This commit: peterennis@7eab458

Is it possible to create a new layer? If it is, I cannot figure out how to do so - at least not correctly.

The main wiki page states that "For example, the document as a whole can be read and modified via self.svg". However, when I try to access self.svg in a script (e.g. layer = self.svg.add(Group('New Layer Name', is_layer=True))), I get an exception: NameError: name 'self' is not defined

I had limited success with this:

layer = inkex.Layer.new('New Layer Name')
inkex_object(layer)

However, I can't then figure out how to add items to it. Any objects I create appear on the default layer, and I can't find a working way to move them to the new layer. Also, the new layer appears as a child of a new, unnamed layer - not at the top level of layers.

Similarly to the rotate method : rotate(angle, anchor, first) , the scale(factor, first) method should also accept an anchor.

Why:

Because if the scale is applied on the object multiple times, the object is moving and that's not necessarily the desired behaviour. So basically, scale should add anchor argument so the user could specify the center of the object to be used.

Steps to reproduce the reported bahaviour:

• Draw an object, e.g. a rectangle and select it.
• Run the following code:

objs = svg_root.selection

for obj in objs:
   obj = inkex_object(obj)
   obj.scale(1.2)

When you keep pressing "Apply" button, the objects get scaled but move also.

I am using the functions text and more_text to insert some text. I need to insert a newline as follows:

text('Hello, ', (width/2, height/2), font_size='24pt', text_anchor='middle')
more_text('Inkscape', font_weight='bold', fill='#800000')
more_text('!!!')
more_text('\n')
more_text('A new line')

But when I run that code, I get the following error:

<string> 4

Simple Inkscape Scripting offers a lot of amazing possibilities for procedural generation.

Right now however, it can be a bit cumbersome to always write Python code inside SIS's dialogue box (e.g. no syntax highlighting, potential indentation errors, etc) or having to click 'Apply' each time you write code outside of Inkscape.

At the moment, Inkscape already supports command line arguments. Is there a way that you can then generate and export/SVGs with Simple Inkscape Scripting through calls to Inkscape via the command line?

Loading the example with my inkscape settings does not show a result
without zoom.

Add viewbox gives this result.

Should this be made consistent for demos?

Hello Scott

Sorry to bother you again ... last question, I swear
What about effects, I mean inkscape:path-effect?
for example construct_grid effect?

I am selecting multiple paths in the canvas and when I apply the rotation transform for each selection it seems that the objects are not rotating about their own rotation center.

objs = svg_root.selection
for obj in objs:
   obj.transform.add_rotation(30)

How can specify that each obj should its "own" rotation center for the rotation transform?

Many thanks

I look forward to see some examples that demonstrate the power of scripting to create some animations, such as SVG animations, or exporting shapes as png and using an external tool such as ImageMagick to create gif/video files

Thanks

Dear Scott!

Thak you for crating and letting us use this extension!
If you could add the feature mentioned in the title, transformations especialy rotation would be much simpler!
Thak you in advance!

As per title
Is it possible to use filters in python code?

btw Excellent tool, thanks!!!!

Fantastic extension. Really enjoying it and well documented. I'm trying to get the size of and image and the center of an image. The bounding _box feature is returning only the top left anchor point. Similar to text. Same when using clone. Is there another way to get image size info? I'm want to add borders around a mix of photos in a folder.

I get this error message: (extensions folder is on chmod 755)

Traceback (most recent call last):
File "simple_inkscape_scripting.py", line 24, in
import PIL.Image
ModuleNotFoundError: No module named 'PIL'

I read the code but there are no instructions on how to actually
display the animation.
How does it work?

I saw the readme has links to docs so I will peruse that to
see what I can find and report back.

Greetings
I started today to play with the examples provided in this repository, and to be honest it's mind blowing ;)
I am reading the Wiki page to learn more about the available options/shapes, etc.

I wonder how can I access the Canvas size from within the extension?

I have tried:

canvas_width  = self.unittouu(svg.get('width'))
canvas_height = self.unittouu(svg.attrib['height'])

But it doesn't work.

• Is there a proper way to get these info inside the extension?
• How can I access the selected objects on the canvas?

Have a nice day

This issue is tested on Microsoft Win10,
with the screen resolution of 1920x1080,
with Inkscape 1.1 and many 1.2-devs.

The dialog box of "Simple Inkscape Scripting" cannot be resized,
so I cannot see the [Apply] button,
please check.

Thank you!

Hello,
Sorry, if this doesn't deserve its own issue.

The new rotate and scale that accept anchor points work perfectly for different objects such as rectangles, circles, etc.

However, this doesn't seem to work for Polygons, Stars, text, or spirals.

How to reproduce:

• Create a star (or an polygon, or a text or a spiral) and select it.
• Run the code:

objs = svg_root.selection

for obj in objs:
   obj = inkex_object(obj)
   obj.scale(1.2, around='center')
   #obj.rotate(angle, around='center')

Fill is carried over from loaded script into the textbox code.

Following your directions on how to use animation I created an update of the
web code with svg and gif.

Commit here: peterennis@0528fa6

1. I used ScreenToGif to get a screen recording
2. Page setup was added otherwise the animation would run from corner to corner in full screen
3. Added the clear.py code to help with testing

How can I use parameters that will make a viewbox the size of the window
and mitigate screen resize issues?

captured in file:

simp_ink_err.pdf

Steps:

1. Load and run 100 shapes sample (Inkscape 1.1.1)
2. Delete code and paste another example
3. Run new code

Error.

Needs a button to clear the existing script ???

Using this code from the wiki:

Test case here: peterennis@9dc1d5a

I get a green box, no animation, and no feedback.

The other examples in the list are working. I commented them out
to show this issue. The intent is to run all the examples as one test
with adjusted begin times. I tried also with repeat count = 2

How would I go about debugging? Using print("here") does not provide
any useful data other than to show the interpreter has passed the
problem line.

When using set method to change the style of an object, e.g:

objs = svg_root.selection
for obj in objs:
   obj.set('width', 50) # <<<<<<< the value is numeric

When you run that, nothing changes. Instead the user need to explicitly to convert the value to a string, i.e.:

obj.set("width", str(50))

SimpIncScr should at least raise an error explictly when the value is numeric or convert it automatically.

The example script crashes.

It looks for python 3.9

I am running 3.10.1 on Windows 11

I am trying the recent API of SimpInkScr using Inkscape 1.2-dev:

objs = svg_root.selection

for obj in objs:
   obj = inkex_object(obj)
   obj.rotate(50, 'center')

The document is empty but I have selected the Layer 1 from "Object > Layer and objects" as shown below

But I am getting this confusing error message (I believe this could happen, if the layer is accidently selected intead of an object).

Is there an easy solution to get a meaninful error message to inform the user that the selection is a layer so it couldn't be transformed?

I found that Robert Penner's easing functions are a standard for simple animation.
A GPL v3 port to Python is found here:

https://github.com/semitable/easing-functions

Is it possible to use in SIS? I do not know enough Python yet to
deal with the integration.

e.g., I would like to extend your rectangle animation so that the boxes
bounce back and forth using one of these easing functions.

A more general question is how to integrate other Python libraries?

Hi,
When I run the extension, the main window looks like this:

As you can see, the window is small and more particularly, the code area is very small and one needs every time he/she opens this extension to resize the window. So every time I open the extension I need to resize the window to something like this:

I hope this gets fixed.

Thank you

Hi,

It would be nice if we could add SVG files into the repo, showing how each example script's render would look like. Then we could also link the preview to the example list.

Perhaps I could try and raise a pull request. Any thoughts?

Hi,
Thank you very much for this amazing extension.
I have some notes about the code text box: it doesn't use a verbatim text (monospace font) which makes code reading much harder. Also, there is no syntax coloring. For an example please take a look at this extension: https://github.com/textext/textext

Thank you very much

Is it possible within the script to create a new document or at least to clear canvas?
What I would like to achieve is to create similar Seasons greeting cards with unique name of recipient.

This code:

r01 = rect((0, 0), (32, 0), stroke='#2b1100', fill='#ff0000', font_variation_settings='normal', opacity=1, vector_effect='none', fill_opacity=1, fill_rule='evenodd', stroke_width=1, stroke_linecap='butt', stroke_linejoin='miter', stroke_miterlimit=4, stroke_dasharray='none', stroke_dashoffset=0, stroke_opacity=1, _inkscape_stroke='none', stop_color='#000000', stop_opacity=1)
r1 = rect((0, 0), (32, 1024), stroke='#2b1100', fill='#ff0000', font_variation_settings='normal', opacity=1, vector_effect='none', fill_opacity=1, fill_rule='evenodd', stroke_width=1, stroke_linecap='butt', stroke_linejoin='miter', stroke_miterlimit=4, stroke_dasharray='none', stroke_dashoffset=0, stroke_opacity=1, _inkscape_stroke='none', stop_color='#000000', stop_opacity=1)
r01.animate([r1], duration='2s')

r02 = rect((1024, 32), (1024, 0), stroke='#2b1100', fill='#ff0000', font_variation_settings='normal', opacity=1, vector_effect='none', fill_opacity=1, fill_rule='evenodd', stroke_width=1, stroke_linecap='butt', stroke_linejoin='miter', stroke_miterlimit=4, stroke_dasharray='none', stroke_dashoffset=0, stroke_opacity=1, _inkscape_stroke='none', stop_color='#000000', stop_opacity=1)
r2 = rect((0, 0), (1024, 32), stroke='#2b1100', fill='#ffff00', font_variation_settings='normal', opacity=1, vector_effect='none', fill_opacity=1, fill_rule='evenodd', stroke_width=1, stroke_linecap='butt', stroke_linejoin='miter', stroke_miterlimit=4, stroke_dasharray='none', stroke_dashoffset=0, stroke_opacity=1, _inkscape_stroke='none', stop_color='#000000', stop_opacity=1)
r02.animate([r2], duration='2s', begin_time='2s',)

This blinking:

This svg animation result:

1. Is the blinking expected? It gets longer as the animation increases.
2. Can it be reduced? Replaced with a progress bar? Just use ........ progress instead?
3. How can I do something similar to:
   r02 = rect((1024, 32), (1024, 0), f(get-the-settings())
   where get-the-settings returns the string of values?

I can create a path with a gap in it like so:

path_1 = path([Move(64, 64), Line(64, 128), Move(64, 196), Line(64, 256)])

If I reverse such a path, it no longer has a gap:

path_2 = path([Move(128, 64), Line(128, 128), Move(128, 196), Line(128, 256)])
path_2.reverse()

How can I reverse a path but preserve the gap?

Here is a screenshot of the result of those two snippets:

Thank you for a sweet API!

Thank for such great extension! I would like to automate the tedious work of creating guides. I usually create the same guides, at 10% of the size, plus 13% bottom margin and a final guide at 7% height.
Is there a function to create guides? I couldn't find in the documentation.

I have tried the example of connector avoidance: https://github.com/spakin/SimpInkScr/wiki#connector-avoidance

r1 = rect((100, 0), (150, 50), fill='#fff6d5')
r2 = rect((200, 400), (250, 450), fill='#fff6d5')
connector(r1, r2, ctype='orthogonal', curve=100)
circle((225, 225), 25, fill='red', conn_avoid=True)

It produces the shape without issues, but when I select the result and press Shift Ctrl G to ungroup it, Inkscape crashes

Thanks for such a lovely extension I'm having a great time with it!

I'm using it to generate electronic diagrams and would like to save the generated graphic to an SVG file.

I've been exploring with trying to get the svg structure out using the svg_root global variable but haven't been able to quite crack it.

Is this possible, or planned functionality in the future?

I'm building several simulated flight instruments and will be using .svg to represent the faces of dials in an aircraft. These include various markings distributed around an arc, as well as colored arcs of multiple lengths.

If I can do this with the current SimpInkScr, I'd like to learn how and add documentation to the .md file. If an additional function is needed, I'd like to learn to code it to be included in the SimpInkScr library, either locally, as part of your library.

        arc( outside_dia, inside_dia, start_angle, end_angle,color).

The second type of arc would place a rotated rectangular shape, similar to the markings on a clock face.

I want to write a second function that may be added directly to the library or given as an example:

       radial_marks(length, width, start_angle, end_angle, angle_incr, color)

The immediate goal is to produce items like this:

Hi,
Are there any plans to use unit tests and CI (github actions) for SimpInkScr?

This could make the developement and maintenance for several inkscape versions easier.

Thanks

Hello, sorry if this is a no-brainer, but I'm having trouble to get this extension running under Windows.

Environment:

• Windows 10 Pro 21H1, 64-Bit
• Inkscape v1.2 (dc2aedaf03, 2022-05-15) (Windows 64-Bit)

Steps to reproduce the bug:

1. Install Inkscape v1.2 (dc2aedaf03, 2022-05-15) for Windows via .exe: https://inkscape.org/release/1.2/windows/64-bit/.
2. Downloaded the lastest release (v3.1.0) of this extension.
3. Unzip the archive to get the folder simple_inkscape_scripting.
4. Copy the folder simple_inkscape_scripting to C:\Program Files\Inkscape\share\inkscape\extensions.
5. Start Inkscape via C:\Program Files\Inkscape\bin\inkscape.exe.
6. Open a new document via "New Document".
7. Start the extension via Menubar --> Extensions --> Render --> Simple Inkscape Scripting...
8. Insert a simple example script into the field "Python code":

   for i in range(10, 0, -1):
       ellipse((width/2, height/2), (i*30, i*20 + 10),
               fill='#0000%02x' % (255 - 255*i//10), stroke='white')

9. Click on "Apply".
10. A modal "'Simple Inkscape Scripting' working, please wait...' is opened.
11. Immediately after, an error modal is opened:

    Inkscape has received additional data from the script executed. The script did not return an error, but this may indicate the results will not be as expected.

    C:\Program Files\Inkscape\bin\pythonw.exe: can't find '__main__' module in 'C:\\Program Files\\Inkscape'
    

By the way, I have two entries "Simple Inkscape Scripting..." under "Extensions". I assume this is not intentional, but both commands behave exactly the same and there is no second simple_inkscape_scripting folder in my extensions folder.

Any help would be appreciated!

Description:

Exporting as "Simple Inkscape Scripting Script" is not documented

Steps to reproduce:

• Open inkscape
• Draw something
• File > Save and choose "Simple Inkscape Scripting Script" then click save
  

What happens:

• It saves a python file and user is confused

What do you expect:

• User expect some documentation about this functionality and know the limitations of it.

Additional Informations:

• Not specific to any platform

Hello,

I just discovered your extension via inklinea.
Many thanks for developing it !

I was wondering if it is planned to do the opposite workflow in SimpInkScr: trace/record the actions made in the GUI to tangle them in a python file for later modification and execution with different parameters for example ?

If I understand the current workflow, the way it is implemented is from the python script to the GUI.
Is this correct ?

Anyway, many thanks for this extension, IMHO it was missing in the Inkscape ecosystem in my opinion.
THANKS !

I tested default light and dark modes as well as enhanced light and dark modes.
The graphics shown are not good for dark mode. They would be better with a white
background. This appears to be a problem for all the graphics.

Is it possible to scatter objects along a path?
Example:

SIS is GPL v3+

This is fine, but it seems to me that using a simple script such as Clear.py (https://github.com/peterennis/SimpInkScr/blob/Synkypy/aepyx/002_Clear.py)
introduces copyleft with a sledgehammer.

I did some research on Python licensing here: https://docs.python.org/3/license.html

The relevant part is:

Terms and conditions for accessing or otherwise using Python
Python software and documentation are licensed under the PSF License Agreement.

Starting with Python 3.8.6, examples, recipes, and other code in the documentation are dual licensed under the PSF License Agreement and the Zero-Clause BSD license.

While learning Python and SIS it is not clear to me the licensing terms of the wiki examples.

I have some animations here: https://adaept.com/menu/home
and here: https://adaept.com/menu/logae
and here: https://adaept.com/menu/kute

I would like to port some of them to SIS SMIL but remain hesitant
due to the implicit GPL v3+ wiki license.

Please provide some clarification.
