Hey Paul, I am getting an error while doing OCR on PDF. while extracting the data I am getting an error "Attempted to read or write protected memory. This is often an indication that other memory is corrupt". Can you tell me solution regarding this issue. I am getting this error in following line:- string text = ocrApi.GetTextFromImage(bitmap.Image as Bitmap, rect); I want the solution Asap. Code is: Code:
InitWebApp();
OcrApi.LicenseKey = ConfigurationManager.AppSettings["LicenseKeyOcr"];
var ocr = OcrApi.Create();
MapperController mapperController = new MapperController();
double scaleFactor = 2;
foreach (var item in selChkList)
{
using (var doc = PdfDocument.Load(item))
{
List<Ocr> tempMetadata = mapperController.GetOcrMetadata(pdfTemplateId);
Dictionary<string, string> ocrTemp = new Dictionary<string, string>();
foreach (var itemdata in tempMetadata)
{
switch (itemdata.Language)
{
case "English":
ocr.Init(Languages.English);
break;
case "Hindi":
ocr.Init(Languages.Hindi);
break;
case "Marathi":
ocr.Init(Languages.Maharashtra);
break;
default:
break;
}
for (int i = 0; i < doc.Pages.Count; i++)
{
using (var page = doc.Pages[i])
{
string text = null;
if (doc.Pages[i] == doc.Pages[itemdata.PageIndex])
{
int width = (int)(page.Width * scaleFactor);
int height = (int)(page.Height * scaleFactor);
using (var bitmap = new PdfBitmap(width, height, true))
{
var lefttopCorner = page.PageToDevice(0, 0, (int)(page.Width), (int)(page.Height), PageRotate.Normal, itemdata.Left, itemdata.Top);
var rightbottomcorner = page.PageToDevice(0, 0, (int)(page.Width), (int)(page.Height), PageRotate.Normal, itemdata.Right, itemdata.Bottom);
page.Render(bitmap, 0, 0, bitmap.Width, bitmap.Height, PageRotate.Normal, RenderFlags.FPDF_LCD_TEXT);
var rect = new Rectangle(lefttopCorner.X, lefttopCorner.Y, rightbottomcorner.X, rightbottomcorner.Y);
text = ocr.GetTextFromImage(bitmap.Image as Bitmap, rect);
ocrTemp.Add(itemdata.Name, text);
}
}
}
}
}
CreateXML(item, ocrTemp);
}
}
Thanks in advance. Thanks and Regards Akshara. Edited by moderator Friday, July 14, 2017 4:52:46 PM(UTC)
