I have been working on improving the fullscreen search functionality by implementing a preview mode. So now, there are two modes: _Grid_ and _Preview_. The preview mode is simply the grid but with a preview of the file’s contents. There will also by a third mode called _List_.

I experienced some serious performance issues after implementing this new preview mode. This is really what most of my time was spent trying to fix.

Before I was showing a real representation of the canvas where I rendered all the objects and scaled them to an appropriate size. Doing a full render of a canvas that could potentially contain 20 different objects (images, videos, note documents, etc.) is a bad idea. And it becomes an even worse idea if the search results include more than one canvas.

I decided to figure out a different solution that would solve the performance issues.
So I started experimenting… I figured that I could actually just show an image of the canvas, so I implemented functionality to take a snapshot of the canvas whenever closing a canvas file or switching to a different tab.

This works really well and I think I will choose the same approach for the minimap inside canvas files. Because currently, I am doing a full render of the objects inside a minimap and there is just no reason to do that… Instead I will just use the snapshot approach.

This means, I should also save a snapshot after making a change in the canvas, but of course with a debounce timer. For example, if moving an object, then take a new snapshot after a timer has expired.


Will share a video demonstrating of the fullscreen search later…
