Status: RESOLVED FIXED

Since the fix for bug 373896, SVG text scales much better than before but it is still demonstrably less good than the Adobe plugin. The attached test case contains an SVG with some text which is scaled by a zoom event handler such that it should be rendered at a fixed size regardless of the zoom level. With the Adobe viewer, the text looks exactly right from the smallest to the largest zoom. But with Firefox the text can be seen to change in appearance as the image is zoomed.

Reproducible: Always

Steps to Reproduce:
1. Open the attached HTML and use the zoom buttons.
2.
3.
Actual Results:  
With Firefox, the text does not look exactly the same at different levels of zoom. The effect is most obvious at high levels of "zoom in" - i.e. small font sizes rendered at a large scale.

Expected Results:  
The text should not change at all as the image is zoomed.

It showed up malfunctioning when bug 370210 was fixed. Before that time the text mostly didn't show up (bug 369402 I think).

So it still worked fine before the fixes of bug 18333 and bug 369011 and then the text disappeared for nearly a month until bug 370210 was fixed.

Pleased to report this bug appears to be resolved since bug 392233 landed.

Excellent work as always gentlemen.

Close as WFM ?

Since we know the patch for bug 392233 fixed it we can close as FIXED rather than WFM.
