Import channels settings through URL parameters

[ShrimpCryptid]

Use Case

Preload certain settings per channel for sharing w/ default settings

Solution

?url=url1,url2&enabledChannels=[1,2]&c0=[...]&c3=[...]

Major URL parameters:

• URLs, comma separated and encoded
• List of enabled channels
• For each channel, a parameter c{n} where n is the index of that channel, starting from 0.
  • Value is a comma separated, key:value list. (Can also try JSON.)
  • Keys correspond to values in ChannelState, copied below:

    export interface ChannelState {
    name: string;
    volumeEnabled: boolean;
    isosurfaceEnabled: boolean;
    isovalue: number;
    colorizeEnabled: boolean;
    colorizeAlpha: number;
    opacity: number;
    color: ColorArray;
    controlPoints: ControlPoint[];
    }

Also, all of the advanced render settings:

• Mask cell
• Brightness
• Density
• Levels (3 values)
• Interpolate (boolean)
• Background color
• Bounding box (boolean)
• Bounding box color

Alternatives

Minimum is to support:

• Colorize
• LUTs w/ auto-IJ
  • [autoij, {n}]

Questions:

• Does autoij actually take a second parameter? (from looking through code it doesn't seem to?)
• ViewerChannelSetting also allows regex or string matching... do we only want to define raw channel indices?

[toloudis]

IIRC, the regex in viewerchannelsetting is partially for the purpose of creating groupings of channels in the UI. (e.g. all channels starting with "SEG_" go under a section called "Segmentation") I don't think we need that for the url parameters if it adds complexity.

[toloudis]

For autoij, I'm not sure what you mean by second parameter. If we have a min and max for each channel ,then we have to make a decision about how "autoij" should be encoded in that. I was just thinking to keep it simple put autoij in either one or both and if it is found in either one, it could override. This is also an opportunity to consider the naming of autoij with respect to #80
