What tool is used to generate thumbs? Is that ImageMagick? We are loosing text on the thumbnails and my guess is that we have to configure the fonts. Am I right and how can I configure those fonts?

Thanks in advance,

Peter

You could have different thumbnail definitions and then ask for the one that has the right height and width, but I know what you really want is to be able to specify and arbitrary height and width at thumbnail request time. There’s not a way to do that out-of-the-box that I know of.

<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetObject" ref="thumbnailRegistry"/>
<property name="targetMethod" value="addThumbnailDefinition"/>
<property name="arguments">
<list>
<bean class="org.alfresco.repo.thumbnail.ThumbnailDefinition">
<property name="name" value="scImageThumbnail"/>
<property name="mimetype" value="image/png"/>
<property name="transformationOptions">
<bean class="org.alfresco.repo.content.transform.magick.ImageTransformationOptions">
<property name="resizeOptions">
<bean class="org.alfresco.repo.content.transform.magick.ImageResizeOptions">
<property name="height" value="100"/>
<property name="maintainAspectRatio" value="true"/>
<property name="resizeToThumbnail" value="true"/>
</bean>
</property>
</bean>
</property>
<property name="placeHolderResourcePath"
value="alfresco/extension/thumbnail/thumbnail_placeholder_scImageThumbnail.png"/>
</bean>

</property>
</bean>

> The out-of-the-box thumbnails are registered in the thumbnail-service-context.xml file. I don’t see a clean way to extend that without repeating the definitions, so in my example, I wrote a bean that calls the Thumbnail Registry and registers the custom thumbnail definitions provided in the Spring context file:

Instead of creating a custom bean to register your custom thumbnail definitions, you could have just used MethodInvokingFactory bean to register them directly to the default thumbnailRegistry bean. It is for calling methods on other beans. See the following spring configuration.

It should work, I used this approach in a lot of places while extending Alfresco since spring configurations are not authored extensibility in mind.

That will pull up the placeholder graphic, but no thumb gets generated for that file. Looks like your asset is a graphic, so I’m not sure whether the issue is that they don’t have ImageMagick installed/configured properly or there was some problem creating the rendition for your particular file, or some other issue.

Is it possible to use thumbnails with public alfresco repository?

If I go to “http://cmis.alfresco.com/s/api/node/workspace/SpacesStore/f9bb33bb-652e-432f-bb61-8fbd495cfb06/content/thumbnails/doclib?qc=queue&ph=true” the place holder is created but no thmubnail is created.
