How to Generate pdf using Asp.net web api

Question

Hussam Barouqa · Answer

Depending on what source you are using to generate the PDF there is more than one way to do this. Consider using a professional toolkit like LEADTOOLS (https://www.leadtools.com/sdk/document/document-converter) which a number of classes and features that you can implement using server side ASP.NET. For example if your source is an image format and you want to save image PDF you can use the following .NET code in a service: RasterCodecs codecs = new RasterCodecs(); codecs.convert( input file  output.pdf  RasterImageFormat.RasPdfJpeg411 0 0 0 null ); If the source is a document such as Word or HTML you can use the LEADTOOLS Document Converter to produce document PDF. The following code shows how the JavaScript Document Converter Control does that: var url = link to input file ; lt.Documents.DocumentFactory.loadFromUri(url null ) .done( function (document) { var jobData = new lt.Documents.DocumentConverterJobData(); jobData.documentFormat = lt.Documents.Writers.DocumentFormat.user; jobData.rasterImageFormat = lt.Documents.RasterImageFormat.rasPdfJpeg; document.convert(jobData) .done( function (result) { var resultDocument = result.document != null ? result.document.url : result.archive.url; window.open(resultDocument); }) .fail( function (jqXHR statusText errorThrown) { alert( Error converting document  + errorThrown); }); }) .fail( function (jqXHR statusText errorThrown) { alert( Error loading document  + errorThrown); });
