The details depend on the programming interface (C DLL, C++ class library, .Net classes, etc.) that you use.

For example, if you are using LEADTOOLS .Net programming interface, you can do this as follows:
1. Load the JPEG2000 image to a RasterImage object by using the RasterCodecs.Load() method.
2. If the resolution of the JPEG2000 image is not 600 DPI, you need to change the RasterImage.XResolution and RasterImage.YResolution properties to 600.
3. Save the image to raster PDF format by using the RasterCodecs.Save() method.

You do not need to draw the image on PDF. You only need to call 2 functions:
RasterCodecs.Load(source JPEG 2000 file)
RasterCodecs.Save(target PDF file name)

The Save() function will automatically create a PDF file and save the bitmap as a full page in that PDF. The size of the PDF page will be equal to the size of the loaded bitmap (in inches).

Thanks,
