shriinivas / inkscapestrokefont Goto Github PK

Hi,

I've added some additional fonts to the strokefontdata folder (added the EMS fonts) and then selected Sync Fonts. Nothing seems to happen. When I look the drop downs, nothing has updated.

I thought I read that an XML file is created, but I don't see one.

I've tried just modifying one of the names of the existing fonts to see if that works - not updated.
I've coped the font folder to here:
...AppData\Roaming\inkscape\extensions\inkscapestrokefont-master\strokefontdata

and
...\AppData\Roaming\inkscape\extensions

Thanks

Hi, Great extension, but I'm getting this error:
No font data; please select a font and ensure that the list is synchronized

You can see from the pic that I have select my new custom font, but the extension doesn't seem to recognize it.

Windell Oskay commented on my blogpost that there should be no issue with Hershey Text to read special characters and asked me to report it as an issue and provide an example file where Hershey Text fail to read the SVG-font. It seems that the svg-font files I generate with the Custom Stroke Font have incorrect coding (not UTF-8 for real). See more in this issue and what Windell Oskay found. I guess the same is the case when FontForge fail to read the svg-font files from Custom Stroke Font. I can live with my workaround in the blogpost mentioned above, but maybe there is something that could be fixed from within the Custom Stroke Font extension?

While trying to design a new font, I can't change the XML ID to ":" because Inkscape 1.2 considers this an Invalid ID. (Oddly, If I edit an existing font, it seems to have no problem.).

How is this supposed to work? This seems to be true for other special characters as well.

I was converting a ttf fot to svg using FontForge and when trying to edit this using the Custom Stroke Font - Edit Font it failed and I got nothing. It turned out that there was quite a few glyphs in the svg from FontForge missing the horiz-adv-x attribute. I guess this is a bug in while FontForge generate svg-font (the left/right bearings of those glyphs look fine when inspecting them in FontForge). Anyway - this problem was fixed by changing line 114 of stroke_font_manager.py

From
rOffset = float(e.getAttribute(xROff))

To
if e.getAttribute(xROff) == "":
rOffset = 0
else:
rOffset = float(e.getAttribute(xROff))

Ideally there should be a warning in the end that some (ideally which) glyphs had missing horiz-adv-x and that this is set to 0, or it could be set to the width of the bounding box to have something that might work - not as strange and obviously wrong as 0.

At least this made it possible to continue editing the font. So I'm happy with this solution.

First of all, thank you for your developments. Maybe this can help you improve it ! Best regards.

• I installed the external extension "inkscapestrokefont" from here
• open Inkscape
• menu Extension / "Custom Stroke Font" available
• errors are appearing for each submenu
• dialog appears and seems to work fine
  - drop down menus OK
  - entering data OK
  - selecting options OK
• then click on button apply
  => dialog appears with error message below

SUB MENU 1

• Select in the submenu "Create Font Design Template"
• Apply (default values)
• Inkscape returns message:
  File "stroke_font_templ.py", line 97 try: self.startGlyph = eval("u'\u" + sg + "'") ^ SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \uXXXX escape
• Nothing happens next.

SUB MENU 2

• Select in the submenu "Edit Stroke Font"
• Apply (default values)
• Inkscape returns message:
  Traceback (most recent call last): File "edit_stroke_font.py", line 31, in <module> from stroke_font_common import CommonDefs, InkscapeCharDataFactory, createTempl File "/Applications/Inkscape.app/Contents/Resources/share/inkscape/extensions/stroke_font_common.py", line 84 print getXMLItemsStr(sectMarkerLine, sectMarker, fontNames), ^ SyntaxError: invalid syntax

SUB MENU 3

• Select in the submenu "Generate Font Data"
• Apply (default values)
• Inkscape returns message:

Traceback (most recent call last): File "gen_stroke_font_data.py", line 37, in <module> from stroke_font_common import InkscapeCharData, CommonDefs, \ File "/Applications/Inkscape.app/Contents/Resources/share/inkscape/extensions/stroke_font_common.py", line 84 print getXMLItemsStr(sectMarkerLine, sectMarker, fontNames), ^ SyntaxError: invalid syntax

I guess the other menus can generate similar issues, I did not try them.

Inkscape Version and Operating System:

Inkscape Version: 1.0beta2 (2b71d25, 2019-12-03)
Operating System: MacOS X Catalina
Operating System version: 10.15.4

I see the Custom Stroke Font menu and sub-menu but they are all grayed out.

With Inkscape v1.1 and v1.0.2 in Windows at least the Edit stroke font and Generate font data did not work (did nothing, and no error message). It turns out that this currently have to be fixed by the workaround described in
this issue #2187
(i.e. removing two lines of Inkscape \lib\python3.8\site-packages\numpy\init.py)

Thought you would like to know. Sounds like this will be fixed in the future releases of Inkscape as it applies to other extensions too.
