Annotations on 16 bit gray scale image

    Question

  • I am assigned a task 2 days back to take a 16 bit grayscale image in raw  pixel data..create annotations on top of that and again get the new image data in buffer.Can u please guide through steps.

    I decided to use Direct2d for these.So i Initialy started with 8 bit grayscale image.i created a wicbitmap using data then i created a render target on top of that then i draw something and later i read those data back into buffer

    It was working fine.Now i wanted to do it with 16 bit grayscale data..and i created a wicbitmap.so what rendertarget should i choose so it supports 16 bit data..I m am fine even it becomes 48 bit as in 16 bits per channel

  • Thank you for your support

    I would explain my problem more specifically

    I work with Dicom files.dicom files are self contained files contating medicalimages,Images are grayscale image and can be 12 bit or 14 bit image.Now i wanted to draw annotation on top of these.I donot have an option of making it 8 bit becuase while exporting i give option of 12 bit to user.So i cannot downgrade my image to 8 bit.

    I have a 16 bit grayscale in memory.i Wanted to load it on bitmap draw some lines and the pixel data back

  • Hi there,

    So for 48 bit, how about handling R,G B channel separately like the 8 bit dealing way?

    or have you checked this sample: http://code.msdn.microsoft.com/windowsapps/Direct2D-and-WIC-Image-149448cf?

    Regards,

    Jenny
