Feature Request: Configuring parameters for png export in embed mode

[hediet]

• I agree to follow the Code of Conduct that this project adheres to.
• I have searched the issue tracker for a feature request that matches the one I want to file, without success.

Is your feature request related to a problem? Please describe.
Some users of the Draw.io VS Code extension would love to set parameters when exporting or saving the diagram as png image. Most importantly, this includes the zoom parameter.

Describe the solution you'd like
If embedded mode consumers could specify the following parameters in the export action, I could implement that feature in the Draw.io extension:

This could look like this:

{
    action: "export",
    format: "xmlpng",
    zoom: 2, // by default 1
    dark: true, // by default false
    grid: false, // by default false
    borderWidth: 0, // by default 0
}

We'll add the following optional parameters in the next release: width (px) defines the width of the image to be exported, border (px) defines the border, shadow (boolean) specifies if a shadow filter should be applied to the export, grid (boolean) specifies if a grid should be added, keepTheme (boolean) specifies if the theme should be kept (eg. for dark themes), transparent (boolean) specifies if a transparent background should be used and background (string) specifies the background color.

Thanks! How can I set a zoom level if I don't know the dimensions? I think having both a fixed width export and a fixed dpi export would be useful.

Not sure if I understand: We'll have a width (in pixels) and a scale (zoom), do you need something else?

[hediet]

So you have a scale/zoom parameter? Then I'm happy ;) You didn't mention it in your listing.

It was already there. But yes. We're trying to document all the options here: https://www.diagrams.net/doc/faq/embed-mode
