Hello Yee,
This depends on the content of the object that you want to convert to image.

What is the nature of this object?
Is it a shape? A file?
Does it contain actual image (pixel) data?
Does it contain a different type of data?

In general, if the object contains actual image (pixel) data, and you want to save it as (PNG or JPG) file, you can use LEADTOOLS .NET classes to:
- Create a RasterImage object of your pixel data.
- Save the RasterImage object to any supported image format including PNG and JPG.

The code will be something as follows:
using (RasterCodecs _codecs = new RasterCodecs())
{
RasterImage img = new RasterImage(RasterMemoryFlags.Conventional,
lWidth, //lWidth: Image width
lHeight, //lHeight: Image Height
24,
RasterByteOrder.Bgr,
RasterViewPerspective.TopLeft,
null,
IntPtr.Zero,
0);

if (null != img)
{
//pData: The actual pixel data from your object
//lSize: The size of the pixel data
img.SetUserData(new IntPtr(pData), lSize);
}

_codecs.Save(img, @"d:\res.png", RasterImageFormat.Png, 24);
}
