Tesseract OCR uses it. Making a e-signature can use it ? Anything else ? Does it need to be on every Synapse Client ?
add results also uses it ... to convert images to jpeg for previewing and autofile uses it and something else ... My view is that it's easier to install it than have to install it when you need it.
My images seem to load file without it, I guess that is because they are already .jpg I thought so. Good idea.
