Problem show image in PdfLightTable

Good afternoon

I need the image in the "Image" column on my grid

Code:

//string imageAsString = "/9j/4Rc7RXhpZgAATU0AKgAAAAgA.....";

byte[] data = new byte[imageAsString.Length];

MemoryStream stream = new MemoryStream(data);

PdfColumn colImagem = new PdfColumn("IMAGEM");

colImagem.StringFormat = new PdfStringFormat(PdfTextAlignment.Center, PdfVerticalAlignment.Middle);

colImagem.Width = 100;

tableColumns.Add(colImagem);

PdfColumn colCodigo = new PdfColumn("CÓDIGO");

colCodigo.StringFormat = new PdfStringFormat(PdfTextAlignment.Center, PdfVerticalAlignment.Middle);

colCodigo.Width = 40;

tableColumns.Add(colCodigo);

string Codigo = "ABC";

pdfLightTable.Rows.Add(new object[] { stream, Codigo);

It occurs that when sending to the PDF, it does not show the image.

This showing only the string "System.IO.MemoryStream...

Can someone help me....

Thank you

Hi Marcelo,

Thank you for contacting Syncfusion support.

We can able to add the image in PDF table cell by using BeginCellLayout event handler. Please refer the below code snippet for more details,

//Create a new PDF document

PdfDocument document = new PdfDocument();

//Add a page

PdfPage page = document.Pages.Add();

//Create a PdfLightTable

PdfLightTable pdfLightTable = new PdfLightTable();

//Create a data table

DataTable dataTable = new DataTable();

//Add columns to data table

dataTable.Columns.Add("Text");

dataTable.Columns.Add("Image");

//Add rows to data table

dataTable.Rows.Add("Adventure Cycle", "");

//Assign data source

pdfLightTable.DataSource = dataTable;

pdfLightTable.BeginCellLayout += pdfLightTable_BeginCellLayout;

pdfLightTable.BeginRowLayout += PdfLightTable_BeginRowLayout;

pdfLightTable.Style.ShowHeader = true;

//Draw light table to the page of PDF document

pdfLightTable.Draw(page, new RectangleF(0, 50, page.GetClientSize().Width, page.GetClientSize().Height));

Event handlers:

private void PdfLightTable_BeginRowLayout(object sender, BeginRowLayoutEventArgs args)

{

if (args.RowIndex == 0)

args.MinimalHeight = 100;

}

private void pdfLightTable_BeginCellLayout(object sender, BeginCellLayoutEventArgs args)

{

//Draw image in the same cell

if (args.RowIndex==0 && args.CellIndex == 1)

{

//Load the image as stream

Stream imageStream = typeof(App).GetTypeInfo().Assembly.GetManifestResourceStream("Sample.Assets.Image.jpg");

PdfBitmap image = new PdfBitmap(imageStream);

//Draw image

args.Graphics.DrawImage(image, args.Bounds.X, args.Bounds.Y , args.Bounds.Width, args.Bounds.Height);

}

Please try the above solution in your end and let us know the result.

Regards,

Good afternoon.

The example sent is working perfectly, but if there is more than one image does not appear the others. only the first image. In case I have a list of products with your images and as an example sent, it would be only for one image.

I need some help.

Thank you
