Hello,
We’re trying to convert a (pseudo-)random document to a PDF/A file. Obviously, this will not be possible, since there are restriction. In our current test, we’re working with an Excel file (xlsx) and trying to convert it to a PDF/A 1B file.
We do this using the direct method - save it a pdf and passing PdfSaveOptions - and by first converting it to an tiff and then to a pdf.
The success boolean coming from the convert method claims it went successful, although the pdf tool validator still claims it is not a valid PDF/A. (http://www.pdf-tools.com/pdf/validate-pdfa-online.aspx)
The sample file is attached to the post.
We’re running it on a Windows 7 x64, using .NET Aspose PDF 10.5 and Cells 7.7.2.
The sample code is as follow:
// Load the file
Aspose.Cells.Workbook book = new Aspose.Cells.Workbook(@“C:\Input.xlsx”);
// Convert it directly
book.Save(@“C:\Output 1.pdf”, new Aspose.Cells.PdfSaveOptions() { Compliance = Aspose.Cells.Rendering.PdfCompliance.PdfA1b });
// Convert to a TIFF, and then a PDF/A
using (MemoryStream stream = new MemoryStream())
{
Aspose.Cells.ImageSaveOptions options = new Aspose.Cells.ImageSaveOptions(Aspose.Cells.SaveFormat.TIFF);
options.ImageOrPrintOptions.TiffCompression = Aspose.Cells.Rendering.TiffCompression.CompressionLZW;
book.Save(stream, options);
Bitmap bmp = new Bitmap(stream);
Aspose.Pdf.Document pdf = new Aspose.Pdf.Document();
Aspose.Pdf.Page page = pdf.Pages.Add();
page.PageInfo.Margin.Bottom = 0;
page.PageInfo.Margin.Top = 0;
page.PageInfo.Margin.Left= 0;
page.PageInfo.Margin.Right= 0;
page.CropBox = new Aspose.Pdf.Rectangle(0, 0, bmp.Width, bmp.Height);
Aspose.Pdf.Image img = new Aspose.Pdf.Image();
page.Paragraphs.Add(img);
img.ImageStream = stream;
bool success = pdf.Convert(@“C:\Convert Log.xml”, Aspose.Pdf.PdfFormat.PDF_A_1B, Aspose.Pdf.ConvertErrorAction.Delete);
pdf.Save(@“C:\Output 2.pdf”);
}
Are we doing something wrong, overlooking something, or does Aspose simply claim a file to be PDF/A, while it does not meet the standard?
Thanks in advance,
Jeroen
