Is it possible to edit image gradients?

android272 · Postby **android272** » Fri Aug 29, 2014 4:15 am

I am not asking how to edit the gradients color, stops, opacity, or position on the image. I have many objects on my canvas with the same exact gradient and it seems as though every time I make a copy of an object inkscape duplicates my gradient. I have SOOOOOOOOOOOOOOOOOO many duplicates of the exact same gradient its not funny. I have not changed the color of the gradient what so ever since I created it and started making my icons that gradient.

should I just clear my icons gradient by changing it to a solid flat color, then copy it to a new image and recreate the gradients? This would suck since I have so many. I have around like 500 the last time I counted.

Yes. See this thread: Duplicate object with gradient: Edit 1 gradient = edit both?
There are some bugs. But also a workaround.
I had the same problem and did some investigation lower down in the thread.

I'd probably use a text editor to change all the references to the "original" gradient. (I'm on Windoze, so I use "Textpad".)

Each object will still have their own gradient id, but all can point to the original via xlink:href...

Code: Select all

        <linearGradient
       inkscape:collect="always"
       xlink:href="#linearGradient3755"
       id="linearGradient3799"
       gradientUnits="userSpaceOnUse"
       x1="31.4285717"
       y1="105.2193222"
       x2="137.1428528"
       y2="105.2193222" />

In the above, the "linearGradient3799" is the id for the third object's gradient, but it is referencing "#linearGradient3755" (the original object's gradient settings for stop info). That xlink:href value is the item to replace.

It will require find/replace in all the defs, but might be faster than using the pallette GUI.

After revision, vacum-defs would remove unused gradients.

Thanks this is great. Why does Inkscape do this? I mean I understand having many gradients with slight changes but if there are two gradients that are exactly the same should not Inkscape use the original gradient already in use?

As noted in the topic linked above, users get the choice:
Ctrl-D (duplicate) of an object does indeed use the very same gradient.
Copy/paste generates a new gradient id with the same attributes, that the user can modify without disrupting the original.

The best choice depends on the user's needs.

In the example file I posted above, the first object is the original, the second is copy/paste, the third is a duplicate of the original. They all look the same, but only the first and third share the same gradient fill. The difference can be distinguished by looking in the fill/stroke panel, or in the Inkscape XML editor, or in a text/unix editor.
