Stored procedures
Lists the values supported by the device camera for a given parameter.
Notes:
  • To modify or find out the current value of a parameter for the device camera, use CameraParameter.
  • CameraListParameter can be used in the Android emulator but not in the simulator.
  • This function is equivalent to VideoListParameter.
Example
// Use the maximum resolution to take a photo
sListResolution is string
sListResolution = CameraListParameter(vipPhotoResolution)
IF ErrorOccurred = False THEN
CameraParameter(vipPhotoResolution, ExtractString(sListResolution, lastRank, CR))
ELSE
Error("An error occurred while retrieving the resolutions supported by camera.")
END
Syntax
<Result> = CameraListParameter(<Parameter>)
<Result>: Character string
  • List of values supported by the camera for the specified <Parameter>. This list has the following format:
    <Value 1>+ CR + <Value 2> + CR + ... + <Value N>
  • Empty string ("") if the parameter is not supported by the camera or if an error occurred while retrieving the parameters.
    The ErrorOccurred variable is set to True if an error occurred. To find out the error details, use ErrorInfo.
<Parameter>: Character String constant or character string
Parameter for which the supported values must be retrieved. This parameter can correspond to:
  • one of the preset constants. These constants correspond to the most common parameters.
  • a character string (between quotes) corresponding to the name of requested parameter.
    Caution: the parameter name is sensitive to the case and to the accented characters. See the documentation about the Android SDK or about the device to find out the name of additional supported parameters. If the specified name does not correspond to a parameter supported by the camera, the function will return an empty string.

vipPhotoResolutionResolutions supported by the camera for taking photos.
The list is sorted in ascending order, from the lowest resolution to the highest one.
The returned values have the following format:
<Width><TAB><Height>
Example:
640<TAB>480<CR>1024<TAB>760<CR>2048<TAB>1240
