Problems with SetTextExtractionArea

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

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: http://www.debenu.com/kb/extract-text-from-a-defined-rectangular-area-on-a-page/ Your prob has nothing to do with the test license ;-) Cheers and welcome here, Ingo
	Cheers, 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
