Example: The following example shows how to compose a mutlipage TIFF from individual raster images.
com.aspose.imaging.imageoptions.TiffOptions createTiffOptions
= new com.aspose.imaging.imageoptions.TiffOptions(com.aspose.imaging.fileformats.tiff.enums.TiffExpectedFormat.Default);
createTiffOptions.setSource(new com.aspose.imaging.sources.FileCreateSource("c:\\temp\\multipage.tif", false));
createTiffOptions.setPhotometric(com.aspose.imaging.fileformats.tiff.enums.TiffPhotometrics.Rgb);
createTiffOptions.setBitsPerSample(new int[]{8, 8, 8});
com.aspose.imaging.fileformats.tiff.TiffImage tiffImage = (com.aspose.imaging.fileformats.tiff.TiffImage) com.aspose.imaging.Image.create(createTiffOptions, 100, 100);
try {
// This is Font and Brush for drawing text on individual frames.
com.aspose.imaging.Font font = new com.aspose.imaging.Font("Arial", 64);
com.aspose.imaging.brushes.SolidBrush brush = new com.aspose.imaging.brushes.SolidBrush(com.aspose.imaging.Color.getWhite());
// Create 5 frames
for (int i = 1; i <= 5; i++) {
com.aspose.imaging.imageoptions.PngOptions createPngOptions = new com.aspose.imaging.imageoptions.PngOptions();
createPngOptions.setSource(new com.aspose.imaging.sources.StreamSource(new java.io.ByteArrayInputStream(new byte[0])));
// Create a PNG image and draw the number of page on it.
com.aspose.imaging.fileformats.png.PngImage pngImage = (com.aspose.imaging.fileformats.png.PngImage) com.aspose.imaging.Image.create(createPngOptions, 100, 100);
com.aspose.imaging.Graphics gr = new com.aspose.imaging.Graphics(pngImage);
gr.drawString(Integer.toString(i), font, brush, 10, 10);
// Create a frame based on the PNG image.
com.aspose.imaging.fileformats.tiff.TiffFrame frame = new com.aspose.imaging.fileformats.tiff.TiffFrame(pngImage);
// Add the frame to the TIFF image.
tiffImage.addFrame(frame);
}
// The image was created with a single default frame. Let's remove it.
com.aspose.imaging.fileformats.tiff.TiffFrame activeFrame = tiffImage.getActiveFrame();
tiffImage.setActiveFrame(tiffImage.getFrames()[1]);
tiffImage.removeFrame(0);
// Don't forget to dispose the frame if you won't add it to some other TiffImage
activeFrame.dispose();
tiffImage.save();
} finally {
tiffImage.dispose();
}
