`$value`	mixed	Tag value

setExif

Add multiple EXIF tags at once

Raspistill::setExif( array $tags ): $this

]);

Parameters:

Parameter	Type	Description
`$tags`	array	Associative array where key=EXIF tag name & value=tag value

See Also:

\Cvuorinen\Raspicam\Raspistill::addExif

disableExif

Prevent any EXIF information being stored in the file.

Raspistill::disableExif(  ): $this

This reduces the file size slightly.

linkLatest

Link latest picture to filename.

Raspistill::linkLatest( string $filename ): $this

Parameters:

Parameter	Type	Description
`$filename`	string

Take a picture and save with the given filename

Raspistill::takePicture( string $filename )

Example:

// Take picture with default configurations
$camera->takePicture('pic1.jpg');

Parameters:

Parameter	Type	Description
`$filename`	string

startTimelapse

Take pictures with timelapse mode.

Raspistill::startTimelapse( string $filename, integer|float $interval, integer|float $length, string $timeUnit = self::TIMEUNIT_SECOND )

Note you should specify %04d at the point in the filename where you want a frame count number to appear. e.g. 'image%04d.jpg'. Note that the %04d indicates a 4 digit number with leading zero's added to pad to the required number of digits. So, for example, %08d would result in an 8 digit number.

If a timelapse value of 0 is entered, the application will take pictures as fast as possible. Note there is an minimum enforced pause of 30ms between captures to ensure that exposure calculations can be made.

Time unit can be one of: Raspicam::TIMEUNIT_MINUTE, Raspicam::TIMEUNIT_SECOND, Raspicam::TIMEUNIT_MILLISECOND, Raspicam::TIMEUNIT_MICROSECOND.

Example:

// take picture every ten seconds for two minutes
$camera->startTimelapse('image%04d.jpg', 10, 120);

Parameters:

Parameter	Type	Description
`$filename`	string
`$interval`	integer\|float	Time between shots.
`$length`	integer\|float	Time how long to keep taking pictures.
`$timeUnit`	string	Optional. Time unit for $interval and $length. Default: `Raspicam::TIMEUNIT_SECOND`
