact info@accusoft.com.

Why do I get a “80040154 Class Not Registered” error when using the License Development Kit on IIS?

If you are receiving a “80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).” error while trying to use the LDK on a website created through IIS, it is likely because of a platform conflict (x32 vs x64). To fix it, try checking (or unchecking) “Enable 32-Bit Applications” for the App Pool associated with the website.

Why do I still get the “Accusoft Licensing” popup after I have licensed my machine?

There are a few reasons why this might happen:

1. You have licensed your machine with a runtime/deployment license and you are not calling the SetSolutionName and SetSolutionKey methods in your code. By default, Accusoft products will look for a license in the registry at this path: HKEY_LOCAL_MACHINE\SOFTWARE\Accusoft\Licensing\Accusoft. However, for runtime licenses, they are stored at HKEY_LOCAL_MACHINE\SOFTWARE\Accusoft\Licensing\YourSolutionName. So, when you call SetSolutionName, that tells your application to look in the correct directory to find the runtime license. You can find the necessary parameters for these methods on the customer portal customer portal.
2.  You did not successfully install a license on your machine and the temporary license installed has expired. If you use the SLU (Server License Utility) or the LDK (License Deployment Kit) to license your machine and it fails, a temporary 14 day license will be placed on your machine. When that expires, you’ll no longer be able to use the product. If this happens, you’ll need to run the SLU or try using the LDK again. If that doesn’t work, you might want to try licensing your machine in offline mode.
3.  You are trying to use a development license and you are calling SetSolutionName and SetSolutionKey in your code. You should only call SetSolutionName and SetSolutionKey in your code when you are deploying your application and using a deployment license. When you install a development license on your machine, it is placed into the registry at the following path: “HKEY_LOCAL_MACHINE\SOFTWARE\Accusoft\Licensing\Accusoft”. When you call SetSolutionName in your code, you are telling the control to look for a license at a different path: HKEY_LOCAL_MACHINE\SOFTWARE\Accusoft\Licensing\YourSolutionName. If you are calling SetSolutionName and SetSolutionKey while trying to use a developmentlicense, simply comment out those lines for now.
4. The license information you’ve entered might be wrong. Check on the customer portal to make sure you’ve got the values parameters for the SetSolutionKey and SetSolutionNamecorrect.

Why, when I tried to run the SLU, do I get a ” Component ‘COMDLG32.OCX’ or one of its dependences not correctly registered” error?

This error happens if a particular deployment machine doesn’t have the COMDLG32.OCX file registered. To fix this: 1.   Install the comdlg.ocx dependency, if not available on the target machine. If the comdlg.ocx is not present on the system than it will need to be obtained from a system that has it (it should be available on your development machine in the directory mentioned in step 2). 2.   Place the file in the C:\Windows\System32 folder. (C:\Windows\SysWOW64 on a 64 bit machine) 3.   Register the DLL via the regsvr32.exe command. 4.   You should see a successful message and then be able to proceed with the licensing installation.
