## Tools / How-to
Use your favorite picture editor to adjust size, or use "convert" from [ImageMagick](imagemagick.org), which is a powerful image manipulation tool. It is open source and available for all common operating systems.
> [!INFO]
> From version 7 of [ImageMagick](imagemagick.org) you will get a warning when running with `convert` or `magick convert` saying that the command is depricated and you should now use `magick` only
> `WARNING: The convert command is deprecated in IMv7, use "magick" instead of "convert" or "magick convert"`
### To just scale the picture down, use:
```
$ magick source.jpg -resize 240x304 destination.bmp
$ convert source.jpg -resize 240x304 destination.bmp
```
### If you see and don't want a frame left and right, you can adjust the convert with:
```
$ magick source.jpg -resize 240x304 -gravity center -extent 240x304 destination.bmp
$ convert source.jpg -resize 240x304 -gravity center -extent 240x304 destination.bmp
```
### To choose the filling color when resizing/extending the image, add '-background color' after 'source.jpg':
```
$ magick source.jpg -background "#000000" -resize 240x304 -gravity center -extent 240x304 destination.bmp
$ convert source.jpg -background "#000000" -resize 240x304 -gravity center -extent 240x304 destination.bmp
```
or
```
$ magick source.jpg -background black -resize 240x304 -gravity center -extent 240x304 destination.bmp
$ convert source.jpg -background black -resize 240x304 -gravity center -extent 240x304 destination.bmp
```
The list of predefined colors can be obtained with ```convert -list color```

If it is saying '8-bit', you're good. It's the number of bits by color components. For sRGB, 8+8+8 = 24-bit
_If you have save the image via a different program and it looks right when using the identify command above, try to convert anyway with magick._

## Limitations
- image have to be a 24 bits bitmap
- width have to be exactly 240 pixels wide
- height have to be in the [ 1 , 304 ] range. Any additional lines will be cut
