Images not displaying in pdf

image just shows in pdf as

aspose.pdf.Im
age@3b475a

I set the type and path as instructed in the documentation. Then I stream it back to the client but the image doesn’t display. instead I get

aspose.pdf.Im
age@3b475a

I am not providing any code because it seems my long posts with code get deleted.

Hi David,


Thanks for your inquiry. I’m afraid I couldn’t understand your issue. Could you please share some more details about your scenario?

Furthermore, we don’t have any restrictions on long posts. Please feel free to share your sample code/ document here.

Best Regards,

I set up my paths to the images like this.


HttpSession session = request.getSession();
String unitOfMeasure = (String) session.getAttribute(“unitOfMeasure”);
Integer projectId = Integer.valueOf(request.getParameter(“projectId”));
ServletContext sc = session.getServletContext();
String basePath = sc.getRealPath("/");
System.out.println(basePath);
Hashtable<String,String> imgH = new Hashtable<String, String>();
imgH.put(“GTS”, basePath + “\resources\images\GTS_humidifier.jpg”);
imgH.put(“VaporStream”, basePath +"\resources\images\VLC cover no Tknobs.jpg");
imgH.put(“XT”, basePath + “\resources\images\XT-VL4.jpg”);
imgH.put(“STS”, basePath + “\resources\images\STS_humidifier.jpg”);
imgH.put(“VaproMist”, basePath + “\resources\images\VM with VL4.jpg”);
imgH.put(“XTS”, basePath + “\resource/images\XTS.jpg”);
imgH.put(“CRUV”, basePath + “\resources\images\CRUV.jpg”);
imgH.put(“Ultra-sorb XV”, basePath + “\resources\images\US-XV.png”);
imgH.put(“Single tube”, basePath + “\resources\images\Single-Dispersion-Tube.png”);
imgH.put(“Ultra-sorb LV”, basePath + “\resources\images\Ultrasorb.png”);
imgH.put(“Mini-Bank”, basePath + “\resources\images\Mini-bank-humidifier.png”);
imgH.put(“Area-type”, basePath + “\resources\images\Area-type.png”);
imgH.put(“Ultra-sorb LH”, basePath + “\resources\images\US-LH.png”);
imgH.put(“Multi tube”, basePath + “\resources\images\Maxi-bank-humidifier.png”);
imgH.put(“Rapid-sorb”, basePath + “\resources\images\Rapidsorb.png”);
imgH.put(“SDU”, basePath + “\resources\images\SDUe.png”);
imgH.put(“Single Dispersion Tube”, basePath + “\resources\images\Single-Dispersion-Tube.png”);

and I use the hashtable as source for the following. adding images to table cells


Table table2 = new Table(sec1);

//Add the table in paragraphs collection of the desired section
sec1.getParagraphs().add(table2);

//Set with column widths of the table
table2.setColumnWidths(“72 72 72 72 72”);
table2.getDefaultCellTextInfo().setAlignment(AlignmentType.Center);

//Set default cell border using BorderInfo object
table2.setDefaultCellBorder(new BorderInfo(BorderSide.All.getValue(), 0.1F));

//Set table border using another customized BorderInfo object
table2.setBorder(new BorderInfo(BorderSide.All.getValue(), 0.5F));

//Create MarginInfo object and set its left, bottom, right and top margins
MarginInfo margin2 = new MarginInfo();
margin2.Left = 0.5f;
margin2.Right = 0.5f;
margin2.Top = 0.5f;
margin2.Bottom = 0.5f;
//Set the default cell padding to the MarginInfo object
table2.setDefaultCellPadding(margin2);
int imageAddedCount = 0;
String uniqueProducts = “”;
row = table2.getRows().add();
for(int j = 0; j< schedList.size(); j++)
{
sched = (Schedule) schedList.get(j);
if(sched.getGenerationProduct() != null && uniqueProducts.indexOf(sched.getGenerationProduct()) < 0)
{
aspose.pdf.Image img = new aspose.pdf.Image();
String imagePath = imgH.get(sched.getGenerationProduct());
if(imagePath.substring(imagePath.indexOf(".") + 1 , imagePath.length()).compareToIgnoreCase(“jpg”) ==0 )
{
// Specify the Image file type as JPEG
img.getImageInfo().setImageFileType(ImageFileType.Jpeg);
}
else if(imagePath.substring(imagePath.indexOf(".") + 1, imagePath.length()).compareToIgnoreCase(“PNG”) == 0)
{
img.getImageInfo().setImageFileType(ImageFileType.Png);
}

//Set the path of image file
img.getImageInfo().setFile(imagePath);
row.getCells().add(sched.getGenerationProduct() + “\n” + img);
uniqueProducts = uniqueProducts + sched.getGenerationProduct();
imageAddedCount++;
}
if(sched.getDispersionProduct() != null && uniqueProducts.indexOf(sched.getDispersionProduct()) < 0)
{
aspose.pdf.Image img1 = new aspose.pdf.Image();
String imagePath = imgH.get(sched.getDispersionProduct());
if(imagePath.substring(imagePath.indexOf(".") + 1 , imagePath.length()).compareToIgnoreCase(“jpg”) ==0 )
{
// Specify the Image file type as JPEG
img1.getImageInfo().setImageFileType(ImageFileType.Jpeg);
}
else if(imagePath.substring(imagePath.indexOf(".") + 1, imagePath.length()).compareToIgnoreCase(“PNG”) == 0)
{
img1.getImageInfo().setImageFileType(ImageFileType.Png);
}

//Set the path of image file
img1.getImageInfo().setFile(imagePath);

row.getCells().add(sched.getDispersionProduct() + “\n” + img1);
uniqueProducts = uniqueProducts + sched.getDispersionProduct();
imageAddedCount++;
}
if(imageAddedCount % 5 == 0)
{
row = table2.getRows().add();
}
}

and I stream back to the client as


ServletOutputStream stream = null;
byte buf1[] = null;
try
{
stream = response.getOutputStream();
response.setContentType(“application/pdf”);
response.addHeader(“Content-Disposition”, “attachment;Filename=schedule.pdf”);
buf1 = pdf1.getBuffer();
response.setContentLength(buf1.length);
int readBytes = 0;
for(int i = 0; i < buf1.length; i++)
{
readBytes = buf1[i];
stream.write(readBytes);
}

}
catch (IOException ioe)
{
throw new ServletException(ioe.getMessage());
} finally
{
if(stream != null)
{
stream.flush();
stream.close();
}
if(buf1 != null)
{
buf1 = null;
}
}

and what appears in my exported pdf table is


aspose.pdf.Im
age@1f2380


in place of the actual image

So I left all that code overnight hoping for a response. But come in this morning to find no response. It is bad enough that I have to wait overnight to get response to my questions, but now no response after overnight even. What I am I doing wrong?

Hi David,

Does this mean no one has ever tried to do what I am doing? Creating a pdf from scratch and putting images in it?
