Examples

Shows how to find the corresponding Aspose load/save format from each media type string.

// The ContentTypeToSaveFormat/ContentTypeToLoadFormat methods only accept official IANA media type names, also known as MIME types. 
// All valid media types are listed here: https://www.iana.org/assignments/media-types/media-types.xhtml.

// Trying to associate a SaveFormat with a partial media type string will not work.
Assert.Throws<ArgumentException>(() => FileFormatUtil.ContentTypeToSaveFormat("jpeg"));

// If Aspose.Words does not have a corresponding save/load format for a content type, an exception will also be thrown.
Assert.Throws<ArgumentException>(() => FileFormatUtil.ContentTypeToSaveFormat("application/zip"));

// Files of the types listed below can be saved, but not loaded using Aspose.Words.
Assert.Throws<ArgumentException>(() => FileFormatUtil.ContentTypeToLoadFormat("image/jpeg"));

Assert.That(FileFormatUtil.ContentTypeToSaveFormat("image/jpeg"), Is.EqualTo(SaveFormat.Jpeg));

// For file types that can be saved and loaded, we can match a media type to both a load format and a save format.
