This calculator can be used to calculate the width and height of a RAW image created by Bullet Creator from the size of the file in bytes. This can be handy when you have stored an image in RAW format and can't remember the width and height of the image. The dimensions of an image aren't stored in the RAW image format, so you'll have to specify them when you want to use the image.
The auto zoom factor makes the image of the sphere and it's shadow fit exactly in the picture. It depends on the direction of the light and the elevation of the sphere where the shadow will be cast and thus what the auto zoom factor is. The factor can be used in the Coords Calculator or as an indication of a regular zoom factor when you want to create an image with some slack beyond the cast shadow.
If your browser supports layers you can try the Colors Converter with layers.
The color values used in Bullet Creator are in normalized decimal format. The color values used in HTML are in hexadecimal format. To convert between these two formats the Colors Converter can be used.
The Coords Calculator calculates the coordinates of the area in a clickable map when you want just the sphere to function as an area that can be clicked. If you used auto zoom to create the image, use the Auto Zoom Calculator to calculate the zoom factor to use here.
