Re-using Xml ImageData

Is it possible to reference previous images in a following <Image /> tag when using the BindXml method?

In the following example, the image data is included in the XML twice. I would prefer to only include it once and reference the first instance when including the image a second time.

Re: Re-using Xml ImageData

Hi Jed,

Sorry for a delayed response.

Well, I am afraid; this feature is not supported at the moment. However, I have created an issue in our issue tracking system with issue id: PDFNEWNET-33271 for our development team to check if it is possible to implement such a feature. Once they investigate / analyze and share their feedback, I will update you via this forum thread.

Sorry for the inconvenience,

Re: Re-using Xml ImageData

Hello,

Is re-using the same image multiple times in the same PDF possible using the straight API? If so, can you point me to a simple example like the one I put together above, or can you adapt the sample above to do so using the API?

Thanks.

Hi Jed,

First of all I apologize for the delayed in response.

Kindly use the below mentioned code to reuse same imaged multiple time in the same PDF. Resultant file is also attaced for your analysis.

[C#]

Aspose.Pdf.Generator.Image image1 = new Aspose.Pdf.Generator.Image();
image1.ImageInfo.File = @"d:\pdffiles\aspose-logo.gif";
Aspose.Pdf.Generator.Segment seg1 = new Segment();
seg1.InlineParagraph = image1;
Aspose.Pdf.Generator.Pdf pdfConv = new Pdf();
Section sec1 = pdfConv.Sections.Add();
Aspose.Pdf.Generator.Table table1 = new Aspose.Pdf.Generator.Table();
sec1.Paragraphs.Add(table1);
Aspose.Pdf.Generator.Text text;
Aspose.Pdf.Generator.Segment newSeg;

for (int i = 0; i < 5; i++)
{
Aspose.Pdf.Generator.Row row1 = table1.Rows.Add();
text = new Text();
newSeg = new Segment(text);
text.Segments.Add(seg1);
row1.Cells.Add();
row1.Cells[0].Paragraphs.Add(text);
}

pdfConv.Save(@"d:\pdffiles\Image_in_Cell.pdf");

Please feel free to contact support in case you need any further assistance.
