Save to Tiff with JPEG compression

Hi,
I have a tiff image that I wish to save as a tiff with JPEG compression.
I don’t see that option under the TiffExpectedFormat enum and the options.

my code looks like this:

using (var image = Aspose.Imaging.Image.Load(memoryStreamIn))

{
    ImageOptionsBase options = new TiffOptions(TiffExpectedFormat.@@what should I choose here??@@);

image.Save(memoryStreamOut, options);
}
is the Tiff with JPEG compression supported?
my Tiff is a scanned grayscale image of a doc. If JPEG is not supported, what would be the best choice for compression?

Hi Oren,

Thank you for your inquiry.

Please note that you may set compression mode by using the Compression property of the TiffOptions class. Your code will look like as follows:

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(@"C:\temp\testimaging.tiff"))
{
Aspose.Imaging.ImageOptions.TiffOptions saveOptions =
new Aspose.Imaging.ImageOptions.TiffOptions(Aspose.Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.TiffJpegRGB);

//Set Compression mode
saveOptions.Compression = Aspose.Imaging.FileFormats.Tiff.Enums.TiffCompressions.Lzw;
image.Save(@"C:\temp\output.tiff", saveOptions);
}

Hi Ikram,
I am trying this on a given tiff. I want to convert it from tiff+Old Jpeg Compression to tiff+new Jpeg Compression.
In one case, the source size was 15kb.
The destination comes out without any compression, so it’s size was 114kb.


when I right click on the image and look at the properties I see that the source is compressed with JPEG, and the dest has no compression.

LZW or any other non-destructive compression doesn’t work well in this case. I need the dest to be compressed with JPEG or similar compression.

here is my code:

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(@“C:\temp\testimaging.tiff”))
{
Aspose.Imaging.ImageOptions.TiffOptions saveOptions =
new Aspose.Imaging.ImageOptions.TiffOptions(Aspose.Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.TiffJpegRGB);

//Set Compression mode
saveOptions.Compression = Aspose.Imaging.FileFormats.Tiff.Enums.TiffCompressions.Jpeg;
image.Save(@“C:\temp\output.tiff”, saveOptions);
}

Attached are the source and output files.
