Gif File Formatting:
To change this setting, press the <F7> key and click on the Html tab. At the top left corner of this tab are two spinedit fields for setting the width of your *.gif images for the birth chart that is currently displayed in screen pixels.
When you have a bi-wheel displayed, the field "Bi-Wheel Width" is the value that is used to set the width of the image in the Image Viewer that can be saved as a gif file or automatically created by clicking the "Html Report" button. Alternatively, the "Uni-Wheel Width" field is for single chart displays such as the uni-wheel and square chart.
