Manuel Razzari <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #7 from Manuel Razzari <[email protected]> --- Given the historical importance of alt text for screen reader users [1], I'd say this is currently the #1 accessibility issue in PDF docs exported from Impress. I've verified an Impress PDF using the NVDA and JAWS screen readers, and using the "PDF Accessibility Checker" tool mentioned earlier in this ticket, and the problem is hugely noticeably. * One problem is that of missing text alternative, which causes that a lot of "meaningful" images in a presentation can't be properly conveyed to screen readers. [2] * A second problem is that decorative images, such as headers / footers / logos / background can't be marked as "purely decorative". So the screen reader will read a lot of "image image image", which it should simply be able to ignore. [3] (I reckon this may be worth of a separate bug.) Here's the help page [4] that confirms that the existing UI for "object title entry" is meant for specifically for this.
