Image compression in Rise

Hi

I'm having an issue with what appears to be an auto compression being applied to images I'm uploading to Rise.  It seems to be most obvious in images with text, as the text gets quite badly aliased.

I've attached a screen shot of how it appears in Rise, and the original PNG for comparison.  I did wonder if Rise was converting my PNGs to JPG, so I did try re-rendering as a 100% JPG but it ended up looking exactly the same despite the file size being around three times bigger.

Any ideas? 

Thanks! 

Nic

Hi Nicola,

Thanks for reaching out here and sharing those images (I did move your post to the Rise specific forum, since it's not in Beta, no worries on that!). 

I saw the same issues with pixelation when testing out your image, and our team is looking into some other examples of this so your images are helpful for our testing. I'll keep you posted on this here as I have more info to share.

As a more general FYI, I did want to make sure you had our best practices for working with images and other media in Rise. Let me know if you have any other questions and I'll share an update here as soon as I can!

Hi!

Is there any news regarding when this might be solved? We are also experiencing pixelated images, even when uploading images we've used in previous courses that looked great there but now looks horrible when we upload them again. A workaround is a lot of extra work (that obviously shouldn't be needed).

Hello Xtractor and welcome to E-Learning Heroes :)

Thank you for reaching out to share that you're running into this issue as well. It is still an open issue with our team, and if you have examples to share, that would be helpful. 

Are you using the workaround that Daniel shared above or did you find another?

For what it's worth, I've been creating chart images for a module that I'm working on. Originally, the charts were designed in Illustrator and were exported as PNGs. After importing them into Rise, I noticed the big drop in image quality. I have been doing graphic work before using Inkscape and couldn't recall seeing a similar issue, so I exported an SVG from Illustrator, opened it in Inkscape and exported it as a PNG. While there was a bit of a drop in image quality, it was nowhere near as noticeable as when I exported from Illustrator.

Although Inkscape renders the font as being thinner, I made a version with a thicker font to match Illustrator and the compression was still fine. While it would seem the solution is to use Inkscape over Illustrator, there are just some things I can't do in Inkscape and I even had to remove a couple of features/effects from the chart so I could give them an even test in both applications.

I'm having the same issues with automatic compression - even though I'm using png 24bit images.

Can we have the ability to set the compression like we do in storyline pls. Most of us are professionals and know how to compress the image in the first place, and we don't want the images to be compressed again.

Thanks!!!

Sure Ashley - have attached.

It seems to be mostly with flat solid colour graphics rather than photos. I think we can get away with a photo being a jpeg but when we use a .png file (24bit) it should be as crisp as the original....which its not, see examples.
