An example of the URL set with parameters in
(p. 32) is:
http://1.2.3.4/data.json?immediate_resolution=5&immediate_quality=2&immediate_
af=1&immediate_pos=0. Once the parameters are set, use the image capture URL
http://1.2.3.4/capture.jpg (where 1.2.3.4 is the IP address of the camera) to capture the image
using the parameters set.
Download an example CRBasic program illustrating the use of the
HTTPGet
instruction to set
these parameters and initiate an image capture from
www.campbellsci.com/downloads/ccfc-
.
NOTE:
Once the parameters are set, the camera will save the set parameters for use on the next URL
capture while you remain on the CCFC webpage. The parameters return to default after a
rest/power down.
