inkscape-applytransforms's Introduction

inkscape-applytransforms

An Inkscape extension which recursively applies transformations to shapes.

Note that performing this operation on certain shapes (stars, lpes, ...) will convert them to paths, and clones are affected in strange ways due to clone transforms behave.

update 2020-7-27 - updated to work with Inkscape 1.0+. Use legacy branch inkscape-pre1.0-compat for prior version of Inkscape.

update 2016-1-5 - now only affects selected shapes when there is an active selection.

Installation

Download applytransform.inx and applytransform.py, then copy them to the Inkscape installation folder subdirectory share\inkscape\extensions.

On Windows this may be C:\Program Files\Inkscape\share\inkscape\extensions (or %appdata%\inkscape\extensions if you don't want to install globally)
On Ubuntu, this may be /usr/share/inkscape/extensions/ or (~/.config/inkscape/extensions if you don't want to install globally)
On macOS, this may be ~/Library/Application Support/org.inkscape.Inkscape/config/inkscape/extensions
Generally, you should be able to go to the Inkscape Preferences, select System, and see the path for User extensions

If the downloaded files have .txt suffixes added by GitHub, be sure to remove them. Restart Inkscape if it's running.

Arch Linux

This package is also available via the AUR.

pacaur -S inkscape-applytransforms-git

Usage

Activate the extension from the main menu:

Extensions | Modify Path | Apply Transform

or use it from the command line. The id of the extension is automatically available as a verb:

inkscape -g --verb com.klowner.filter.apply_transform test.svg

Command --verb

The command-line option --verb is deprecated

Extension needs a license (publish to inkscape.org)

Hi Klowner,

could you add a license to the extension? It's a useful tool for many people, but it's currently not 'safe to use'. I would suggest 'GPLv2 or higher', for it to be compatible with Inkscape's licensing.

ImportError: No module named paths

everytime I try to run the extension independently of the number and type of objects selected, I get this message

Traceback (most recent call last):
  File "applytransform.py", line 9, in <module>
    from inkex.paths import CubicSuperPath, Path
ImportError: No module named paths

It does not work for polygons.

Steps to reproduce:

Select polygon containing translate transform,
Start Apply Transforms.

Expected result:

Polygon position is the same as before applying transforms,
Polygon does not contain transforms now.

Actual result:

Transform is removed,
Points contain old values,
Polygon is moved in result.

Environment:
Windows 10, Inkscape 0.92.1.

ApplyTransform: stroke-width changes without scale

The stroke width seems to change also if there is no scale.
I uploaded a svg, you can execute the apply transform several times. The stroke width grows every time.

TestApplyTransform.zip

Thank you.

Does not work for me at all

This extension does not work for me. It simply removes the transform attribute from the <polyline> element, but does not apply the transform to the data in the points attribute.

str() casting in Path

Hi,

i created a new inkscape extension which is calling ApplyTransform class externally to do some cool stuff. This works fine for most things but it seems there is some small hidden error which was was able to fix by simply adding a str() cast. i am asking if you could add this to that repo. the explanation:

/home/tomate/.local/lib/python3.8/site-packages/shiboken2/files.dir/shibokensupport/__feature__.py:142: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses
  return original_import(name, *args, **kwargs)

the external call i did was

...
applyTransformAvailable = False

...

        # at first we apply external extension
        try:
            sys.path.append("..") # add parent directory to path to allow importing applytransform (vpype extension is encapsulated in sub directory)
            import applytransform
            applyTransformAvailable = True
        except Exception as e:
            # inkex.utils.debug(e)
            inkex.utils.debug("Calling 'Apply Transformations' extension failed. Maybe the extension is not installed. You can download it from official InkScape Gallery. Skipping this step")

...

        if self.options.apply_transformations and applyTransformAvailable:
            for shape in self.svg.selection:
                applytransform.ApplyTransform().recursiveFuseTransform(shape)

i changed the line 75 from

            node.set('d', Path(CubicSuperPath(p).to_path())

            node.set('d', str(Path(CubicSuperPath(p).to_path()))

now this works perfectly

Fails from command line 100% of the time

I'm running
inkscape --actions="com.klowner.filter.apply-transform;export-do" file.svg

the svg looks like

Is there any way to get a verb for this so it can be run from the CLI?

I would like to apply this as part of a build script. I like having a source SVG with all the original transforms for easy editing, but optimizing the output requires flattening all these things. I'd like to add this as a verb to my scripts. Is there a way to define a new verb in an extension?

Applying transform on a clipPath

When a clipPath is used, the transform is not applied to it.

This might be tricky since different elements might use a single clip path at the same time so it might need to be cloned.

Example:

Same with Mask:

can't find 'main' module in 'C:\\Program Files\\Inkscape\\bin'

Getting the following error when running the plugin:
C:\Program Files\Inkscape\bin\pythonw.exe: can't find 'main' module in 'C:\Program Files\Inkscape\bin'

Inkscape 1.2.2 (732a01da63, 2022-12-09)

`TypeError: uutounit() missing 1 required positional argument: 'to_unit'`

On inkscape 1.0.2 (e86c8708, 2021-01-15), I run this extension on a file and get

Traceback (most recent call last):
  File "applytransform.py", line 159, in <module>

related: #43

From https://gitlab.com/inkscape/extensions/-/blob/3796f912f666a0981917839c77eb94fdd6fc6a94/inkex/elements/_base.py#L453 it doesn't seem that to_unit is a required argument. But for me, that function is defined in /Applications/Inkscape.app/Contents/Resources/share/inkscape/extensions/inkex/elements/_svg.py as

    def uutounit(self, value, to_unit):
        """Convert from the document's units to the given unit"""
        return convert_unit(render_unit(value, self.unit), to_unit)

So this must have changed in a more recent Inkscape release. Indeed, at this commit:

https://gitlab.com/inkscape/extensions/-/commit/e15529f3ae9c1ee951ca4a60fd7b9f24be16126c

It should just be passed the "px" argument, then.

Update Windows path for installation in README

I recently downloaded Inkscape 1.0.2 for Windows. I can confirm that the recommended path C:\Program Files\Inkscape\share\extensions does not work. The path is C:\Program Files\Inkscape\share\inkscape\extensions.

Update for Inkscape 1.0

There are some deprecated functions and dependencies.

After removing the deprecated dependencies from applytransforms.inx (as per http://wiki.inkscape.org/wiki/index.php/Updating_your_Extension_for_1.0) so that the extension will run, I get the following errors. The first few are easy enough to fix, but I haven't picked through the rest just yet!

deprecated multiplication operator

When trying to apply transform i get a deprecated warning:

DeprecationWarning: inkex.deprecated.main.transform_mul -> Use @ operator instead
  transf = Transform(transf) * Transform(node.get("transform", None))

ellipse in group

it didn't get applied to an ellipse in a group, but did get applied to paths in the group. sadly i have lost the file already so i can't provide a testcase.

Any advice? Thanks!

I recive a error in new version of inskape

What to change?

Please update the files on the Inkscape.org repository.

The version on Inkscape.org is the old one that doesn't work with the new Inkscape.
Thanks

Does not remove all scale transformations

I flipped some objects with Edit->Flip Horizonal/Vertical (or hitting v or h)

After running the plugin, the source is still left with: transform="scale(-1,1)"

Maybe this is the desired behaviour, it wasn't for me :)

Thanks for an otherwise very useful plugin!

Issue in the last commit made at Oct 19, 2019

Good day!

The last commit at Oct 19, 2019 has introduced a new issue. Please look at the line 55 (as it seems) of the script:
stroke_width *= math.sqrt(transf[0][0] * transf[1][1])

This code will cause a domain error while scaling stroke width in case the figure being transformed has been previously flipped (mirrored) around one of the axises.

I propose to correct the problem by getting absolute value of the multiplication:
stroke_width *= math.sqrt(abs(transf[0][0] * transf[1][1]))

Best regards,
Alexey

I have 1 untransformed path and one that is transformed but because the stroke width doesnt change, the lines are noticeably thicker. Wondering if this is by design, or i am doing something wrong with the plugin or if this is actually an issue.

I also wanted to ask if it is also by design that any labels on the path get removed after a transform, it is slightly annoying when i have labelled everything then go to transform and all the labels are replaced with auto generated names.

Failure to transform some paths

For some SVGs the extension fails with the following error:

Cannot do a translate on a rectangle

Currently cannot perform even a simple translate transformation on a rect element.

Example:
<rect width="1" height="1" x="2" y="2" id="rect1" transform="translate(2, 2)" />

Expected result:
<rect width="1" height="1" x="4" y="4" id="rect1" />

Thanks for your extension! Unfortunately it doesn't work for me:

$ python --version

Maybe it's a bug in ubuntu / inkscape?

Does not seem to work for layer transform

Take a SVG file and delete some path in it. Then go to "Document properties" and click "Adjust page to drawing or selection". You'll get a transform on the layer itself that's not removed by this extension.

SyntaxError: invalid syntax

Extension does not work with my last Inkscape version. The following error is displayed :

`circle` elements don't get transformed

Here's the original SVG (with .txt extension added so github accepts it...):
plate.svg.txt

The original SVG rendered as PNG:

SVG with "Apply Transform" run, rendered as PNG:

And finally, the transformed SVG:
plate-transformed.svg.txt

It looks like the outline had the transformation applied, but the circles did not.

Apply - to what?

I thought this addon will help me to flatten transformations but i was wrong. It just exchanges one or few transformations add to object into one matrix transformation. I have two apps which i need to import created SVG and they totally don't understand matrix transformation thing. Really don't understand what this addon was for from the very start.

Bring to Inkscape Extensions Core

This extension would work well as a core extension installed by default for all Inkscape users.

If you'd like to bring this extension to https://gitlab.com/inkscape/extensions/ with a merge request (it'll need to be upgraded to 1.0 and have a comparison test written) but would be a good addition.

DeprecationWarning: inkex.deprecated.main.transform_mul

I try the extension on Inkscape 1.2.1, I've got the following error.

applytransform.py:60: DeprecationWarning: inkex.deprecated.main.transform_mul -> Use @ operator instead
  transf = Transform(transf) * Transform(node.get("transform", None))

I found the line in the Python script, but I'm not sure how to update the code.

transformed path elements no longer filling

latest version of extension (as of 2019-12-22).
Inkscape 0.92.4 - Windows 10 Pro

stripped my svg file down to 1 grouped element, goal is to create a set of svg symbols to make up an Inkscape symbol library. So I need to eliminate the transform attributes per the Inkscape share/extensions/README. This extension does that quite well. I tried this both by un-grouping the set of path, text objects as well as using the source as is.
But weirdly, after running the extension, several of the path elements no longer render as previously. They are there - if I use the Object-> Objects tool, select the elements, they are present with the expected attributes, including the same style:fill RGB value as previously. If I use the 'Edit path by nodes' tool, the vertices are rendered, I can then use the 'show path outline' tool to show the polygon's edges. But no fill rendering as before. 1 item I noticed was the replacement of the z closepath instruction with trailing relative moves to the origin. I replaced these with the z instruction to see if it helped (ensuring the polygon was closed so a fill can be handled). No difference in the rendering. Nor did selecting either/both of the affected 2 path elements, then raising them to the 'top' of the rendering stack make any difference (ie. not occluded by some other object, that I can tell).

an xxdiff of the 2 attached files doesn't point out anything obvious to me. Nothing in the defs element was affected(?) by the apply transform extension.
But I'm not an SVG nor Inkscape expert :-(
Many thanks for writing this extension.

Negative values

Hi, have a look at the attached image. When applying tranforms, I still get negative values:

Here is the preview in another app:

But image is still fine in InkScape. Did I miss something or is it a bug?

apply transformation to linearGradient

After transformation is applied start and end point of linearGradient don't change. Thus SVGs look different.

It would be nice to have start and end point of linear gradients converted according to transformation.

scaleStrokeWidth calculation not completely correct

As it currently stands, a line tilted at 45 degrees will get a different width than a vertical or horizontal line. In order to properly handle rotations, line 49 should actually be
stroke_width *= math.sqrt(abs(transf.a * transf.d - transf.b * transf.c))
This is because the width of something is better defined in terms of the transform's determinant. The above version is rotation-invariant.

Thanks for making this—I incorporated a version into my own extensions.

return [kind(val) for val in string.replace(',', ' ').replace('-', ' -').replace('e ', 'e').split()] ValueError: could not convert string to float

Steps to reproduce:
Open SVG in the Inkscape 1.0.2

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 459.75 385.83">
   <g id="test">
    <path class="cls-1"
