ZWO ASI224MC - can SharpCap save 12-bit data
Posted: Mon Sep 14, 2020 1:48 am
When I use my ASI224MC in Raw16 mode I see a nice debayered image on screen. The color looks good. When I capture a "snapshot" the .png appears monochrome at first glance. I can Debayer the image in PixInsight and see the color. What I am wonder is: does SharpCap capture 12-bit color (the max # of bits you can get from the ASI224MC)?
The reason I am asking is what I read when I look at the ZWO SDK rev 2.8 dated 2018-08-08.
The function ASIGetVideoData(int iCameraID, unsigned char* pBuffer, long lBuffSize, int iWaitms) says this about the buffer size:
I don't have my files in front of me, but the snapshot from SharpCap in RAW16 mode is IIRC size for 2 bytes per pixel.

- bufSize Byte length for RAW8 and Y8 bufSize >= image_width*image_height for RAW16 bufSize >= image_width*image_height *2 for RGB8 bufSiz >= image_width*image_height *3
