I find the MouseOver Style “Image Filter” feature functional, but almost entirely useless given the non-standard output.
I know Axure generates this image swap by generating individual image assets on output instead of relying on CSS, but it makes no sense to me that the image calculations are so different than what all browsers support.
For example, the “Brightness” slider in Axure (with a range of -1 to +1) does not function at all like the “brightness” value in CSS:
https://developer.mozilla.org/en-US/docs/Web/CSS/filter
filter: brightness(0.4);
I would expect that Axure’s calculation to be the same, so that I can properly replicate what my images will look like once properly built in code.
