Some different sizes' logos are needed.

## the process of creation
|
|
|
|
No professional designers are here. Thus the following steps involve many programer styles. :-)
|
|
|
|
1. use excalidraw and export png and svg.
|
|
|
|
```bash
|
|
# results
|
|
logo.excalidraw
|
|
logo.png
|
|
logo.svg
|
|
```
|
|
|
|
2. manually edit the `logo.svg` and make background transparent.
|
|
|
|
```bash
|
|
# results
|
|
logo-transparent.svg
|
|
```
|
|
|
|
3. use python library [`svgutils`](https://github.com/btel/svg_utils) to make a strictly square figure. The [doc](https://svgutils.readthedocs.io/en/latest/tutorials/composing_multipanel_figures.html) is very useful.
|
|
|
|
```python
|
|
from svgutils.compose import *
|
|
def get_standard_300x300(file_name):
|
|
fig = Figure(300, 300,
|
|
Panel(
|
|
SVG(file_name),
|
|
).move(-3, 12),
|
|
)
|
|
return fig
|
|
|
|
get_standard_300x300('logo-transparent.svg').save('300x300.svg')
|
|
|
|
# def get_other_size_from_standard(file_name, px):
|
|
# fig = Figure(px, px,
|
|
# Panel(
|
|
# SVG(file_name).scale(px/300.0),
|
|
# ).move(-3*px/300.0, 12*px/300.0),
|
|
# )
|
|
# return fig
|
|
|
|
# get_other_size_from_standard('logo.svg',256).save('256x256.svg')
|
|
```
|
|
|
|
```bash
|
|
# results
|
|
300x300.svg
|
|
```
|
|
|
|
4. use `inkscape` command line to get different sizes' `.png` files.
|
|
|
|
```bash
|
|
inkscape 300x300.svg -o 300x300.png
|
|
|
|
inkscape 300x300.svg -o 50x50.png -w 50 -h 50
|
|
|
|
inkscape 300x300.svg -o 64x64.png -w 64 -h 64
|
|
inkscape 300x300.svg -o 256x256.png -w 256 -h 256
|
|
```
|
|
|
|
```bash
|
|
# results
|
|
50x50.png
|
|
64x64.png
|
|
256x256.png
|
|
```
