png-Image

[Lars]

Hello,
currently I have issues with pdf-rendering of reports using png-images in JS-Reports (Version: 2018.2.1).
The image boxes are empty (with static and dynamic loaded png-images).

Rendering of png in a HTML-view (preview) is working, but then aspect ratio with stretch isn't working there.

But: Pdf-rendering of jpg-images is ok (with static and dynamic loaded jpg-images, with aspect ratio and stretch, and in HTML-preview too).

Thank you

Could you upgrade to our latest build?
If you still get the issue, please, send us a sample that will help us to reproduce the issue.

Thank you.

Hello,
I can see the issue with png in current version too (2018.2.2).

Additional info: If I use the javascript-lib "pdf-js" to show such a bad pdf, then I can see pdf without the png and with additional warnings in Chrome debugger:
Warning: Native JPEG decoding failed -- trying to recover: Error during JPEG image loading
util.js:278 Warning: Unable to decode image: JpegError: JPEG error: SOI not found
util.js:278 Warning: Dependent image isn't ready yet

Perhaps, the png isn't correct embedded in the pdf?

Notes:
- Pdf-build by html-view is working (report -> htmlView -> pdf in browser):
using Stimulsoft.Viewer.StiViewer.renderHtml() and StiReport.print()

- Direct export (report -> pdf) with javascript/typescript is working only with jpg, but NOT with png:
using:

Code: Select all

            let settings = new Stimulsoft.Report.Export.StiPdfExportSettings();
            let service = new Stimulsoft.Report.Export.StiPdfExportService();
            let stream = new Stimulsoft.System.IO.MemoryStream();
            service.exportTo(report, stream, settings);

            let data = stream.toArray(); 

But we need direct export to avoid other issues with html-rendering.
Unfortunately our project is sophisticated and we have no easy sample.

Thank you

Hello,

PDF is supported images in jpg format.
To convert images in the JS version, you should use async method:
service.exportToAsync()

Thank you.
