Can not save a tiff file with JPEG compression

[martimanrique]

Hello,

I have tried to save an grayscale 8-bit image to a TIFF file using JPEG compression but the result file is in color and has 24-bit with no compression. This is my code in the ImageAcquired event:

_device.AcquiredImages.TiffCompression = TiffCompression.JPEG
_device.AcquiredImages.TiffMultiPage = true;
_device.AcquiredImages.Last.Save(@"c:\test.tiff");

Can anyone help me please?

Regards.
Martí.

Hello Marti,

Your code is correct.

Current version of SDK creates TIFF files with JPEG compression in RGB color space. We will add ability to create TIFF files with JPEG compression in Grayscale color space in 1 week.

Best regards, Alexander
