Problems with PDF-Export since version 2018.1.6

[tpontow]

Hello Stimulsoft-Team,

recently we switched from Stimulsoft version 2016.3.0.0 to version 2018.1.6.0. Since then we have some problems with PDF exporting Reports. We are using StiReport.ExportDocument() method.

We have nor changed our code for Export neither have we changed the Reports. We use the following method call:

Code: Select all

listReport.ExportDocument(StiExportFormat.Pdf, fileName, new StiPdfExportSettings {ImageQuality = 100.0f, ImageResolution = 300.0f,  })

One Report is stretched over more than one page. With this Report we got an error from the StiSegmentPagesDivider.

Code: Select all

Are there any known problems with PDF Export? Can you provide any help? Otherwise we have to go back to version 2016.3.0.0.

Thanks and Kind regards

Hi Thorsten,

We are not aware of this issue, do you mind to send a sample report template to support[at]stimulsoft.com for analysis, so we could reproduce the bug?

Thank you,
Edward

[Customer Explanation]

After rendering the Report in my C# code i opened the report in code with viewer (Report.Show(true)) and exported it to PDF using the viewer menu. I got that message (see below). When saving the Report to mdc-File and open that file with the Viewer and Export it to a PDF-file no error occurs.

If you load the attached mdc-file into a report in Code and then call

Code: Select all

StiReport rep = new StiReport();
rep.LoadDocument("ReportAsPDF.mdc");
rep.ExportDocument(StiExportFormat.Pdf, @".\ReportAsPDF.pdf", new StiPdfExportSettings { ImageQuality = 100.0f, ImageResolution = 300.0f, });

the error occurs.

I debugged in Stimulsoft source and found the Problem in

Code: Select all

StiSegmentPagesDivider: public static StiPagesCollection Divide(StiPagesCollection pages, StiExportService service)

Problem is line 137, soft cast to StiImage but then Access to property Border without null check.

Code: Select all

var needClip = !(service is StiPdfExportService);

#region Make new component
StiComponent newComp = null;
if (comp is StiContainer)
    newComp = comp.Clone() as StiContainer;

if (comp is StiText)
{
    var txtComp = comp.Clone() as StiText;
    if (needClip)
        txtComp.Text = string.Empty;

    newComp = txtComp;
}

//NULLREFERENCEEXCEPTION if comp is NO StiImage!!!
var cont = new StiContainer
{
    Border = (comp as StiImage).Border,
    Brush = (comp as StiImage).Brush
};

This is older code from version 2016.3 that we used before. Everything was ok then. I think there are significant changes made since then

Code: Select all

foreach (StiComponent comp in page.Components)
{
    if (comp.Enabled)
    {
        //if (rect.Contains(comp.Left, comp.Top))
        if ((rectX <= (decimal)comp.Left) && ((decimal)comp.Left < rectR) && (rectY <= (decimal)comp.Top) && ((decimal)comp.Top < rectH))
        {
            if (rect.Left == 0 && rect.Top == 0)
            {
                newPage.Components.Add(comp);
            }
            else
            {
                StiComponent newComp = comp.Clone() as StiComponent;
                newComp.Left -= rect.Left;
                newComp.Top -= rect.Top;
                newPage.Components.Add(newComp);
            }
        }
    }
}

newPages.Add(newPage);
