Setting Driver Properties
Pin Select
You can have different setups for the two pins. For example, you could enable the logo on the capture pin but not on the preview pin, and thereby save some CPU time.

In Figure 52, Browse for File opens a standard file select dialog. Logo files must be:
∙In BMP
∙In PNG format (all commonly used PNG formats are accepted)
If you have a graphic in another format, edit it with a drawing or photo edit program such as Windows Paint, and save it as a PNG file. The PNG format is recommended instead of the BMP format because it is both compressed and lossless – so the image file is smaller, but with no sacrifice of quality. Also, if you use a suitable image editor, you can create transparency effects that are not possible with the BMP format.
It is customary for BMP files to have a filename extension .bmp and PNG files to have the extension
.png. However the driver determines the file type by reading the file header.
