Sensoray 711 - Manual (Page 7)

8 Sensoray Model 711 Instruction Manual
Description: This sample application (written in C) is a faster version of Sample 1. The capture
method makes use of 2 image buffers. While an image is acquired into one buffer, the image acquired
into the alternative buffer will be displayed. This continues in succession. On a moderately fast
computer & video card combination (e.g. Pentium 100 - ATI Graphics Pro Turbo) the rate
approaches 30 frames/sec.
SAMPLE 3 (*** Available only in SX11 "ENHANCED" SDK ***).
Description: This sample application (written in C) is similar to SAMPLE 2, but instead of polling
the READY flag, it makes use of interrupts.
SAMPLE 4 (*** Available only in SX11 "ENHANCED" SDK ***).
Description: This sample application (written in C) illustrates image capture into video card's
memory, and display of text and graphics overlays by use of DirectDraw. This is the fastest method
of displaying the captured image, because it does not involve any additional data transfers. In order to
be able to use DirectDraw features:
a) your video card has to be capable of supporting DirectDraw overlay surfaces in YUV format;
b) DirectX v.5 (or later) has to be installed on your computer.
Windows 95 - download the end user version of DirectX from
http://microsoft.com/directx/resources/dx5end.htm.
Windows NT - download Windows NT 4.0 service pack SP3 from
http://backoffice.microsoft.com/downtrial/moreinfo/nt4sp3.asp.
SAMPLE 5 (*** Available only in SX11 "ENHANCED" SDK ***).
Description: This sample application (written in C) illustrates the use of bimodal image capture: one
field of each frame is captured in color & the other field in monochrome. This mode simplifies
processing in some cases, for example, detecting object boundaries using the monochrome field, and
analyzing the color information using the color field. The sample shows how to handle the image
buffer as two separate buffers, and two separate bitmaps (in case the image display is required).
SAMPLE 6 (*** Available only in SX11 "ENHANCED" SDK ***).
Description: This sample application (written in C) illustrates the interface of an imaging application
built with SX11 SDK to Matrox Imaging Library (MIL) v. 4.00. It is based on SAMPLE 2. By
allocating external buffer, SX11 image buffer is mapped to the MIL image buffer, facilitating direct
image acquisition into the MIL image buffer (to avoid data copying). This sample application
requires MIL libraries to be installed on the computer.
SAMPLE VISUAL BASIC APPLICATION.
The source files for the sample application written in Microsoft Visual Basic v.5.0. To modify the
sample application you will have to create a project file, and specify all necessary components
(including an icon and the VB "include" file).
Description: The VB sample application illustrates calling the sx11.dll functions from Visual Basic.
A printed version of SX11.hlp is included in Appendix A.
