Each time a new page is loaded, ProcessElements is called. This function searches for all images on a page and sets their ImageSource attribute:. Accurate positioning and rendering of text elements proved to be trickier than graphics and images. PDF provides a number of ways for defining text encodings and font types. To alleviate text issues, Amyuni PDF components provide the developers with methods to optimize the text content of a page and convert all text to Unicode.

The OptimizeDocument method is used on the server to optimize text content before attempting to render it in a Silverlight control:. When the font used in the source document is not available on the client PC, Silverlight would substitute with a different font which usually gives results that are not satisfactory. Silverlight provides a mechanism for specifying the font used to display a specific element, as long as the font is in OpenType or TrueType format.

The Downloader object can be used in this case to package all the fonts used by the document. The fonts are embedded in the ZIP package as partially embedded fonts that are not usable by the end-user in order to avoid font licensing issues. Some font manufacturers might still limit the use of licensed fonts, in which case it is recommended that the documents do not use any licensed fonts.

In parallel to the image processing described above, the sample viewer loops through all text objects and sets the font source for each object to be one of the fonts in the ZIP package:. The server-side script can easily be expanded in order to render other types of documents. The PDF Converter product is available for download from this page.

Dany Amiouny , Amyuni Tech Inc. Leveraging the power of Silverlight to view PDF documents and forms. Download a day trial version of PDF Suite Developer Pro Introduction Read the latest advertorial from Amyuni here Using Microsoft Silverlight, developers can provide their users with content-rich web applications that are not limited to text and images, and which can now include complex graphics and better interaction with the users.

Requirements Client Side Any web browser running on any operating system with the Silverlight control version 1. I was, however, faced with a number of challenges: Silverlight supports reading only a single XAML file.

There is no mechanism by which one can feed multiple pages separately, nor is there a way to feed all the resources such as images and fonts used by that page. Silverlight provides no neat way of packaging a document the same way that PDF and XPS do, but requires all the bits and pieces of a document to be created separately on the server and downloaded programmatically using the calling application. This precludes the ability to dynamically stream a document from a server to a client, which is a basic requirement of most applications.

Inconsistencies in the Silverlight object model made trial and error the most time-consuming part of building the sample. Examples of inconsistencies: Accessing the width of a canvas object is done using elem. Width , assuming that elem is an object of type Canvas.

Accessing the left position using elem. Left returns an error and should be replaced with elem. With complex objects such as the Path object, it is difficult to figure out how to access a specific attribute. To access the ImageSource , the right syntax is elem. ImageSource ; the ImageBrush element should be skipped altogether, which did not make sense to me. Free PDF converting software and editor.
