how can we crop or resize image? ABBY fine reader will set image size by default to get better quality?
For example my input images can be different sizes. Can Abbyy resize the images so that the accuracy can be increased?

Hi Rama
What have you tried so far? Can you please post your Java-code?
The "PagePreprocessingParams Object" can help you a lot, see the documentation

Hi Koen,
what is the difference between skew and orientation?
Hi Rama
Your "new" question is not actually about resizing but is more likely to be extended in your other question:
https://forum.ocrsdk.com/thread/skew-and-orientation/
Basically, the main difference is
- skew: a page/document that has been scanned al little skew
- orientation(-detection) : landscape vs portrait - or detection of it - and/or automatically rotate
See both image below:
Skew:
Orientation:
OrientationCorrection: (ABBYY FineReader can rotate this page to show it correctly)

Hi
check below code and input output.
private void processImage() {
// String imagePath = SamplesConfig.GetSamplesFolder() + "//home//DCXMprod//ABBYY//Samples//images//Charlotta_1.jpg";
String imagePath = SamplesConfig.GetSamplesFolder() + "images/skew/Doc_2.pdf";
try {
// Don't recognize PDF file with a textual content, just copy it
// Create document
IFRDocument document = engine.CreateFRDocument();
try {
// Add image file to document
displayMessage( "Loading image..." );
document.AddImageFile( imagePath, null, null );
//pages=document.getPages();
IDocumentProcessingParams docProcessingParams =engine.CreateDocumentProcessingParams();
IPageAnalysisParams tabParams=docProcessingParams.getPageProcessingParams().getPageAnalysisParams();
tabParams.setDetectText(true);
tabParams.setEnableTextExtractionMode(true);
//tabParams.setAggressiveTableDetection(true);
//tabParams.DetectTables=true;
//orientation
IPagePreprocessingParams pageproparams=engine.CreatePagePreprocessingParams();
pageproparams.setCorrectOrientation(true);
IXLExportParams xlparam=engine.CreateXLExportParams();
xlparam.setLayoutRetentionMode(XLSXLayoutRetentionModeEnum.XLLRM_ExactLines);
xlparam.setTablesOnly(true);
// Save results
document.Process(docProcessingParams);
//displayMessage( "Saving results..." );
// Save results to pdf using 'balanced' scenario
String texExportPath = SamplesConfig.GetSamplesFolder() + "images/skew/Doc_2ori.txt";
document.Export( texExportPath, FileExportFormatEnum.FEF_TextUnicodeDefaults, null);
String xlExportPath = SamplesConfig.GetSamplesFolder() + "images/skew/Doc_2orie.xls";
document.Export( xlExportPath, FileExportFormatEnum.FEF_XLSX, xlparam);
} finally {
// Close document
document.Close();
}
} catch( Exception ex ) {
displayMessage( ex.getMessage() );
}
}
Hi Rama
Can you please edit both posts and place the Java-code within the block-quote tag?
Thanks.
Also, Your excel-sheet is not readble.

PS. Here one of my examples:
I need to crop images with high quality because I want to upload images on my resume website. I want to gather some data from resume centers before this I need to read resume center reviews to write better resumes. I need to make resumes and upload images on my websites. Please help me to crop images with high quality.
