Printing Flash Content in Firefox

February 24th, 2011 by Margaret Skomorokh

Flash and Firefox have always had a lot of compatibility problems – for instance, Flash content can’t be printed in Firefox.

A long time ago we found a workaround and published it as a free library. Three years have passed, but the bug still exists, and the fix is still relevant.

So here it is – a small library that allows to achieve correct Flash content printing in Firefox:
http://code.google.com/p/flash-print-fix/

For example, that’s how a Flex application is printed in Firefox:

And that’s how it looks like with the fix applied:

The idea is very simple:

1. Get a PNG screenshot.
2. Encode the PNG file in base64 string.
3. Add a picture with src=”data:img/png;base64,…” mce_src=”data:img/png;base64,…” to the page.
4. In CSS, specify to hide Flash while printing and to show the picture:

@media screen.flashScreenshot { display: none; }
@media print.printableFlashObj { display: none; };
.flashScreenshot { display: block; border: 0; outline: none; }

Knowledgebase Updates

Don’t forget that we have a knowledgebase: https://www.anychart.com/kb

We have already written about it before: https://www.anychart.com/blog/2009/06/30/anychart-knowledge-base

We do our best to update it as and when necessary and recently have added a few articles:

AnyChart

AnyGantt

We want to note that this problem: Documentation doesn’t display properly in Internet Explorer 7 and later has lost relevance in AnyChart 5.1.2.5

P.S. We are very pleased that our customers often find a minute to thank us and we have eventually added a testimonials page: https://www.anychart.com/company/testimonials.php

Thanks to everybody who has spoken out or not.

Flash Player Printing Bug Discovered

February 15th, 2011 by Margaret Skomorokh

During AnyGantt development, we have discovered a bug in the latest builds of Flash Player (existing since August 2010).

Here is a Flex example from the Adobe Help Resource Center:
http://livedocs.adobe.com/flex/3/html/help.html?content=printing_5.html

That’s how everything looks like in the original:

And that’s what happens to it after printing:





A long and persistent debugging has led us to isolating and reproducing the bug. In the simplest view, everything comes down to the following pictures:


(an original)


(the same after printing)

The source code of the example can be downloaded from:
https://bugs.adobe.com/jira/secure/attachment/68017/test_02_project_src.zip

The cause of the problem is the following: if the text in the Visual Objects tree has a parent object with “scrollRect”, there will be problems when printing to a bitmap.

The bug appeared supposedly in the version 10.1.82.76 of Adobe Flash Player, and it is also found in the current version (10.2).

We have submitted a bug report and now are waiting for the response:
https://bugs.adobe.com/jira/browse/FP-6167
