When you upload an image to Bramble, we make it is a big as possible whilst maintaining its aspect ratio and ensuring it all fits on the page. That means if you upload a portrait image or PDF, it will appear on the left hand side of the screen in a split screen view.
If you’d like the resource to appear differently, I’d recommend using screenshot to select the portion of the document you want to share and then pasting that in. That should effectively enable you to ‘zoom in’ on a resource.
We’ve put together a demo notebook which hopefully illustrates that a bit more clearly: https://content.bramble.io/exports/WillChambers6567-QEZc.pdf
There are some more details here too.
and a video to show how:
Alternatively, on many laptops you can use the trackpad to zoom in on the screen. Here's a help article showing how it works on Mac but the same gestures apply on many Windows laptops too: https://support.apple.com/en-us/HT204895
If you would like to manipulate how resources look in the Bramble room, we have a very handy tip. Conveniently the size of a Bramble page is very similar to that of a powerpoint slide. So a great way of doing things is to prepare your lesson beforehand in a powerpoint presentation, where you can choose exactly how everything is displayed. Once you have finished just make sure you save the powerpoint as a PDF.
Then, within your live session, you can quickly upload your powerpoint PDF in the room in a matter of seconds without it disrupting the flow of the lesson.
