Technical FAQs

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.

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.

Where can I find code samples for PrizmDoc Editor?

Code samples are embedded in the PrizmDoc Editor API documentation.

What server operating system do I need to run PrizmDoc Editor?

PrizmDoc Editor is delivered as docker image. You can run it on any docker host.

What happens if my Editor client loses connection to the Editor server or my license becomes invalid?

The client currently pings the server every 15 seconds. If it fails to connect or if the license expires and becomes invalid, it will display a dialog indicating that it cannot save changes. The dialog will be dismissed automatically as soon as the connection is restored (or the license becomes valid).

What file formats does PrizmDoc Editor accept?

PrizmDoc Editor currently only accepts .docx files.

Is there a guide for server sizing for PrizmDoc Editor?

With PrizmDoc Editor, most of the processing is done in the client browser. This makes the server hardware requirements quite modest. Due to this operation, there is no need for a complex server sizing guide. Just use any server which meets our minimum hardware requirements (3.75 GiB memory, 1 vCPU, 4 GB SSD storage; in AWS, an m3.medium).

Is it possible to use PrizmDoc Editor to edit a document offline?

No. PrizmDoc Editor is tolerant of network connectivity problems like bad WiFi. However, if PrizmDoc Editor loses connectivity with the server for too long, editing functionality will be disabled until the network connectivity can be reestablished.

How can I improve font fidelity?

We are working on providing you a way to provide us with your own licensed fonts to be used. Watch for this feature in an upcoming release.

Can users download the document they are editing as a PDF?

Not yet, but soon. We’re working on an option which will let you connect your PrizmDoc Editor server to the powerful conversion services available in our separate PrizmDoc Viewer product, which is available as part of our fully-managed PrizmDoc Cloud or self-hosted offering. In this scenario, there will be a Download as PDF option in PrizmDoc Editor.

Can users download the document they are editing as a DOCX?

Yes. By default, the editor menu has a download option that lets the user download the current state of the document as a DOCX file.

Can I prevent users from downloading the document they are editing?

Yes. You can easily remove the download option from the editor menu. Additionally, to completely prevent someone from being able to manually download the document via a network request, you should configure your proxy or web tier to prevent access to the REST API route that supports the download option (GET /api/v1/sessions/:sessionId/document). Refer to the PrizmDoc Editor API documentation for more information.
