Technical FAQs

Why does my font look different when rendered in PrizmDoc Editor?

If the font in the document is not a font loaded on the server running PrizmDoc Editor, then Editor will attempt to substitute a font that is closest in appearance to the font used in the document.

Does viewing HTML in PrizmDoc Viewer allow JavaScript execution or local file access? Can PrizmDoc Viewer block externally-referenced content from being rendered?

When viewing HTML in PrizmDoc, JavaScript and local file access are disabled.

Additionally, you may configure the security.htmlRendering.blockExternalContent setting found in PrizmDoc’s Central Configuration file. When rendering any source document which uses HTML content, this setting controls whether or not externally-referenced content, such as images and iframes, will be blocked. This option affects any source document file type which uses HTML, including HTML, EML, and MSG.

I’m receiving Uncaught ReferenceError: viewLabel is not defined when trying to embed the PrizmDoc Viewer in my web application. What could be the issue?

This error indicates that the language property in the viewer initialization has not been specified or is undefined.

To fix this, ensure you are loading viewerCustomizations.js.

If the version you are working with predates viewerCustomizations.js, you can get a copy of viewerCustomizations.js from the viewer assets hosted here and update your viewer initialization code.

I’m receiving the error “Uncaught TypeError: Cannot read property ‘viewer’ of undefined” when trying to embed the PrizmDoc Viewer in my web application. What could be the issue?

This indicates that the template property in the viewer initialization has not been specified or is undefined.

To fix this, ensure you are loading viewerCustomizations.js.

If the version you are working with predates viewerCustomizations.js, you can get a copy of viewerCustomizations.js from the viewer assets, hosted here, and update your viewer initialization code.

On Windows, are there any restrictions on the type of account that I can install PrizmDoc under? If so, what are they?

The account that you install PrizmDoc under has to be part of the Local Administrators group. As the installer creates Windows services, administrative-level permissions are required.

What quality should my images be for processing form data and recognition using FormSuite?

In all cases, you want to have your images as clear and as clean as possible. For any particular procedure, please consider the following:

OCR and ICR: Capture images in at least 300 DPI resolution. Ideally, working in black and white allows the objects of interest on your image to be better defined and recognized. Free the image form all noise as much as possible. As if a human were reading it, you want the text objects on the image to be as legible as possible. For ICR, ensure that the characters are printed (no cursive text, etc).

Barcode recognition: As with OCR and ICR, capture images in at least 300 DPI and working with black and white content can provide excellent results. Ensure that the bars in the barcodes are clearly defined on the image and are not malformed (for example, the barcodes should have the proper start and stop sequence, etc). Clear as much noise from the image as possible.

Forms matching and registration: As with the prior 2 items above, capture your documents in at least 300 DPI. Ensure that your resolution is consistent between your form templates and incoming batch images. Form templates should only contain data that is common to every image that is being processed (i.e. Form fields, the text that appears on the blank form itself, etc). The template should not have filled-in field information as this will affect the forms matching process.

How can I improve the performance and memory usage of scanning/recognition in Barcode Xpress?

Barcode Xpress supports a number of optimization settings that can improve your recognition performance, sometimes up to 40%, along with memory usage. The best way to optimize Barcode Xpress is to fine-tune the properties of the Reader class to be specific to your application’s requirements.

BarcodeTypes

• The best way to increase performance is to limit which barcodes Barcode Xpress should search for. By default, BarcodeTypes is set to UnknownBarcode which targets all 1D barcodes.

MaximumBarcodes

• This property will instruct Barcode Xpress to halt searching after finding a specified number of barcodes. The default value is 100.

Area & Orientation

• If you know the location or orientation of your barcodes in your image, specifying an orientation (such as Horizontal) and area can prevent Barcode Xpress from searching for vertical or diagonal barcodes, or in places where barcodes would not exist.

ScanDistance

• Raising this value increases performance by applying looser recognition techniques by skipping rows of an image. However, this may fail to detect barcodes.

Finally, BarcodeXpress Professional edition does not impose a 40 page-per-minute limit on processing.

How do I change the classifier to read a specific language in SmartZone v2

Please refer to the specific code samples below:

1) If you are using the .NET control you set the Language property. For example:

SmartZone2.Reader.CharacterSet.Language = Language.WesternEuropean;

2) If you are using the ActiveX control you set the CharacterSetLanguage property. For example:

SmartZone1.CharacterSetLanguage = SZ_WesternEuropeanLanguages

How do I change between machine print and hand print recognition in the SmartZone v2 SDK?

SmartZone2.Reader.Classifier = Classifier.MachinePrint;
 
SmartZone2.Reader.Classifier = Classifier.HandPrint;
 

SmartZone1.Classifier = SZ_ClassifierMachinePrint

SmartZone1.Classifier = SZ_ClassifierHandPrint

Can I run PrizmDoc Viewer in a Windows Docker container?

No, you cannot run PrizmDoc Viewer in a Windows Docker container. This is because Windows Docker containers do not provide the full environment that a Virtual Machine or regular Windows system install provides.

However, this is not the same thing as using a Windows system as a Docker Host, which actually can run PrizmDoc Viewer in a Linux Docker container.

When running setup.sh and entering the information for a node-locked license, such as configuration file, solution name, and solution key, the following error occurs:

The licensing configuration file you provided is invalid. Please retry
your request or break the licensing process:

What would cause this issue?

This issue may be caused by a trailing space on the configuration file copied to the Linux server.

To remove the space, run the following command, making sure to replace
configurationfilename with the name of your configuration file.

truncate -s -1 **configurationfilename**

For example:

truncate -s -1 /usr/share/prizm/licenseconfiguration.txt

Can I assign a name to each end-user using the Editor for the purpose of track changes?

Yes. When creating an instance of the Editor in your web application, you can configure what the end user’s name and initials should be for track changes. Additionally, you have the option to allow the end user to edit their name and initials. PrizmDoc Editor itself has no user account system; that’s the responsibility of your application. However, when you create an editing session, you can easily configure PrizmDoc Editor to use the username and initials which your application requires. Refer to the PrizmDoc Editor API documentation for more information.
