setting the size (dimensions) of the image when saving

[perNyfelt]

I have a method that takes some kind of chart (created outside of my control) that i want to save to a file. It would be nice to be able to set the size (dimensions) of the image when saving either on the chart itself or on the BitmapEncoder but no such methods exists. Is there a way?

Thanks for the suggestion. As the library stands today this is not yet possible: a chart's width/height are set only at construction (via the builder), and there is no public setter or encoder parameter to override the output size at save time. So for a chart you receive from elsewhere, there is currently no clean way to pick the export dimensions.

We think this is a reasonable gap to close, so we'll leave this open as a feature request for a size-aware export API (likely overloads on ChartEncoder/BitmapEncoder that take an explicit width and height).

There is unfortunately no supported workaround at the moment that we can recommend, so for now the best path is to control the size where the chart is constructed if you have any influence there. We'll update this issue when the export-at-size API is available.
