Absolute dimension of slides and positioning objects on a slide

Aug 15, 2018

Hello,

I came across the discussion about the maximum size of images that are supported by Articulate Storyline (1, 2, or 3), which is 2048 px. I learned that lesson when I was dealing with some very long images in a scroll panel. I thought that I would get clever and chop the images into chunks that are at their maximum 2048 px in height. Inside the scroll panel, I manually typed in the vertical position that would allow my sequential images to appear stitched together.

At a quick glance, it seemed that everything was fine, but when I double-checked the final product, I noticed that my images were not positioned properly. They were much higher up than they should have been. I paid more attention to the value of the vertical position and it was resetting to 4000 px if I tried to exceed it.

I thought that was odd, so I did a little bit more testing. It turns out that +/-4000 px, both horizontally and vertically, are the maximum dimensions of any slide.

Now, you can cheat a little, because those values affect the position of the top-left corner (according to my tests). So, you could have an image with 2048 px of height at 4000 px vertical position inside of a scroll panel. That means that you can exceed the maximum dimensions of the slide (sort of).

What prompted my design choice of the scroll panel, was to simulate a webpage with a long list of names of contacts according to different business pillars. Now, I need to come up with a different solution.

I just thought that I would share this discovery, because I did not find any values listed in other discussions that combined both pieces together.

Thank you.

If you want to "cheat" the system, you can create a group, outside of the scroll panel, and make sure that its top-left corner is "higher" than the 4000 px vertical limit. (Groups cannot be created within scroll panels, but they can be dragged into them.)

  1. I created a simple rectangle and I moved it to Hor.:=0 and Ver.:=-4000.
  2. I pulled out the image that was causing me problems and positioned it 2 pages (2*2730px) below the rectangle [Hor.:=0 and Ver.:=1460].
  3. Once I created a group that contains the rectangle and the image, I dragged it back into the scroll panel.
  4. I adjusted the position of the top-left corner to match the first page in the scroll panel, and accounted for the 8px buffer that is added by groups.

When I tested my results, the appearance was seamless. I knew where the break was located and I had a hard time to find it.

So, if you create a group, you can have images and objects in your scroll panel that exceed the bottom edge of the working canvas of the slide.

I hope that others will find this a useful trick.

[I am assuming that the same thing will occur with horizontal scroll panels when the content exceeds the right edge of the canvas.]
