Can't print jpg with Aspose.Pdf

I want to load in a JPEG file and print it with Aspose.Pdf in C# (.net Framework 4.8). The code I currently have is:
public void PrintImage(string fileToPrint, string printerName, string jobName)
{
System.Drawing.Image srcImage = System.Drawing.Image.FromFile(fileToPrint);
int h = srcImage.Height;
int w = srcImage.Width;
var doc = new Document();
var page = doc.Pages.Add();
var image = new Image();
image.File = (fileToPrint);
page.PageInfo.Height = (h);
page.PageInfo.Width = (w);
page.PageInfo.Margin.Bottom = (0);
page.PageInfo.Margin.Top = (0);
page.PageInfo.Margin.Right = (0);
page.PageInfo.Margin.Left = (0);
page.Paragraphs.Add(image);
var viewer = new PdfViewer(doc);
PrintUsingViewer(viewer, printerName, jobName);
}
private static void PrintUsingViewer(PdfViewer viewer, string printerName, string jobName)
{
viewer.AutoResize = true; // Print the file with adjusted size
viewer.AutoRotate = true; // Print the file with adjusted rotation
viewer.PrintPageDialog = false; // Do not produce the page number dialog when printing
var ps = new System.Drawing.Printing.PrinterSettings();
var pgs = new System.Drawing.Printing.PageSettings();
ps.PrinterName = printerName;
viewer.PrinterJobName = jobName;
viewer.PrintDocumentWithSettings(pgs, ps);
viewer.Close();
}
When I save the document instead of printing and look at it, it seems fine (the image is added). However, when trying to print the image it is not printed and the page is just blank..
I would like to print without first saving the document as a PDF and then trying to print that saved PDF. Does anyone see what I am doing wrong?

The solution was adding this line of code
doc.ProcessParagraphs();
right after this line:
page.Paragraphs.Add(image);
So the code now becomes
public void PrintImage(string fileToPrint, string printerName, string jobName)
{
System.Drawing.Image srcImage = System.Drawing.Image.FromFile(fileToPrint);
int h = srcImage.Height;
int w = srcImage.Width;
var doc = new Document();
var page = doc.Pages.Add();
var image = new Image();
image.File = (fileToPrint);
page.PageInfo.Height = (h);
page.PageInfo.Width = (w);
page.PageInfo.Margin.Bottom = (0);
page.PageInfo.Margin.Top = (0);
page.PageInfo.Margin.Right = (0);
page.PageInfo.Margin.Left = (0);
page.Paragraphs.Add(image);
doc.ProcessParagraphs();
var viewer = new PdfViewer(doc);
PrintUsingViewer(viewer, printerName, jobName);
}
private static void PrintUsingViewer(PdfViewer viewer, string printerName, string jobName)
{
viewer.AutoResize = true; // Print the file with adjusted size
viewer.AutoRotate = true; // Print the file with adjusted rotation
viewer.PrintPageDialog = false; // Do not produce the page number dialog when printing
var ps = new System.Drawing.Printing.PrinterSettings();
var pgs = new System.Drawing.Printing.PageSettings();
ps.PrinterName = printerName;
viewer.PrinterJobName = jobName;
viewer.PrintDocumentWithSettings(pgs, ps);
viewer.Close();
}
Now the image is printed correctly!

Loading tsv/csv file in excel sheet

This is my code.
public static string LoadPackage(DirectoryInfo outputDir, string name)
{
FileInfo newFile = new FileInfo(outputDir.FullName + #"\test.xlsx");
if (newFile.Exists)
{
newFile.Delete();
newFile = new FileInfo(outputDir.FullName + #"\test.xlsx");
}
var format = new ExcelTextFormat();
format.Delimiter = '\t';
format.SkipLinesBeginning = 1;
using (ExcelPackage package = new ExcelPackage())
{
LoadSheet(package, outputDir, name);
package.SaveAs(newFile);
}
return newFile.FullName;
}
And after that i call LoadSheet method in order to fill my excel file from tsv file.
public static void LoadSheet(ExcelPackage package, DirectoryInfo
outputDir, string name)
{
var ws = package.Workbook.Worksheets.Add("Content");
var format = new ExcelTextFormat();
format.Delimiter = '\t';
format.SkipLinesBeginning = 2;
format.SkipLinesEnd = 1;
var range = ws.Cells["A1"].LoadFromText(new
FileInfo(outputDir.FullName + "\\" + name), format,
TableStyles.Medium27, false);
}
And this is my code on button click event
if (BrowseFileUpload.HasFile)
{
var name = BrowseFileUpload.PostedFile.FileName;
InputTextBox.Text = name;
LoadData.LoadPackage(new
System.IO.DirectoryInfo("C:\\Users\\Nemanja\\Downloads"), name);
InfoLabel.Text = "Your data has been imported!!!";
InfoLabel.ForeColor = System.Drawing.Color.Blue;
InfoLabel.Font.Size = 20;
}
Everything is ok i create new excel file, sheet save it but it does not load data that i need it to load inside excel file. It's only empty file or i get a error the file is corrupted recover what you can.
Can someone figure out what can be a problem based on my explanation and this code. Thank you all good people.

I think that the problem may well be with the format of your source data. I've put together the following sample, based on your code, and it works fine.
var outFile = Path.ChangeExtension(filePath, ".xlsx");
using (var p = new ExcelPackage())
{
var fmt = new ExcelTextFormat();
fmt.Delimiter = '\t';
fmt.SkipLinesBeginning = 2;
fmt.SkipLinesEnd = 1;
fmt.EOL = ((char)10).ToString(); // THIS LINE FIXED THE PROBLEM (UNIX NEWLINE)
var ws = p.Workbook.Worksheets.Add("Imported Text");
ws.Cells[1, 1].LoadFromText(new FileInfo(filePath), fmt, TableStyles.Medium27, false);
p.SaveAs(new FileInfo(outFile));
}
Try running your data through this and see if you get the same issue or not.
UPDATED
The problem was a unix-style newline in the file - EPPlus expects a windows-style newline by default

I have a sub-report on my rdlc report,, when i tried to export it to excel. The error message appear on excel file (sub-report section).
"Data retrieval failed for the subreport, 'srAvailabilityList', located at: C:\Users\xxxxx\Documents\Visual Studio 2010\Projects\coco\rdlc\availabilityreading.rdlc. Please check the log files for more information."
The sub-report is using ds6 and ds7.
My questions are:
How can I retrieve the data in the sub-report?
Where I can find the log files?

Found the answer:
void MySubreportEventHandler(object sender, SubreportProcessingEventArgs e)
{
var operationDate = System.DateTime.ParseExact(txtStartDate.Text, "dd/MMM/yyyy", CultureInfo.CurrentCulture);
var ds6 = new _spAvailabilityDailyReportTableAdapter();
var ds7 = new _spAvailabilityReadingTotalTableAdapter();
var rds6 = new ReportDataSource("dsAvailabilityDailyReport", (DataTable)ds6.GetData(operationDate)); //isi data report di parameter kedua
var rds7 = new ReportDataSource("dsAvailabilityReadingTotal", (DataTable)ds7.GetData(operationDate)); //isi data report di parameter kedua
e.DataSources.Add(rds6);
e.DataSources.Add(rds7);
}
Then add this code before report.SetParameter :
report.SubreportProcessing += new SubreportProcessingEventHandler(MySubreportEventHandler);

Dynamically Insert Image to PDF using LiveCycle/ITextSharp

I have a pdf template I created using LiveCycle Designer. Inside it, I have 3 Image Fields that I created, ImageField1, ImageField2, ImageField3. The images are located on a url, let's call it "http://images.com/img/IMAGENAME.jpg", and the user selects the images prior to generating the pdf in which case I store the image names in a string array.
Is it possible to add these images programmatically into the Image Fields? The methods I've tried so far have only lead to a corrupted pdf that won't open at all.
public string Foo(int id)
{
try
{
var file = string.Empty;
var property = ((IRepositoryBase)PropertyRepository).GetById<Property>(id);
var purchase = ((IRepositoryBase)PropertyRepository).GetByPropertyId<PropertyPurchase>(id);
var inspection = ((IRepositoryBase)PropertyRepository).GetByPropertyId<PropertyInspection>(id);
file = HttpContext.Current.Server.MapPath("\\Assets\\documents\\originals\\Brochure.pdf");
var tmp = HttpContext.Current.Server.MapPath("\\Assets\\documents\\temps\\");
tmp += string.Format("{0}-Brochure.pdf", property.Id);
var pdfReader = new PdfReader(file);
var pdfStamper = new PdfStamper(pdfReader, new FileStream(tmp, FileMode.Create));
var pdfFormFields = pdfStamper.AcroFields;
var pht = property.BrochurePhoto;
string[] photos = pht.Split(' ');
PdfContentByte cB = new PdfContentByte(pdfStamper.Writer);
if (photos[0] != null)
{
iTextSharp.text.Image photoToPdf1 = iTextSharp.text.Image.GetInstance(new Uri("http://images.com/img/" + photos[0].ToString() + ".jpg"));
cB.AddImage(photoToPdf1);
}
if (photos[1] != null)
{
iTextSharp.text.Image photoToPdf2 = iTextSharp.text.Image.GetInstance(new Uri("http://images.com/img/" + photos[1].ToString() + ".jpg"));
cB.AddImage(photoToPdf2);
}
if (photos[2] != null)
{
iTextSharp.text.Image photoToPdf3 = iTextSharp.text.Image.GetInstance(new Uri("http://images.com/img/" + photos[2].ToString() + ".jpg"));
cB.AddImage(photoToPdf3);
}
pdfStamper.FormFlattening = false;
pdfStamper.Close();
return string.Format("{0}-Brochure.pdf", property.Id);
}
catch (Exception ex)
{
Log.Error(ex);
return string.Empty;

Call the SSRS report in button click and need to get the output as PDF file

I had an grid view where I had placed an link button to print an report. In this button click event I need to call the SSRS report and need to get the output as PDF file.
I had used this below code,the code is running fine, but I'm unable to see the prompt to open/save pdf file.
