HtmlImage (Windward Reports 20.3 API)

java.lang.Object
- net.windward.format.htm.HtmlImage

```
public class HtmlImage
extends java.lang.Object
```
This class contains the information for a single image that will be in a .html file. It is composed of a filename for the tag and a stream to write out the bitmap file.
If the filename is set before the report is processed, that name is read from this object and used in the report. If the name is not set, then the processor will create the name and set it in this object and then use that name in the report. The created names are file1.jpg/png, file2.jpg/png, ...
If a stream is assigned, the image is written to that stream. If the no parameter constructor is used, then a ByteArrayOutputStream object will be created for the stream and the image will be written to that stream. In this case, the stream is guaranteed to be a ByteArrayOutputStream or subclass of ByteArrayOutputStream.
Note: There is no way to set the output stream but not set the file name.
Note: If the filename is set, it's extension is not checked against the filetype and can be anything.

    Create an object with no name and a ByteArrayOutputStream stream.
  - HtmlImage
```
public HtmlImage(java.lang.String fileName,

```
    Create an object with the passed in name and stream.
    
    Parameters:
    
    fileName - The name for this file. If set to "" or null, then the processor will create a filename for this image.
    
    fileStream - The stream to write this image to. If null, the image will not be written to the stream.
  - HtmlImage
```
public HtmlImage(java.lang.String fileName)
