I have installed the library with a test license, using Visual Studio for C++ and linking with static library.

If I try DPLGetPageTextA, DPLExtractFilePageTextA or DPLDAExtractPageTextA every thing works fine.

If I try to use DPLSetTextExtractionArea( 0, 0, DPLPageWidth(InstanceID), DPLPageHeight(InstanceID) before of DPLGetPageTextA I get a blank string.

If I try to use DPLDASetTextExtractionArea before DPLExtractFilePageTextA or DPLDAExtractPageTextA I get blank strings too.

Is it possible to be a problem with the test license or something similar?

Code Sample:

DPLLoadFromFileA(InstanceID, (char *)(const char *)FileName, NULL);

DPLSetMeasurementUnits(InstanceID, 1);

DPLSelectPage(InstanceID, 1);

DPLSetOrigin(InstanceID, 0);

// This line is the problem... if I remove it, the text is extracted

DPLSetTextExtractionArea(InstanceID, 0, 0, DPLPageWidth(InstanceID), DPLPageHeight(InstanceID) );

CString txt = DPLGetPageTextA(InstanceID, 8);

Thank you

Hi Antonio,

here's a sample from the official support pages:

Your prob has nothing to do with the test license ;-)

Cheers and welcome here,

Ingo

Hello Ingo

You are right... I have rewritten my code and now it works fine, as described in documentation.

Is was my fault.

Thanks a lot
