Re: role="text" and text frames

I ran this by Freedom Scientific and if a role is chosen they agree it ought to be for STATIC text. 

So, this is bigger than just an image. In SVG the author can draw text using drawing strokes. By applying a role of text you can determine the text being drawn and we could make it searchable. 

If we make this the text role the AT should have enough knowledge that it is either a raster image or a vector drawing and that the text equivalent for the text drawn is what is to be rendered. Static text is important in that it would allow the text to be read to the user when placed in a line of text. Text frame would not work that way. It would be treated as a separate entity much the same way we handle TDs when role=“presentation”  is applied to a  table. 

I don’ agree that the text role can be ignored. I think that would be very bad - especially in the case of SVG.

The text role is not making a case for removing the image, but instead saying that authors should have a way to hint that screen readers may want to read the image as text. The text role is based on the premise, I think, that this is more friendly to screen reader users when reading. I personally do not regard it as more friendly to me, but that is a personal choice.

Similarly, if I am reading a text for school, and if part of the discussion is the author's use of imagery, then I would not be part of the discussion if the publisher of the document used the text role for all the images embedded in the text.

Again, this is radically different from presentational images, which,by the way, screen readers can choose to see if they want. I can tell my screen reader to show all images, even those with no alt text.

See the final text in Rich's email for the ACTION-1380 effort [1].  If a presentational image allows interaction with a context menu, then, Houston, we have a problem, since there in no accessible in the AAPI to hang that menu off of.
