Connector Icon Lists

[bgribaudo]

Hello,

According to the docs, when defining "Publish" details for a data source, SourceImage and SourceTypeImage icons can be specified for the data source kind.

Each icon set is defined along the lines of:

MyIcons = [
    Icon16 = { Extension.Contents("HelloWorld16.png"), Extension.Contents("HelloWorld20.png"), ... },
    Icon32 = { Extension.Contents("HelloWorld32.png"), Extension.Contents("HelloWorld40.png"), ... }
];

However, the docs don't describe the difference between Icon16 and Icon32, or why each is set to a list of images (instead of each to a single image).

Questions: :-)

• What is the difference between Icon16 and Icon32?
  • Is Icon16 supposed to contain icons with a color bit depth of 16 and Icon32 images with a color depth of 32 bits?
  • If icons are specified, are both Icon16 and Icon32 required, or is it okay to only provide one or the other?
• Why provide a list of icons for each of the two fields?
  • Guessing this is to give the designer control over how an icon appears when displayed at different sizes: The designer provides several image files, each of different sizes. When displaying an icon, PQ/Power BI picks the image closest in size to the size it wants to display, then scales that image to the exact size needed (if necessary).
    • If correct, to help designers plan what size images to provide, what is the largest and smallest that an icon can be rendered?

Thank you!
