Functionality Questions- Replacing Images in Existing PDF

Aspose.PDF Product Family
1

Greetings! I've downloaded the AsposePDF.dll for .NET 3.5, and am running the WinForms.2008 demo to evaluate whether or not this component fits our needs. First I have a couple questions about the capabilities of the tool.

1. Does the tool support adding CMYK images to PDFs?
2. Does the tool support adding multi-layer vector images to PDFs?

Next, I'm attempting to do a proof of concept using the demo... I added the AsposePDF.dll as a reference in the demo project, and everything seems to run fine, but I'm attempting to test the Replace Image functionality (http://www.aspose.com/documentation/.net-components/aspose.pdf-for-.net/replace-image-in-an-existing-pdf-file.html) on an existing PDF. The Document entity isn't recognized even thought the API states it should be available, so am I doing something wrong?

Thanks,
Michael

Hello Michael,

Thanks for your interest in our products.

Currently Aspose.Pdf for .NET supports the addition of all the image formats present under System.Drawing.Imaging.ImageFormat namespace. But I am afraid currently it does not support the addition of CMYK formats. For the sake of implementation, I have logged this requirement as PDFNEWNET-29492 in our issue tracking system. We will further look into the details of this requirement and will keep you updated on the status of correction.

We already have logged the requirement to support Vector images as PDFNEWNET-4592 in our issue tracking system under New Features list. As soon this feature becomes available, we would be more than happy to update you with the status of correction. Please be patient and spare us little time.
