    double horizontalResolution = tiffImage.getHorizontalResolution();
    double verticalResolution = tiffImage.getVerticalResolution();
    System.out.println("The horizontal resolution, in pixels per inch: " + horizontalResolution);
    System.out.println("The vertical resolution, in pixels per inch: " + verticalResolution);

    if (horizontalResolution != 96.0 || verticalResolution != 96.0) {

getExifData()

public ExifData getExifData()

Gets or sets EXIF data for the active frame.

Returns: ExifData

setExifData(ExifData value)

hasAlpha()

public boolean hasAlpha()

Gets the Has alpha channel.

Value: The Has alpha channel.

Returns: boolean - the Has alpha channel.

Example: The following example loads a TIFF image and prints information about raw data format and alpha channel.

String dir = "c:\\temp\\";

String fileName = dir + "sample.tif";
com.aspose.imaging.Image image = com.aspose.imaging.Image.load(fileName);
try {
    com.aspose.imaging.fileformats.tiff.TiffImage tiffImage = (com.aspose.imaging.fileformats.tiff.TiffImage) image;

    // If the active TIFF frame has alpha channel, then the entire TIFF image is considered to have alpha channel.
    System.out.printf("ImageFile=%s, FileFormat=%s, HasAlpha=%s\r\n", fileName, tiffImage.getRawDataFormat(), tiffImage.hasAlpha());

    int i = 0;
    for (com.aspose.imaging.fileformats.tiff.TiffFrame frame : tiffImage.getFrames()) {
        System.out.printf("Frame=%s, FileFormat=%s, HasAlpha=%s\r\n", ++i, frame.getRawDataFormat(), frame.hasAlpha());
    }
} finally {
    image.dispose();
}

// The output may look like this:
// ImageFile=c:\temp\sample.tif, FileFormat=RgbIndexed1Bpp, used channels: 1, HasAlpha=False

Gets the options based on the original file settings. This can be helpful to keep bit-depth and other parameters of the original image unchanged. For example, if we load a black-white PNG image with 1 bit per pixel and then save it using the DataStreamSupporter.save(String) method, the output PNG image with 8-bit per pixel will be produced. To avoid it and save PNG image with 1-bit per pixel, use this method to get corresponding saving options and pass them to the Image.save(String, ImageOptionsBase) method as the second parameter.

Returns: ImageOptionsBase - The options based on the original file settings.
