[Elphel-support] get image and histogram for the command line

[Sebastien COUDERT]

Bonjour,

thank you very much for the camera configuration from the command line:
curl 
http://192.168.0.9/camvc.php?set=0/comp_run:stop/ae:off/iq:100/e:90/bh:1/bv:1/dh:1/dv:1/comp_run:run

I have two other questions.
I am getting the image from the command line using wget:
wget http://192.168.0.9:8081/bimg

As I have a grayscale CMOS camera, I was looking for a grayscale image;
But, I get a color image (besides, a few pixel are red or green ... 
might be due to JPEG compression).

1. Is it possible to get directly a gray scale image (to get both a 
smaller file size and a closer image to reality) ?
Moreover, how to get the raw image (i.e. not compressed in JPEG format) ?

2. As I understood that histogram was by the FPGA, could I get both the 
histogram and the corresponding image using the command line ? Beware 
that my images are totally different from one shot to an other even at 
10 Hframe per second.

Many thanks in advance.

Cordialement, Sebastien COUDERT.
