hi i'm trying remove white margins around pages on document via acrobat 8.1 sdk , struggling workout how go (basically same functionality if document>crop pages>remove white margins). my code works fine point of cropping, document created via scanner , don't know cropping rectangle be. i'm guessing can found programmatically using media box, have no clue how so. any appreciated! there no "box" in pdf represents white margins. on non-scanned pdf can figured out finding bounds of each actual object , using math. on scan, it's more complex involving interesting pixel logic. you need things , set cropbox via iac. iac doesn't give access objects of page :(.

estoy confuso y no se si se puede hacer mi proyecto. tengo un programa para hacer fotos o videos (fotomaton). estado investigando y visto que con arduino se puede mandar señal del pc al arduino y este hacer lo que tenga programado. pero, ¿como hago para sacar la señal del programa que tengo y mandar la señal al arduino? ¿esto se puede hacer? gracias. mal expuesto tu objetivo: que quieres que haga el arduino? la pc le puede enviar via puerto serie un comando y arduino responderá según su programa (sketch) pero tu no explicas bien y si dices haber investigado no lo hiciste bien tampoco porque enviarle datos por puerto serie via usb es básico en cualquier microcontrolador no solo arduino. hacer que un micro haga lo que quieres es básico también. asi que intenta ser mas descriptivo. incluye algun link si lo tienes de lo que pretendes hacer.

ciao tutti, spero di non aver sbagliato la sezione, sto realizzando un sistema di timming gps da inserire nella mia moto e come mi aspettavo sono davanti un problema matematico. l'hardware utilizzato è un circuito standalone bluetooth che monta un arduino atmega168 + scheda bluetooth. ho utilizzato questo dispositivo perchè è molto piccolo e facile da sistemare nella moto. utilizzando un antenna gps bluetooth già inserita nella mia moto riesco ricavarmi le coordinate gps. grazie alla libreria tinygps(conosciute grazie al vostro forum) riesco tradurre perfettamente dati dal gps. (fino quì tutto ok) leggendo in questo forum e in altri non ho trovato niente che mi è utile, mi spiego meglio ovunque leggo topic che spiegano su come calcolarsi velocità, posizione, relivazione del punto dove si trova il dispositivo, tutto molto bello e interessante ma non è il mio caso. dopo questa premessa arrivo al mio problema: obiettivo: realizzare un sistema di timming dei giri percorsi in

i know couple of networks cards exist - pci card s pc - allows direct fiber optics connectivity, question remains trying replace traditional media converter (fiber optics rj45). , trying in lowest space possible. my initial reaction headline question: "is possible connect 2 rasperry through fiber optic?" - simple, use pair of media convertors. (they don't have handle rj45 [ethernet], can rs232 serial convertors well.) i'm puzzled want replace solution. in principle suppose 'blinking' led , launching light 1 end of fibre, detect , decode @ other? there seem whole lot of basic engineering challenges there media convertor sellers have tackled? fun try though... maybe else can think further outside box can? raspberrypi
