Export multiple pages via the JPG filter

[aroxo]

Hey All,

I am using Open Office on a Debian set-up through the Uno API using Unoconv. I'm trying to export all slides from a pptx into JPGs, but the export only outputs a JPG of the first slide, not all slides.

I can do it fine with the HTML export and the PDF export.

Is there a command I can pass through to the filter to control what is exported?

Also there is an error in the export for cropped images in pptxs (but not in ppt), it's no biggie for me, but might be something someone would like to be aware of.

Cheers,

Matt.

From what I can see in the Developer's Guide under Exporting Drawing and Presentation documents, the export method will only handle one Draw Page (one slide) at a time.

The method name setSourceDocument() may be confusing. Actually, the method
would allow exporting entire documents, however, it is only possible to export draw
pages, single shapes or shape collections from a drawing document.

The filter options can affect the format of the export, but I don't see a way to change the limitation on what can be exported.

Hi - thanks for the response. Do you know if there a way to control which page it exports?

In OO Basic it looks like this:

Code: Select all

Dim Props(1) as New com.sun.star.beans.PropertyValue
oSM = GetProcessServiceManager
ExportSrv = oSM.createInstance("com.sun.star.drawing.GraphicExportFilter")

oDPages = ThisComponent.getDrawPages()
oPage = oDPages.getByIndex(3)

ExportSrv.setSourceDocument(oPage)
Props(0).Name = "MediaType"
Props(0).Value = "image/jpeg"
Props(1).Name = "URL"
Props(1).Value = "file:///C:/Exported.jpg"
ExportSrv.filter(Props)
