No images when creating PDF

Hi,
I need to save a report on the server side as a PDF.
For that I use the next code with javascript:
Code: Select all
var settings = new Stimulsoft.Report.Export.StiPdfExportSettings();
var service = new Stimulsoft.Report.Export.StiPdfExportService();
var stream = new Stimulsoft.System.IO.MemoryStream();
service.exportTo(report, stream, settings);
var data = stream.toArray();
let reportDataToServer = JSON.stringify(data);
After stringified the stream, I send that to the server, and I create PDF using C#
Code: Select all
var reportS = JsonConvert.DeserializeObject<String[]>(reportData);
var reportB = reportS.Select(byte.Parse).ToArray();
var randomcode = Utils.RandomString(10);
var path = ....
File.WriteAllBytes(path, reportB);
The problem that I have, as you can see on the example I attach ("ImageBar1.png"), the report has images that are used as "Headers" , that because I need to have some border radius on the upper corners.
After creating the report with the steps I mentioned, the PDF is not showing the images as you can see in the image "NoBars.jpg".
What do i need to solve this problem, or whats the correct way to save the report in an specific path in the server.
Im using Reports.JS.
Thanks

Hello,
Only async methods work for exports with pictures, it needs to convert pictures:
exportToAsync(onExport: Function, report: StiReport, stream: MemoryStream, settings: StiExportSettings)
exportTo2(report: StiReport, stream: MemoryStream, settings: StiExportSettings): Promise<void>
Thank you.

Hi,
It worked great. Thanks.
In case anyone needs to export and save on the server, the code I used at the end :
Javascript Code
Code: Select all
var settings = new Stimulsoft.Report.Export.StiPdfExportSettings();
var service = new Stimulsoft.Report.Export.StiPdfExportService();
var stream = new Stimulsoft.System.IO.MemoryStream();
await service.exportTo2(report, stream, settings);
var data = stream.toArray();
let reportData = JSON.stringify(data);
C# Code
Code: Select all
var reportS = JsonConvert.DeserializeObject<String[]>(reportData);
var reportB = reportS.Select(byte.Parse).ToArray();
var path = ....
File.WriteAllBytes(path, reportB);

Hello:
I'm trying to generate the pdf and I can't open it.
First I create a custom button
Code: Select all
createCustomButton(3, "TDC Mail", "/assets/img/logo-tdcmail-64px.png", function(){
viewer.onEmailReport({
format: 'pdf',
fileName: report.reportAlias,
data: GetDocumentExported('pdf'),
accion: '1'
});
});
Then call this function to handle the report type
Code: Select all
function GetDocumentExported(formato) {
var data;
switch (formato.toUpperCase()) {
case 'PDF':
data = createtPdf(report);
break;
case 'PPT2007':
data = createPpt(report);
formato = 'ppt';
break;
case 'HTML':
data = createHtml(report);
break;
case 'TEXT':
data = createTxt(report);
formato = 'txt';
break;
case 'WORD2007':
data = createDocx(report);
formato = 'docx';
break;
case 'ODT':
data = createOdt(report);
break;
case 'EXCEL2007':
data = createXlsx(report);
formato = 'xlsx';
break;
case 'ODS':
data = createOds(report);
break;
case 'CSV':
data = createCsv(report);
break;
case 'IMAGESVG':
data = createSvg(report);
formato = 'svg';
break;
}
return data;
}
Finally, if it is a PDF, call this last function.
Code: Select all
async function createtPdf(report) {
// Create an PDF settings instance. You can change export settings.
var settings = new Stimulsoft.Report.Export.StiPdfExportSettings();
var service = new Stimulsoft.Report.Export.StiPdfExportService();
var stream = new Stimulsoft.System.IO.MemoryStream();
await service.exportTo2(report, stream, settings);
//service.exportTo(report, stream, settings);
var data = stream.toArray();
return data;
}
The PDF is generated incorrectly, since I can't even open it.
What am I doing wrong?
Thanks in advance
