Yaru: Render Script

[rares45]

To render the custom icon

(What you were trying to do)
I was trying to render a costume icon made with the blank template.
I have the latest version of Inkscape and OptiPng.

Actual Behavior

(What happened instead)
There was no output. No text output and no final image output.

Steps to Reproduce the Problem

1. Try to render a costume icon using the render service

Hi @rares45, thanks for reporting this issue. Could you copy the exact command you used?

[rares45]

Hi @clobrano . I tried these commands:
./render-bitmaps.py actions/system-hibernate.svg
and
./render-bitmaps.py system-hibernate.svg

the folder tree is like this:

.
├── actions
│ └── system-hibernate.svg
├── render-bitmaps.py
└── system-hibernate.svg

[clobrano]

render-bitmaps.py uses the name of the file without the extension, have you tried that already?
If it works, we better update the doc to make it clearer

[rares45]

@clobrano I just tried it, but there is another problem. Output:

Could it be because I changed the location of Inkscape to /snap/bin/inkscape?

Hi @rares45

I don't think that you can use text inside an SVG, so before you render it, you may have to make it into a path.

[rares45]

@madsrh The only text is in the baseplate and it is hidden. I did try converting text to path, but now I get:

Traceback (most recent call last):

[clobrano]

Just to rule some problems out, if you run the script on the repository without any change, does it work?

[rares45]

@clobrano The only change I made is changing "/usr/bin/inkscape" to "/snap/bin/inkscape", but it still doesn't work on the repository. The output is similar to the output in this comment.

[clobrano]

Sorry for the delay, but I couldn't find the time to look at this from my pc :sad:

[ubuntujaggers]

Hi @rares45,

Don't convert the text in the baseplate to an object because the script needs to be able to read the category and icon name as text :)

To be clear, do you get these error messages if you run the unaltered script on an unaltered (existing) icon using the following command:

cd ~/yaru/icons/src/fullcolor && python render-bitmaps.py application-x-lmms-project

??

Hi,
The error occurs even when trying to render script without any change to repository. I tried running script first with Snap's Inkscape and then with Flatpak's Inkscape and got the same ouptut as @rares45:

Traceback (most recent call last):
File "render-bitmaps.py", line 219, in
main(args, SRC)
File "render-bitmaps.py", line 203, in main

File "render-bitmaps.py", line 144, in endElement
assert self.icon_name
AssertionError

However, I do not get this issue and the script renders when I use the Ubuntu-repository Inkscape
Does it have something to do with the latest version of Inkscape ?

Versions tried on:
Snap Version: v1.0-6e3e5246a0-2020-05-07 (latest/stable)
Flatpak Version: v1.0 -stable (org.inkscape.Inkscape)
Ubuntu Version: v0.92.5 (2060ec1f9f, 2020-04-08)

Thanks!

[clobrano]

However, I do not get this issue and the script renders when I use the Ubuntu-repository Inkscape

This considered, I think it has something to do with the version indeed. We must investigate to see if it's a regression or not. If the latter, we shall fix either the svgs or the script

[clobrano]

Hi again,

I had a look at the script and found the following:

1. the script needs a lot or rework, but it seems to work fine with inkscape, from the repository, when provided with the proper input, as example:

   icons/src/fullcolor $ ./render-bitmaps.py window-close

   that is, the script needs the name of the file without the full path and without the .svg extension

2. snap version of inkscape does not work for me, because of missing permission to access hidden directories under $HOME (see https://askubuntu.com/questions/1049587/permissions-for-home-config-for-snap)

[ubuntujaggers]

Likewise, when I got my new laptop I originally installed the snap and realised that the script didn't work. Installed non-snap inkscape from terminal and it did.

[Muqtxdir]

Leaving aside the snap-missing permissions,

I installed Inkscape-latest from their ppa (https://inkscape.org/release/inkscape-1.0/gnulinux/ubuntu/ppa/dl/) and I have the same trouble with rendering as with Inkscape-snap

[clobrano]

Could you post the output, including the command you issued?

[Muqtxdir]

command and output in screenshot:

Inkscape version: Inkscape 1.0 (1.0+r73+1)

command : ./render-bitmaps.py extensions

[clobrano]

The FontConfig issue seems similar to this bug : "that's likely to happen only when you are running something with older library with new config". Maybe a packaging problem in the snap?

The other one is a problem. Basically inkscape 1.0 does not work anymore with the command that was working until 0.96. We shall find a substitute command :cry:

hi,

the adwaita-icon theme also had the same problem with the release of inkscape-v1
the rendering script was fixed by modifiing these:

Adwaita's render script: https://gitlab.gnome.org/GNOME/adwaita-icon-theme/-/blob/master/render-icon-theme.py

thanks!

[clobrano]

Thanks @Muqtxdir, I'll check how to integrate this

[fouzan14]

On Ubuntu 20.10, I can say this problem exists !
Will this be fixed before Ubuntu-20.10 releases?

[clobrano]

Since this is a build script, we're not bounded by the releases, which means that as soon as it is fixed it will be available to anyone.

[leinardi]

I'm experiencing the same issue, is there any workaround?

EDIT
Sorry for the noise, I was not using the latest version of the script. The version of 23 Oct 2020 works fine :+1: .

[clobrano]

Hey @leinardi, thank you for the feedback, I forgot to close the ticket :)
