Data Readout Order

ReverseRows and ReverseCols entries in the VuQuest2D.ini file provide information on whether the pixel
read-out order for the image sensor rows and columns respectively should be reversed. The specified
value can be either 0 (FALSE) or 1 (TRUE). By default, both values are set to 0 (FALSE), meaning that
the read-out orders are not reversed.

Image Size

The maximum (which is also a default) image size supported by the IS4910 camera is 1280 x 960 (1280
columns by 960 rows). The number of rows and columns can be changed using the entries ImgHeight
and ImgWidth respectively.
Camera Support Library CamLib

The Camera Support Library CamLib provides a set of convenient APIs, which a user application can call
to easily acquire images, inquire or change the camera parameters. The library comes in two formats –
as a static library camlib.lib and as a DLL camdll.dll. A decision whether to use the static or dynamic
library is made by a user-programmer depending on his/her preferences and tools used to compile and
build user applications. Note that the Metrologic Demo Application is linked statically with CamLib, and
therefore, does not require the CamLib DLL to be installed on the target device. If a user application is
designed to use CamLib DLL, then the CamLib DLL must be installed on the target device. Details on
how to install IS4910 software on the target device are described in the Downloading Software to the
Target Device section of this document.
Omniplanar® Barcode Decoding Library SwiftDecoder®

An optional decoding library SwiftDecoder is available upon request under a license agreement. Please
contact your sales representative at Metrologic Instruments, Inc. (www.metrologic.com), or
Omniplanar, Inc. (www.omniplanar.com) for details.
Metrologic Demo Application

The Metrologic Demo Application is a pre-compiled executable program demonstrating the basic
capabilities of the IS4910 camera. The source code of the Demo Application is also provided in the
IS4910 installation package.
