image to pdf help

[Bryan K Cantwell]

I am trying to allow for as many image types as possible to be allowed 
in my form for addition to a pdf.
Right now I can do jpg and tif, but really also need png and bmp, and 
any other you may know.

Here is the code I have so far that works:
                PDXObjectImage yimage = null;
                if (logo.toLowerCase().endsWith(".jpg")) {
                    yimage = new PDJpeg(doc, new FileInputStream(logo));
                } else if (logo.toLowerCase().endsWith(".tif") || 
logo.toLowerCase().endsWith(".tiff")) {
                    yimage = new PDCcitt(doc, new RandomAccessFile(new 
File(logo), "r"));
                } else {
                    throw new IOException("Image type not supported:" + 
logo);
                }
Any help adding at least bmp and png to this 'if else'?

Thanks,
