5.4.2.6 Picam_SetParameterFloatingPointValue()
Description
Picam_SetParameterFloatingPointValue()
sets a parameter to a specified
floating point value during hardware setup.
Syntax
The syntax for
Picam_SetParameterFloatingPointValue()
is:
PICAM_API Picam_SetParameterFloatingValue(
PicamHandle camera_or_accessory,
PicamParameter parameter,
piflt value);
Input Parameters
Input parameters for
Picam_SetParameterFloatingPointValue()
are:
Output Parameters
There are no output parameters associated with
Picam_SetParameterFloatingPointValue()
.
Advanced API Usage
When used in conjunction with Advanced APIs, if
camera_or_accessory
is a camera
handle, it may be a handle to either the:
•
model
;
The
model
parameter may be set independently from the corresponding
device
parameter. However, doing so requires that all parameters be committed to the
device
prior to starting any data acquisition by calling
Picam_CommitParameters()
.
•
device
.
Setting a
device
parameter automatically sets the corresponding
model
parameter to the same value.
