Problems converting charts to images


I tried to create various chart images via the ToImage() function and noticed the following problems:

3-D format, shadow and rich text formatting seems to be not supported for chart-to-image conversion. (chart 1, chart 2) When will these features be supported?

After conversion, there is a whitespace missing between ‘important’ and ‘word’. (chart 1)

The rendering of charts 2 and 3 are not proper.

Comparing Excel charts and image there are differences in the distances between legend entries. (chart 3 , chart 4)

Positioning of the pieces in Pie charts after conversion is not ok. (chart 3)

The position of trendline label in exported images is always the same. (chart 5)

Thanks in advance!
