Convert PowerPoint to TIFF
TIFF (Tagged Image File Format) is a lossless raster and high-quality image format. Professionals use TIFF for their design, photography, and desktop publishing purposes. For example, if you want to preserve layers and settings in your design or image, you may want to save your work as a TIFF image file.
Aspose.Slides allows you to convert the slides in PowerPoint directly to TIFF.

Using the Save method exposed by the Presentation class, you can quickly convert an entire PowerPoint presentation to TIFF. The resulting TIFF images correspond to the slides' default size.
This Java code shows you how to convert PowerPoint to TIFF:
// Instantiates a Presentation object that represents a presentation file
Presentation pres = new Presentation("presentation.pptx");
try {
// Saves the presentation as TIFF
pres.save("tiff-image.tiff", SaveFormat.Tiff);
} finally {
if (pres != null) pres.dispose();
}
Convert PowerPoint to Black-and-White TIFF
In Aspose.Slides 23.10, Aspose.Slides added a new property (BwConversionMode) to the TiffOptions class to allow you to specify the algorithm that is followed when a colored slide or image is converted to a black-and-white TIFF. Note that this setting is applied only when the CompressionType property is set to CCITT4
or CCITT3
.
This Java code shows you how to convert a colored slide or image to black-and-white TIFF:
TiffOptions tiffOptions = new TiffOptions();
tiffOptions.setCompressionType(TiffCompressionTypes.CCITT4);
tiffOptions.setBwConversionMode(BlackWhiteConversionMode.Dithering);
Presentation presentation = new Presentation("sample.pptx");
try {
presentation.save("output.tiff", SaveFormat.Tiff, tiffOptions);
} finally {
if (presentation != null) presentation.dispose();
}
Convert PowerPoint to TIFF with Custom Size
If you require a TIFF image with defined dimensions, you can define your preferred figures through the properties provided under TiffOptions. Using the ImageSize property, for example, you can set a size for the resulting image.
This Java code shows you how to convert PowerPoint to TIFF images with custom size:
// Instantiates a Presentation object that represents a Presentation file
Presentation pres = new Presentation("presentation.pptx");
try {
// Instantiates the TiffOptions class
TiffOptions opts = new TiffOptions();
// Sets the compression type
// Possible values are:
// Default - Specifies the default compression scheme (LZW).
// None - Specifies no compression.
// CCITT3
// CCITT4
// LZW
// RLE
opts.setCompressionType(TiffCompressionTypes.Default);
// Depth – depends on the compression type and cannot be set manually.
// Sets the image DPI
opts.setDpiX(200);
opts.setDpiY(100);
// Sets the Image Size
opts.setImageSize(new java.awt.Dimension(1728, 1078));
INotesCommentsLayoutingOptions options = opts.getNotesCommentsLayouting();
options.setNotesPosition(NotesPositions.BottomFull);
// Saves the presentation to TIFF with specified size
pres.save("tiff-ImageSize.tiff", SaveFormat.Tiff, opts);
} finally {
if (pres != null) pres.dispose();
}
Convert PowerPoint to TIFF with Custom Image Pixel Format
Using the PixelFormat property under the TiffOptions class, you can specify your preferred pixel format for the resulting TIFF image.
This Java code shows you how to convert PowerPoint to TIFF image with custom pixel format:
// Instantiates a Presentation object that represents a Presentation file
Presentation pres = new Presentation("presentation.pptx");
try {
TiffOptions options = new TiffOptions();
options.setPixelFormat(ImagePixelFormat.Format8bppIndexed);
/*
* ImagePixelFormat contains the following values (as stated in the documentation):
* Format1bppIndexed; // 1 bits per pixel, indexed.
* Format4bppIndexed; // 4 bits per pixel, indexed.
* Format8bppIndexed; // 8 bits per pixel, indexed.
* Format24bppRgb; // 24 bits per pixel, RGB.
* Format32bppArgb; // 32 bits per pixel, ARGB.
*/
// Saves the presentation to TIFF with specified image size
pres.save("Tiff-PixelFormat.tiff", SaveFormat.Tiff, options);
} finally {
if (pres != null) pres.dispose();
}
