Tiddler rendering as node icon about tw5-tiddlymap

[felixhayashi]

Sorry @asampal

this is not possible.

Cecily does not produce miniture renderings but a its just the browser zoom. The graph can only contain images, its elements are not dom-elements. Also, there is not such a thing that I can create "screenshots" of tiddlers.

Nonetheless, it will be possible at some point to use images as graph nodes. But this is another milestone.

Felix, wrt Cecily I was just giving it as an example where you can see miniature or thumbnail tiddlers. The actual method for producing these would be by using something like html2canvas. This lib can take a document or div, say, and renders it to a canvas at 1:1 size. This can be resized using drawImage as shown here.

Another similar library is rasterizerHTML.js.

Hi @asampal,

thanks for the links. Still, to include this functionality is too special for this plugin (not saying this isn't a nice idea, it's just to special to be supported)

Here is how I envision such a case in the future:

1. A plugin xy (not written by me) periodically goes through all the tiddlers and creates snapshots.
2. The snapshots are referenced by tiddlers let's say via the icon field.
3. When drawing a graph, TiddlyMap looks at the icon field of a tiddler and uses this image to render the node.

My job is to ensure the last point. And as said above, I will work on that at a given point in time for sure.

Hi @asampal,

I you look at the examples at the demo site, the graph now uses images specified in the tiddler's icon field.

That's great Felix. Can they only be SVG images, though?

Hi @asampal,

No, I recently added support for all image mime types. So it can also be png. But only local images (stored in tw) are displayed and I cannot scale the image size in the graph, so you need scale it to the right size before adding it as icon.
