Disable XLSX Preview on Alfresco Share

marcog — Tue, 31 Jan 2023 15:06:58 GMT

Hello everybody.

I want to disable the visualization of .xlsx type documents in Alfresco Share 7.2. The thumbnail has already been successfully disabled, now what I want is to disable the document preview when I select it.

I don't want you to render it.

What I need is to disable the transform of xlsx files (they are big files) because they are taking more than 5 minutes to render and display in Share Web Preview, and this is leading to processing overhead in Alfresco.

Is there any way in alfresco-global.properties or share-config-custom about this?

Please, can anyone help me?

Marco

Hi, sorry.

Do you have a ideia of:

disable the transformation from Office formats to PDF - then, as a result, web preview will also not be shown

Thanks

For this use case maybe implement a Surf extension module using a sub-component + evaluator to conditionally remove the web-preview component for ignore the web preview only for big xlsx is the better thing todo.

Here the "no-webpreview-for-big-xlsx-extension.xml" code:

<extension>
    <modules>
        <module>
            <!-- https://hub.alfresco.com/t5/ecm-archive/document-preview-on-and-off-on-user-request/m-p/259355 -->
            <id>no-webpreview-for-big-xlsx-extension</id>
            <version>1.0</version>
            <auto-deploy>true</auto-deploy>
            <!-- HERE PUT A EVALUATOR FOR ACTIVATE THIS ONLY FOR XLSX > 10 MB OR SOMETHING LIKE THAT -->
            <evaluator type="default.extensibility.evaluator"/>
            <configurations>              
                 <config evaluator="string-compare" condition="DocumentDetails">
			      <document-details>
			         <!--  display web previewer on document details page, it should be
			         enough but for some reason seem not to work, so i override the sub-component -->
			         <display-web-preview>false</display-web-preview>
			      </document-details>
			   </config>
            </configurations>			
            <components>
				<component>
					<scope>template</scope>
					<region-id>web-preview</region-id>
					<source-id>document-details</source-id>
					<sub-components>
						<sub-component id="default">
							<evaluations>
								<evaluation id="hide">
									<render>false</render>
								</evaluation>
							</evaluations>
						</sub-component>
					</sub-components>
				</component>
			</components>
        </module>
    </modules>
</extension>

Then replace the default evaluator with a customized one.
