1361366 - SVG length precision too coarse

Status: RESOLVED DUPLICATE of bug 844258

(Core :: SVG, defect)

Description

[cousteau]

Attachment: Original file. Notice how the stars are not equally spaced vertically.

The attached SVG image shows a flag with a star pattern.  This pattern is generated in the SVG file by scaling down an original star path by a factor of 1/32.5, replicating it (with very precise displacement lengths), and then scaling it up 650 times.

However, it seems that Firefox uses a precision of 1/60 of a pixel for these lengths, so for example 0.0448 becomes 0.0333.  This 0.0115 px error may not seem like much but when multiplied by a scale factor of 650 it becomes more than 7 px, and after several accumulated errors the discrepancy in spacing sizes becomes apparent.

(I'm not sure if this should be fixed by Firefox or if the creator of the SVG is at fault for using such small scales, but it seems worth reporting.)

Attachment: This is how the previous SVG looks on my browser

Attachment: Same file except using a 1000x bigger scale; renders correctly.
