The commercial engine uses Highcharts for rendering. Since it's a commercial license, that is out of the question. So, for the Eclipse BIRT project to use anything else, we'd need to find a newer render engine that is open source and compatible with the Eclipse license. -John -------- Original message -------- From: Yair Lenga <yair.lenga@xxxxxxxxx> Date: 2/25/23 2:45 PM (GMT-06:00) To: birt-dev@xxxxxxxxxxx Subject: [birt-dev] Better Graphics Hi All,
The "original" open-source BIRT tool charting was based on a server-side Java charting tool - that delivered bitmap graphics (PNG, GIF or JPEG) - with fixed resolution. Somewhere around 10 years ago, the commercial package was enhanced with "HTML" graphic - basically SVG output from the same engine - which looked much sharper, generated smaller files, and allowed zooming. Does anyone have any idea what is involved in adding support for SVG output mode to the current Java charting package? I would like to move back to the open source - but the users hate the bitmap graphics - and creating high resolution charts (e.g., 300dpi or 600dpi) require XXXL files - takes forever to download and render. Thanks, Yair |
