A Series of Logos + the IM6 Scripts to Create Them

This is a series of “Powered by Devuan” logos for use in websites, or whatever you wish. There's not a lot, but an ImageMagick (IM6) script is provided for each option, and that means that you can spend the next 3 months customising the heck out of them if you want. Both Scripts & logos are within the Logo directory. The tar.gz is a collection of all scripts + logos.

The Logos

Here is a set of six ( {LHS | Centre | RHS} top + bottom ) each in “NimbusSans-Regular” font:–

Left-Hand-Side	Centre	Right-Hand-Side

…and then, just because we can, here is the same set of 6 but with a narrow version of the same font:–

Left-Hand-Side	Centre	Right-Hand-Side

The Scripts

This is the combo of IM6 Script + the PNG that that script will produce (in the same order as above):

Left-Hand-Side	Centre	Right-Hand-Side
Top:
convert-lhs ＝＞ devuan-powered-by-lhs.png	convert-centred ＝＞ devuan-powered-by-centred.png	convert-rhs ＝＞ devuan-powered-by-rhs.png
Bottom:
convert-lhs-bottom ＝＞ devuan-powered-by-lhs-bottom.png	convert-centred-bottom ＝＞ devuan-powered-by-centred-bottom.png	convert-rhs-bottom ＝＞ devuan-powered-by-rhs-bottom.png
Top Narrow:
convert-lhs-narrow ＝＞ devuan-powered-by-lhs-narrow.png	convert-centred-narrow ＝＞ devuan-powered-by-centred-narrow.png	convert-rhs-narrow ＝＞ devuan-powered-by-rhs-narrow.png
Bottom Narrow:
convert-lhs-bottom-narrow ＝＞devuan-powered-by-lhs-bottom-narrow.png	convert-centred-bottom-narrow ＝＞ devuan-powered-by-centred-bottom-narrow.png	convert-rhs-bottom-narrow ＝＞ devuan-powered-by-rhs-bottom-narrow.png

Editing the Scripts

A little bit of help to get you going should you wish to edit one or more of the IM6 scripts.

ImageMagick Fonts

These scripts were written for IM6 (current version is IM7; there are some differences):

$ convert --version

The very first thing that you may wish to do is to grab the current Devuan logo (one is already within Logo, but this is me being super careful):

Please note that the logo-background is transparent (set as alpha-transparency). Note also that all scripts are set to render their PNG file in the exact same mode.

The item that most folks may wish to change is the font for the text “Powered by”. Fonts are perhaps one of the most iffy aspects of IM6, so let's try to explain what to explore & what you may need to do.

The following code will show fonts currently registered in IM6 on your system & also IM6-specific local setup:

$ convert -list font | head

Path: /etc/ImageMagick-6/type-urw-base35.xml
  Font: AvantGarde-Book
    family: AvantGarde
    style: Normal
    stretch: Normal
    weight: 400
    glyphs: /usr/share/fonts/type1/urw-base35/URWGothic-Book.t1
$ convert -list font | fgrep Font: | wc -l
2919
$ fgrep -c '<type name=' /etc/ImageMagick-6/type-urw-base35.xml
34

So, I have a terrifying 2,919 fonts available to IM6 in my Desktop machine, whilst IM6 has just 34 fonts registered within it's local XML file. The non-narrow font used within the scripts is NimbusSans-Regular & that appears to come from amongst those 2,919 fonts (as does the narrow version):

$ convert -list font | fgrep 'Font: NimbusSans-Regular' -A 5
  Font: NimbusSans-Regular
    family: Nimbus Sans
    style: Normal
    stretch: Normal
    weight: 400
    glyphs: /usr/share/fonts/opentype/urw-base35/NimbusSans-Regular.otf

If you do not have any fonts already registered in IM then look at Mark Setchell's answer but otherwise maybe just precede the fontname with an “@” (see the CLI font help).
