L’exemple suivant montre comment convertir une présentation en document TIFF avec une taille d’image personnalisée en utilisant la classe TiffOptions.
string FilePath = @"..\..\..\Sample Files\";
string srcFileName = FilePath + "Conversion.pptx";
string destFileName = FilePath + "Converting to Tiff as defined format.tiff";
//Instantiate a Presentation object that represents a Presentation file
Presentation pres = new Presentation(srcFileName);
//Instantiate the TiffOptions class
Aspose.Slides.Export.TiffOptions opts = new Aspose.Slides.Export.TiffOptions();
//Setting compression type
opts.CompressionType = TiffCompressionTypes.Default;
//Compression Types
//Default - Specifies the default compression scheme (LZW).
//None - Specifies no compression.
//CCITT3
//CCITT4
//LZW
//RLE
//Depth - depends on the compression type and cannot be set manually.
//Resolution unit - is always equal to "2" (dots per inch)
//Setting image DPI
opts.DpiX = 200;
opts.DpiY = 100;
//Set Image Size
opts.ImageSize = new Size(1728, 1078);
//Save the presentation to TIFF with specified image size
pres.Save(destFileName, Aspose.Slides.Export.SaveFormat.Tiff, opts);
