To do this you need to draw multiple panels. How many panels you want to divide the fractal picture into is set in the parameters window. (Get it in the "Windows" menu.) To prevent the need for you to babysit the computer while the panels are drawn, you will want to draw the panels as an automatic sequence.

Let's say you want a picture that measures 24 inches high and 30 inches wide. Let's say you want a pixel density of 600 dots per inch. That makes it 14400 pixels high and 18000 pixels wide. We will have to divide it up. JavaQuat requires, that the number of divisions horizontally and vertically be the same. Let's say we decide to make it 24 panels high and therefore 24 panels wide. Here's what we need to do.

1. Draw the fill picture the size of one panel. That would be 600 pixels high and 18000/24 = 750 pixels wide. This is done with the "Height" and "Width" boxes in the parameters window. (Get it in the "Windows" menu.)

   Optionally, you may want to set the H/W Ratio in the "Settings" menu to ensure that we maintain the 24 to 30, that is 4 to 5, ratio while adjusting just what we want in the picture.
   
   

2. Have that picture just right? Okay, make sure the size is 600 high by 750 wide by checking in the parameters window.
   
   
3. In the second row of the parameters window find the box labeled "Panels" Let the value to 24.
   
   
4. Click on the title bar of the drawing window to mave sure it is the active window.
   
   
5. Go to the "Sequence" menu and select "Sequence Setup...". A dialog box will pop up and you'll need to set some things.
   
   
6. As long as JavaQuat has access to your disk to save the pictures, the top item in the dialog box should be set to "save image and continue". Use the "pause for screen capture" otherwise.
   
   
7. If you've chosen "save image and continue" you will need to pick a folder and file prefix for the pathname of the saved panels. On a Macintosh you might enter "/Star/fractal-panels/panel-" In that case the panels would be written as "/Star/fractal-panels/panel-y00-x00", "/Star/fractal-panels/panel-y00-x01", etc.
   
   
8. Leave the "Zoom" selection as is. The number of frames should be 1, so leave that alone too. Click on the "OK" button and the dialog box will go away.
   
   
9. Finally, go to the "Sequence" menu and select "Start". All the panels will be written to your directory.

If you want to stop in the middle of drawing the panels there are a couple of ways to do that. One is to go to the "Pause" item in the "Draw" menu. When you want to pick up where you left off go to "Sequence" menu and pick "Continue".

If JavaQuat needs to be stopped completely you can still pick up where you left off. When starting up again, look in the directory where the panels were saved. Find the last one drawn and read it back into JavaQuat. Now, to avoid drawing that panel again, advance the X Panel or possible Y Panel settings in the parameters window so they indicate the next panel that needs to be drawn. Follow the steps above for the sequence setup and start. You're going again.

Putting the pieces together

You will need a separate program to do this. JQJoiner is one such, and you can get it free where you downloaded javaQuat. It will assemble any GIF format images, whether or not from JavaQuat. Other programs will also do the job, though they may take more effort that you like.
