This sample program, PXD_GRAB_CS, illustrates the use of the Imagenation PXD1000 with
the new programming language C#. It shows you how to grab and display an
image and also how to read and write BMP files. It may provide a good
foundation for your first PXD1000 application. Whether you use our sample
as a starting point or not, you will need the interface file contained in
this package if you want to work in C#.
This is what you need for C# development:
In order to develop a C# application for the PXD1000, you
need to have an interface file that redefines all of the PXD1000 functions and links the new definitions
to the existing PXD1000 DLL. As an example, the grab function named ìGrabî in the PXD1000
Digital Frame Grabber Userís Guide has been renamed to ìPXD_Grabî for C#. The two functions ìGrabî and ìPXD_Grabî do exactly the same things,
and hence, you can still rely on all of the information in the userís guide.
This is what we are giving you in this package:
The interface file containing the following three types of data:
| 1. | The DLL function redefinitions - Redefines all the functions that
are explained in the PXD1000 Digital Frame Grabber Userís Guide and contained in the PXD1000 DLLs. |
2. | Global variable definitions ñ A set of common static variable names used by the PXD1000 API. |
3. | Classes - Some useful class functions for initializing libraries, displaying images, and reading and writing BMP files.
You may want to use these functions as your beginning class library to avoid building one from scratch.
|
A sample C# program that illustrates the following concepts:
| 1. | Library initialization - Proper initialization of the PXD1000 libraries. |
2. | Display - Done by getting a pointer to the acquired image using the
PXD1000 FrameBuffer() function and then creating a bitmap by calling the Bitmap() function. |
3. | Continuous image update - Uses a timer to cause the image window to be continuously updated.
|
This is how you use it:
Download this package into a directory where you want to work.
Unzip it into that same directory. Build the sample and execute it to make sure it works. Then modify it for your
application. If you are building a new C# application, you might want to start with our sample code and
classes. If you already have an application that you are porting, you may just want to use our interface
file.
