Drawing Image from Stream to PdfGrid cell

[Andreas Hirtzel]

Hi,

I'd like to insert an image from a byte stream to a PdfGrid cell.
Here is my code:

Image img;
using( MemoryStream ms = new MemoryStream() )
{
ms.Write(imgByteArray, 0, imgByteArray.Length);
ms.Seek(0, 0);
img = Image.FromStream(ms, true);
}
PdfBitmap pBmp = new PdfBitmap(img);
pGrid.Rows[0].Cells[0].Value = pBmp;

The cell where the image should reside is empty. What is wrong?

Hi Andreas,

Thank you for your interest in Essential PDF.

Drawing image in PdfGrid
I am able to see the issue that you have mentioned here. But this can solve by using BackgroundImage property of the PdfGrid.

Could you please try the below code snippets in your sample and let me know if this helps,

PdfBitmap pBmp = new PdfBitmap(@"..\..\Data\pdf_button.png");
pGrid.Rows[0].Cells[0].Style.BackgroundImage = pBmp;
pGrid.Rows[0].Cells[0].Value = "";

Regards,
Suba

Hi Suba,

thank you for reply. Your suggestion works great. With stream, too. Here is the code:

Image img;
MemoryStream ms = new MemoryStream();
ms.Write(imgByteArray, 0, imgByteArray.Length);
img = Image.FromStream(ms, true);
PdfImage pBmp = new PdfBitmap(img);
pGrid.Rows[0].Cells[0].Style.BackgroundImage = pBmp;
pGrid.Rows[0].Cells[0].Value = "";

Thanks!

Hi,

I hadf to span the image over some cells, now. The problem is, that the image has the same size as the merged cells has. Is there an other way to draw an image in a grid cell?

Hi Meiyappan,

this is, what I have done before. Run your sample and look at the image in cell and compare it with the original image file. You'll see, it is stretched. I think, there must be an other way to draw an image in PdfGrid cell.

Andreas

Hi Andreas,

Sorry for the delay caused in getting back to you.

We are able to see that the image is stretched.For drawing the image in its exact size we have to manually set the columns width and height same as the width and height of the image.

Kindly let us know if you have any concerns.

Hi Andreas,

Could you please download the sample from the below link in which the dimensions of the rows and columns are set manually so that the image size is preserved in the Grid cell.

Kindly let us know if you have any questions.

I'm working with a PDFGrid and I need to embed an Icon in a cell that plays a sound annotation.

I was given an example where the SoundAnnotation needs to be placed by giving it an x,y coordinates which is not an option as I won't be able to always accurately place it in the right cell if the pdf paginates.

any suggestions?

            var dt = new DataTable();

            dt.Columns.Add("column1");

            dt.Columns.Add("column2");

            dt.Columns.Add(" ");

            foreach (var question in questions)

            {

                 var dr = dt.NewRow();

                dr[0] = question.remark;

                dr[1] = "";

                dr[2] = question.answer; //I would like place here an icon that play the sound annotation

                dt.Rows.Add(dr);

            }

            var questionFrame = new PdfGrid();

            questionFrame.DataSource = dt;

            questionFrame.Columns[1].Width = 25;

            questionFrame.Style.Font = _fontSpecs;

            questionFrame.Style.TextBrush = _grayBrush;

            questionFrame.Style.CellPadding.Top = questionFrame.Style.CellPadding.Bottom = 5f;

            questionFrame.Style.CellPadding.Left = 5;

            questionFrame.Style.CellPadding.Right = 5;

            foreach (PdfGridRow header in questionFrame.Headers)

            {

                foreach (PdfGridCell cell in header.Cells)

                {

                    cell.Style.Borders.All = PdfPens.White;

                    

                }

                header.Style.Font = _boldFontStyle;

                header.Style.TextBrush = _blackBrush;

                header.Cells[1].ColumnSpan = 2;

            }

Hi Bill,

Thank you for using Syncfusion Products.

We could not able to directly draw the PdfSound Annotation in to the PdfGrid cell, we have to manually calculate the coordinate values. However this can be achieved only in PdfLightTable by using the Event Handlers. Please find below the online sample link for how to use the event handlers.

Please let us know if you need any further assistance.
