I hope I can explain this clearly...

When I resize (downscale) images in my graphics package it is able to generate a smaller resolution image that still looks crisp. In Xerte I needed a hotspot image that was actually a screen grab of text. I found that if I inserted a high resolution image it got rescaled in Xerte but looked blocky. I couldn't find any information about the ideal jpeg resolution for in Xerte so played around until I came up with a resolution that looked crisp. This can be seen in the 'defaultsize' attached image.

However, in a recent session someone switched to the full screen view, and the text now looked horribly blocky (see other attached image). Obviously any image will be blocky when enlarged beyond its default resolution. However, since we can't control the size at which the user views a Xerte object (even though we can set the default appearance of it to full screen), it would be great if we could upload an image at a relatively high 'recommended' resolution (whatever that is) and for Xerte to automatically downscale it as appropriate. Are there any plans to improve the scaling algorithms in Xerte so that this would work better, giving a clear image at whatever size the object is viewed?

I hope that makes sense!

Many thanks,
Karl
