(wording my issue with a proper human language): when i import any svg shapes that use
gradient i either have a solid color (that's how i discovered it) or no color at all
(discovered when making sure that it appears everywhere)
1st img: original shape & color ffdec
2nd img: original shape & color figma

actually i'll add it there
when not edited it imports perfectly well

Please attach the SWF file and the SVG file you are trying to import and which "fails".
There are also lot of screenshots, I did not figure out which is "expected look" and which
"actual look".
Please next time rename your screenshot files ("1_expected.png", "1_actual.png",
"2_expected.png" ...), I have problems distinguish which is "5th".
They're sent in a chronological order internationaly
Next time however i will name my screenshots properly
here's the swf itself (with the unedited shape) and my svg file
3160 original.svg (14 KiB)
cec2dr.swf (6,558 KiB)damn wrong file so sorry
3111.svg (104 KiB)This is fixed in nightly 3214.
The problem was in gradients stop element offset attribute, where FFDec did not correctly
handle empty value (missing the attribute should be equal to 0).
State: new→upgraded
Thanks for the quick response!
Not a guy with technical knowledge regarding flash but how did these empty values appear?
Or is that way too off topic and should be stopped being discussed here?
Well its in SVG attributes:
Each gradient has <stop> tags which define colours of the gradient and their position on
scale 0 to 1.
The position is marked with attribute "offset". It has default value of "0" if it is not
set - and this FFDe did not handle correctly.
The fragment from your SVG file:
<radialGradient
id="paint1_radial_2218_485-9"
cx="0"
cy="0"
r="1"
gradientUnits="userSpaceOnUse"
gradientTransform="matrix(52.9751,0,0,16.3731,75.814464,60.753157)">
<stop
stop-color="#E9B819"
id="stop423-1" /> <!-- does not have offset attribute - should be assumed 0 = at
the start -->
<stop
offset="1"
stop-color="#E31026"
id="stop425-9" /> <!-- has offset 1 = the color is at the end -->
</radialGradient>
FFDec just thrown an exception with missing offset attribute and produced empty fill.
It's fixed now.
