Chart export resolution

[Mick]

Is there any way to export a chart at different resolutions? I think the default is 72 or 96, but I want something higher, like 300.

There is an overload to the method that seems like it might work, but it is not documented in the help file:

Chart.Export(FileFormat format, Stream stream, object settings).

Thank you,

The bad news is that current builds are hardcoded to use 96 dots per inch.

The good news is that as you already noted, there is an Export overload that receives a settings object. You can use an object of type ExportImageSettings to customize the image generation process (sorry for the lack of docs), builds marked 3733 or later will support a DPI property to allow you to change the image resolution.

The change is very small so the new build should be available in a day or two.

 Is this feature in 8.0.3733.27808?

Where would I look for it?

I looked here:

(new Chart()).DPI // <- not here

(new Chart()).Export(FileFormat.Png, new MemoryStream(), 300); // <- Not here

---

As an alternative, you stated that the ExportImageSettings can customize the image generation process. How would I use this in the mean time if the DPI is not there yet?

Thank you,

You need something like

ExportImageSettings settings = new ExportImageSettings();

settings.DPI = 300;

and then use settings as the last parameter in the Export call that receives an extra object parameter. The class ExportImageSettings existed before but the DPI member was added in build 3733
