Добрый день. кто знаком с данными библиотеками? подскажите как добраться до их функций.. очень надо, перерыл все, нашел только на с++, но в нем непонимаю ничего. Если есть у кого ссылка или что то на пример использования функций конкретно этих библиотек. Заранее благодарен.

Скажи откуда стырил возможно и вспомним что. А так заголовочные файлы от них переводи на delphi.

это Futronic сканер отпечатка пальцев, управляющие библиотеки.

> нашел только на с++, но в нем непонимаю ничего


Кидай сюда заголовочный файл и сишный пример использования, если имеется.
Посмотрим что там к чему, вряд ли это хоз-во сложно портировать в Делфи.

Interactive application example

// Application requires interaction with a user.
if( FTRInitialize() != FTR_RETCODE_OK )
return;

// Use the specified sensor.
if( FTRSetParam( FTR_PARAM_CB_FRAME_SOURCE, FSD_FUTRONIC_USB ) == FTR_RETCODE_OK ){

// Get the frame dimensions.
FTRGetParam( FTR_PARAM_IMAGE_WIDTH, &dwWidth );
FTRGetParam( FTR_PARAM_IMAGE_HEIGHT, &dwHeight );
FTRGetParam( FTR_PARAM_IMAGE_SIZE, &dwSize );

pImage = malloc( dwSize ); // Reserve memory space for an image.

// Optional. Set the maximum number of frames in a template. This call must precede
// the FTRGetParam(FTR_PARAM_MAX_TEMPLATE_SIZE, … ) call.
FTRSetParam( FTR_PARAM_MAX_MODELS, 3 );

// Get the maximum template size in bytes.
FTRGetParam( FTR_PARAM_MAX_TEMPLATE_SIZE, &dwTempSize );
FTR_DATA Template;
Template.pData = malloc( dwTempSize ); // Reserve memory for a template.

// Establish the user interaction callback function.
// Note, that the cbUserSuppliedFunc must be declared accordingly to the FTR_CB_STATE_CONTROL,
// see details in the FTRAPI.h header file.
FTRSetParam( FTR_PARAM_CB_CONTROL, cbUserSuppliedFunc );

// Build a template for the verification purpose.
FTR_USER_CTX myContext;
FTREnroll( myContext, FTR_PURPOSE_ENROLL, &Template );

// Verify if a user matches the specified template with the FAR = 0.05
BOOL bIsVerified;
FTRSetParam( FTR_PARAM_MAX_FAR_REQUESTED, 107374182 ); // 107374182 / (2**31 - 1) = 0.05
if( FTRVerify( myContext, &Template, &bIsVerified, NULL ) == FTR_RETCODE_OK ){
if( bIsVerified ){
// Proceed a match!
}
else{
// Match was not detected.
}
}
}

FTRTerminate();

это кусок h-ки  если полностью кидать он здоровый...

Этим попробуй :
http://www.astonshell.ru/freeware/c2pas32/

Заголовки переводит на 3+.

> FTRHANDLE FTR_API ftrScanOpenDeviceOnInterface( int nInterface
> );

const
 ftrScanAPI = 'ftrScanAPI.dll';

function ftrScanOpenDeviceOnInterface(nInterface: integer): FTRHANDLE; stdcall; external ftrScanAPI;

stdcall - это в случае, если там что-то типа #define FTR_API stdcall

по аналогии все остальное переводишь
