How do I construct a pixel image from a data mirror?

Hello,

I get an API that puts pixel image data in the following interface. Now I have to implement its body of content.

C#

getImageData(
	int nDimX,		// x-dimension of data field
	int nDimY,		// y-dimension of data field
	double	*dpData,	// image data field

	double	dXStart,	// x-coordinate of center of first pixel
	double	dXEnd,		// x-coordinate of center of last pixel
	double	dYStart,	// y-coordinate of center of first pixel
	double	dYEnd)		// y-coordinate of center of last pixel

I try to cope with it; unfortunately, there are not so much information about the API. Only I know the *dpData is stored line wise. x0x0, x1y0, … x0y1, x1y1. and the data is mirrored at the x axis.

I don't have experience in image process programming. does anyone have sample code or suggested library to use to handle the image? thanks for your help!

Solution 1

it depends on what system for are working on Windows you best use bitmaps and the GDI.

My favourite articel CXImage about working with bitmaps.

To set a pixel you can use the SetPixel after loading it in a DC. Adavanced is directly access the memory of the bitmap.

Hello, KarstenK:

thanks for your reply. do you think my API interface is enough to construct an image? would you please provide me some sample code to operate *dpData?

Btw, I'm using C#. I'm not sure if System.Drawing is good enough to handle the API
