Griaule Biometrics

hi there,

I am a powerbuilder developer. like you i also tried developing biometric using powerbuilder but the problem is i cannot extract the template after acquiring the rawimage. there is an error when i call function EXTRACT.

Hola trate de usar el SDK Griaule con PowerBuilder la version con DLLs y no se puede... con el activeX lo logre pero se cuelga... en la funcion Identify se cuelga... al parecer por que recibe el template como un arreglo de bytes y en powerBuilder no existe ese tipo de dato, asi que utilice blob... es el unico tipo de dato que me acepta, pero se cuelga power builder...

Alguien tiene idea como usar el SDK con PowerBuilder?

Hi there!

I tried to use Griaule SDK DLL version with Power Builder and I couldn't...
Then I tried to use the activeX version... and it works fine until I reach the method IDENTIFY...
I guess it's because the Identify method recieve a byte array and Power Builder doesn't have such datatype... so I used blob... that's the only datatype that the function recieves...
but Power Builder hang up!!!

Anyone knows how to use the SDK with PowerBuilder correctly?

hi,
I also used activeX using powerbuilder but when i call the EXTRACT
function it return an error (-2). how did you extract the template? did you check the return value of the function EXTRACT? I guess your almost there but you only lack one function to be called before you call the IDENTIFY function. by the way what is the version of powerbuilder you are using? I am using PB 7.0.

Hi there
I'm using power builder 10 and yes. I'm checking the return value. I don't have an error running extract function. I use a variable
blob{10000} template
and set the variable size = 10000
before you call EXTRACT

but there is an error the EXTRACT function don't return anything...
even the array size...

Actually I'm trying the 4.1 ActiveX Free. and 4.2 (actual version)
If you find any way to get results please tell me.

here is my code of calling extract function.

blob{10000} template
long size
int liRet

size = 10000
liRet = grX.Object.extract(rawimage,width,ocx_height, res,template,size,0)
messageBox("",liRet)

grx is the name of the ole object.
i have already called the pre-requesite function like INITIALIZE,CAPSTARTCAPTURE.

buenas noches estoy  nuevo en el area y quisiera saber si se puede mostrar en pantalla la imagen capturada de la huella y como es la linea de comando ....

estoy utilizando powerbuilder 11.5

muchas gracias..

Estimado cliente,

Sí, se puede mostrar la imagen de la huella dactilar en la pantalla.
Si lo desea, puede descargar e instalar el SDK de la huella digital, para que pueda probar nuestras aplicaciones de muestra disponibles en descarga.
Hay un montón de ejemplos que, para ayudarle a empezar con su propio desarrollo. Desafortunadamente no tenemos muestras en PowerBuilder específicamente. También hay un manual, donde puedes encontrar todas las funciones del SDK apoya, y lo que uno hace. El manual puede ser acessed través de este enlace: http://www.griaulebiometrics.com/page/es/manual/fingerprint-sdk/programming-reference-guide

Saludos cordiales,

Dear customer,

Yes, you can display the image of the fingerprint in the screen.
If you want, you can download and install Fingerprint SDK, so you can test our sample applications available at Downloads.
There are a lot of examples there, to help you start with your own development. Unfortunately we do not have samples in PowerBuilder specifically. There's also  a manual, where you can see all the functions the SDK supports, and what which one does. The manual can be acessed through this link: http://www.griaulebiometrics.com/page/es/manual/fingerprint-sdk/programming-reference-guide
