title: Uploading Images
|
|
---
|
|
|
|
Here are a couple of general rules for contributing to Privacy Guides:
|
|
|
|
## Images
|
|
|
|
- We **prefer** SVG images, but if those do not exist we can use PNG images
|
|
|
|
Company logos have canvas size of:
|
|
|
|
- 128x128px
|
|
- 384x128px
|
|
|
|
## Optimization
|
|
|
|
### PNG
|
|
|
|
Use the [OptiPNG](https://sourceforge.net/projects/optipng/) to optimize the PNG image:
|
|
|
|
```bash
|
|
optipng -o7 file.png
|
|
```
|
|
|
|
### SVG
|
|
|
|
#### Inkscape
|
|
|
|
[Scour](https://github.com/scour-project/scour) all SVG images.
|
|
|
|
In Inkscape:
|
|
|
|
1. File Save As..
|
|
2. Set type to Optimized SVG (*.svg)
|
|
|
|
In the **Options** tab:
|
|
|
|
- **Number of significant digits for coordinates** > **5**
|
|
- [x] Turn on **Shorten color values**
|
|
- [x] Turn on **Convert CSS attributes to XML attributes**
|
|
- [x] Turn on **Collapse groups**
|
|
- [x] Turn on **Create groups for similar attributes**
|
|
- [ ] Turn off **Keep editor data**
|
|
- [ ] Turn off **Keep unreferenced definitions**
|
|
- [x] Turn on **Work around renderer bugs**
|
|
|
|
In the **SVG Output** tab under **Document options**:
|
|
|
|
- [ ] Turn off **Remove the XML declaration**
|
|
- [x] Turn on **Remove metadata**
|
|
- [x] Turn on **Remove comments**
|
|
- [x] Turn on **Embeded raster images**
|
|
- [x] Turn on **Enable viewboxing**
|
|
|
|
In the **SVG Output** under **Pretty-printing**:
|
|
|
|
- [ ] Turn off **Format output with line-breaks and indentation**
|
|
- **Indentation characters** > Select **Space**
|
|
- **Depth of indentation** > **1**
|
|
- [ ] Turn off **Strip the "xml:space" attribute from the root SVG element**
|
|
|
|
In the **IDs** tab:
|
|
|
|
- [x] Turn on **Remove unused IDs**
|
|
- [ ] Turn off **Shorten IDs**
|
|
- **Prefix shortened IDs with** > `leave blank`
|
|
- [x] Turn on **Preserve manually created IDs not ending with digits**
|
|
- **Preserve the following IDs** > `leave blank`
|
|
- **Preserve IDs starting with** > `leave blank`
|
|
|
|
#### CLI
|
|
|
|
The same can be achieved with the [Scour](https://github.com/scour-project/scour) command:
|
|
|
|
```bash
|
|
scour --set-precision=5 \
|
|
--create-groups \
|
|
--renderer-workaround \
|
|
--remove-descriptive-elements \
|
|
--enable-comment-stripping \
|
|
--enable-viewboxing \
|
|
--indent=space \
|
|
--nindent=1 \
|
|
--no-line-breaks \
|
|
--enable-id-stripping \
|
|
--protect-ids-noninkscape \
|
|
input.svg output.svg
|
|
```
