fzoboli opened a new issue, #20981:
URL: https://github.com/apache/echarts/issues/20981
### What problem does this feature solve?
The current saveAsImage function in Apache ECharts allows users to download
charts as images, but the dimensions are based on the chart's display size in
the browser. This can lead to suboptimal image quality, especially on different
screen resolutions.
I propose adding options to specify the width and height for the downloaded
image. This would ensure images are always in an optimal format for printing or
sharing.
Benefits:
1. More control over image quality and dimensions.
2. Consistent representation of charts regardless of display size.
3. Enhanced usability for presentations and reports.
### What does the proposed API look like?
Example Usage:
`
saveAsImage({
type: 'png', // Image type
width: 800, // Desired width
pixelRatio: 1 // Image resolution
});
`
