Resizing Image Attachment

atodeschini
I'm creating a form with an image attachment section for a signature. I need to make this automatically resize the image to a set height/width. How do I do that?

Here's what I have (straight from the image attachment add-on)

xmlns:pipeline="java:org.orbeon.oxf.processor.pipeline.PipelineFunctionLibrary"
                                                     class="fr-attachment"
                                                     id="control-11-control"
                                                     bind="control-11-bind">
                                    <xforms:label ref="$form-resources/control-11/label"/>
                                    <xforms:hint ref="$form-resources/control-11/hint"/>
                                    <xforms:help ref="$form-resources/control-11/help"/>
                                    <xforms:alert ref="$fr-resources/detail/labels/alert"/>
                                    <xforms:filename ref="@filename"/>
                                    <xforms:mediatype ref="@mediatype"/>
                                    <xxforms:size ref="@size"/>
                                </fr:image-attachment>
                               
                            </xhtml:td>
                        </xhtml:tr>
                        <xhtml:tr/>
                        <xhtml:tr>
                            <xhtml:td/>
                            <xhtml:td>
                                <xforms:input xmlns:xbl="http://www.w3.org/ns/xbl"
                                              xmlns:fb="http://orbeon.org/oxf/xml/form-builder"
                                             


Thanks in advance!

Andrew,

There is no built-in resizing facility in the XForms engine.

Somehow you would have to hookup resizing code to achieve this. You
could submit the image to a local service doing that, or call Java
code. But it's not built-in.

We have an Image Server processor which contains code that might be reusable:

https://github.com/orbeon/orbeon-forms/blob/master/src/java/org/orbeon/oxf/processor/ImageServer.java
