1216612 - SVG rendering: given a shape filled with a linear gradient, the gradient disappears when some transformation is applied

Status: RESOLVED WORKSFORME

(Core :: SVG, defect)

Steps to reproduce:

I created an SVG document (with viewBox="0 0 28000 21000") which contains a rectangle filled with a linear gradient (with gradientUnits="userSpaceOnUse"). A transformation is applied to the rectangle (transform="translate(1100 0) scale(0.25)").


Actual results:

The gradient fill is not shown. If I change the horizontal translation parameter from 1100 to 1000 the gradient fill is rendered correctly. To be exact every value greater than 1067 cause the gradient fill to not be rendered. Such a value depends on the scale value and the viewBox width (in a non-linear way). It does not depend on the rectangle position or size. When the scale parameter is >= 1 the gradient fill is rendered correctly. When `gradientUnits` is not set to `userSpaceOnUse` the gradient fill is rendered correctly.


Expected results:

The gradient should be rendered for any applied transformation even when gradientUnits="userSpaceOnUse".
