I am getting Access violation reading exception with below code
OCROptions ocrOptions;
ocrOptions = kNoOCR;
Parameters* params = new Parameters();
params->blackText = false;
params->cmapDir = “”;// “D:\\test\\PDFAlchemistTest\\PDFAlchemistTest\\Debug\\output2”;
params->disableAcroform = false;
params->enableAcroformReflow = false;
params->enableBookmarks = true;
params->enableCaptions = false;
params->enableInfographicDetection = true;
params->enableLayoutDirectionDetection = true;
params->enableLogging = false;
params->enableXmlOutput = false;
params->fontDirectoryPath = “/images”;
params->fontFilenamePrefix = “”;
params->mergeSpan = false;
params->removeHyphen = false;
params->removeInvisibleText = false;
params->singleFile = false;
params->skipHeaderFooter = false;
params->skipPageBackground = 0;
params->splitByBookmarkDepth = 0;
params->splitByEveryNumberOfPages = 0;
params->tablesOnly = false;
params->useAccurateGlyphBox = true;
params->usePdfEmbeddedFont = true;
params->singleFile = true;
params->graphicsOutputDpi = 200;
params->ocrMode = ocrOptions;
params->imageDirectoryPath = “/images”;
params->imageFilenamePrefix = “”;
params->enableInfographicDetection = true;
params->enableLayoutDirectionDetection = true;
params->linkStyleUnspecified = false;
params->purpose = kBalanced;
const char* outputDir = “D:\\test\\PDFAlchemistTest\\PDFAlchemistTest\\Debug\\output2”;
Result res = processPdf(“D:\\test\\PDFAlchemistTest\\PDFAlchemistTest\\Debug\\Moby_Dick.pdf”, outputDir, params, NULL);
In debug, res has the value -858993460
So it seems there is some issue with the input params. what could be issue?
Is there any example to refer for valid params?

We attempted to reply via email some time ago but have not gotten a response from you.

I am not able to fully answer the question given the code that you provided. Could you instead provide the buildable / runnable sample that demonstrates the problem?

This would be ideal.

We apologize for the inconvenience in getting this solved. If you can provide us with a sample that demonstrates the problem then we can start investigating the issue.

I look forward to your reply.
