API documentation mistake #1396

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The documentation says that SetImage does not create a copy of Pix:
https://code.google.com/p/tesseract-ocr/source/browse/api/baseapi.cpp#534
but in implementation it does(twice):
https://code.google.com/p/tesseract-ocr/source/browse/api/baseapi.cpp#926
https://code.google.com/p/tesseract-ocr/source/browse/ccmain/thresholder.cpp#143
Am I right?

Not quite. The documentation says "Tesseract doesn't take a copy or ownership 
or pixDestroy the image", meaning the image data itself, not Pix. pixClone 
returns a new pointer to the same structure, so while there is a copy(/are two 
copies) of the Pix, there's no copying of the image.
