I have a Go app that utilizes signature capture for placing on some docs that get exported to PDF's. The problem is that if I scale the container field down to fit on the documents the signature is so light that it can just barely be seen. Even when viewed on the layout they are very light. Is there anyway to make the stroke bolder at capture time on the Go? If not, does anyone know of a way to possibly manipulate the captured PNG inside of the container (adjust contrast or something similar).

If everyone else's experience is similar I may just send this to FM to look at. Considering that the purpose of capturing the sig would be to place of a form of some type it needs to be much bolder.

It may be possible to use a java image manipulation library with ScriptMaster plug-in, but that can't be done directly on FMGo since it will require a plug-in. There are ways to have FM Server process this for you, which can utilize ScriptMaster plug-in. This will require custom Java/Groovy code, and will probably not be a simple task, but this is the only way I can think of doing what you need done.
