Hi,

We are using Aspose page PDF extraction method, But below specified method is extracting the text into Gibberish. Please have a look into it as a priority issue.

public PageContent Extract(Aspose.Pdf.Page page)
{
    var pageRect = page.GetPageRect(false);
    var size = new Size(pageRect.Width, pageRect.Height);
    var position = new Position(pageRect.LLX, pageRect.LLY);
    var pageRotation = (int)page.Rotate;

    var pageContent = new PageContent(page.Number, size, position, pageRotation);
    page.Rotate = Rotation.None;

    var tables = _tableCellExtractor.ExtractTables(page).ToList();

    var paragraphs = _paragraphExtractor.ExtractParagraphs(page, tables);
    foreach (var paragraph in paragraphs)
    {
        pageContent.AddParagraph(paragraph);
    }

    foreach (var tableCell in tables.Where(t => t.HasText).SelectMany(t => t.Rows.SelectMany(r => r.Cells)))
    {
        pageContent.AddCell(tableCell.CellArea);
    }

    return pageContent;
}

public IEnumerable<Table> ExtractTables(Page page)
{
    var absorber = new Aspose.Pdf.Text.TableAbsorber();
    absorber.Visit(page);
    return absorber.TableList.Select(ExtractTable);
}

private Table ExtractTable(AbsorbedTable table)
{
    var tableRectangle = Rectangle.FromAsposeRectangle(table.Rectangle);
    var rows = table.RowList.Select(ExtractRow).ToList();
    return new Table()
    {
        TableRectangle = tableRectangle,
        Rows = rows
    };
}

public IEnumerable<TextArea> ExtractParagraphs(Aspose.Pdf.Page page, List<Table> tables)
{
    var absorber = new ParagraphAbsorber();
    absorber.Visit(page);
    var markup = absorber.PageMarkups[0];
    var markupParagraphs = markup.Sections.SelectMany(s => s.Paragraphs);

    return markupParagraphs.SelectMany(p => PrepareParagraph(p, tables));
}

private IEnumerable<TextArea> PrepareParagraph(MarkupParagraph markupParagraph, List<Table> tables)
{
    var textAreas = ExtractTextAreas(markupParagraph, tables).ToList();
    ApplyWhiteSpaces(markupParagraph, textAreas);
    return textAreas;
}
