Image Sizing

[Richard Brown]

I have a logo which renders at one size in the web report viewer and a much smaller size when exporting to PDF from the web viewer.  Any suggestions as to how to make them the same or at least close?

Hi Richard,

The PictureBox behavior can be modified by specifying different kinds of Sizing mode: AutoSize, Center, Normal, Stretch and ScaleProportional. You can try the different settings to see whether you can achieve a better result.

It's also possible that the problem is in the resolution of the image. While the Image rendering (PDF, TIFF) respects the image's resolution, the browser shows the image according to its pixels. In this way an image with a greater resolution becomes larger in a browser. To fix this problem you should use images either with the resolution of the screen or set the Sizing mode to Stretch or ScalePropoprtion with a fixed size of the PictureBox item.

Hope this helps.

That does the job.  Thanks!

Tried the suggested solution. Still the stretching is not proportional.

Hello RK,

Where do you observe the problematic behavior - does it occur when viewing a report in a report viewer or in a specific export format (e.g. PDF, RTF etc.). How is the PictureBox item getting the image? As we have not been able to reproduce the problem in our local tests, we would appreciate if you provide us with as much info as possible and possibly with a report that exhibits the issue.

Kind regards,

Hello, please see my answers below:

Where do you observe the problematic behavior - does it occur when viewing a report in a report viewer or in a specific export format (e.g. PDF, RTF etc.).

Yes, this is when I export the report onto PDF. I cannot see the report contents on the screen because this is a large report having about 900 pictures placed in the report.


How is the PictureBox item getting the image?
Here is the sample
 //----------------------------------------------------------------------------------------
                string filePath = Server.MapPath("ImagesParts");
                filePath = Path.Combine(filePath, inf.PartNumber + ".jpg");
                if (false == File.Exists(filePath))
                {
                    filePath = Server.MapPath("ImagesParts");
                    filePath = Path.Combine(filePath, "PhotoUnavailable.jpg");
                }
                if (File.Exists(filePath))
                {
                    data = File.ReadAllBytes(filePath);
                    inf.FileContent = data;
                }
 //----------------------------------------------------------------------------------------

 As we have not been able to reproduce the problem in our local tests, we would appreciate if you provide us with as much info as possible and possibly with a report that exhibits the issue.

Hi RK,

Thanks for the additional info, however we're still not able to observe such behavior locally. Please open a support ticket and attach a small sample report with a single image that exhibits the problem.

My support package is no more active. So, I cannot create a support ticket online.

Hello RK,

Create a sample, remove all Telerik assemblies, zip it and attach it to one of the many free file servers and give us a link here. In this line of thoughts, what is the Telerik Reporting version you use?

All the best,

Hi,

Here is the link to download the files

https://oceaneering.sharefile.com/d/s628aa5019a341349

Please let me know if you have any problems to download this.

Check default aspx and default.cs and App_Code/RptTelerik.cs, as the report file

I have also attached the 2 sample original images and the sample pdf report that uses those images.

BTW, the report version is 'Telerik Reporting Q2 2011', version 5.1.

Thanks.

Hello RK,

I did not understand what is wrong with PictureBox Sizing modes. You can see a demo movie in the attached file ImageResizingExample.zip. Also see the simplified version of your report in the attached project.

Do you have a later version of Telerik report  Component that will address this issue?

Also, in the report file, please see that the page is not skipped even after PageBreak property is set to 'Before' for the group header.
