Libvirt Logo README
|
|
===================
|
|
|
|
The master SVG files were created in InkScape, using the Overpass font from Red
|
|
Hat:

Logo formats
|
|
============
|
|
|
|
The following SVG files are provided, along with standard bitmap sizes in PNG
|
|
format:
|
|
|
|
- logo-base.svg
|
|
|
|
The basic "sardine tin" graphic used to create the other forms of the
|
|
libvirt logo.
|
|
|
|
The tin is rotated by 20 degrees, so its angle matches the angle of the left
|
|
side of the letter "v" in the Overpass font
|
|
|
|
Never use this logo file directly. It exists merely as a base for building
|
|
the other logos
|
|
|
|
|
|
- logo-square.svg
|
|
|
|
The minimal square format logo for libvirt. Simply embeds the word "libvirt"
|
|
into the basic logo graphic.
|
|
|
|
This is intended for use where a compact, square format representation of
|
|
the logo is required.
|
|
|
|
Bitmap sizes: 64, 128, 192, 256 px square
|
|
|
|
|
|
- logo-square-powered.svg
|
|
|
|
A variant of the square logo for use by 3rd party applications, to advertize
|
|
their use of libvirt.
|
|
|
|
Bitmap sizes: 64, 128, 192, 256 px square
|
|
|
|
|
|
- logo-banner-light.svg
|
|
|
|
A wide banner format of the logo. Embeds the words "libvirt virtualization
|
|
API" into the basic logo graphic. The text is rendered in a light color, so
|
|
suitable for placement over a dark background.
|
|
|
|
Bitmap sizes: 257x92, 800x286 px
|
|
|
|
|
|
- logo-banner-dark.svg
|
|
|
|
A wide banner format of the logo. Embeds the words "libvirt virtualization
|

PNG file creation
|
|
=================
|
|
|
|
The bitmap images should not be created in Inkscape, since its anti-aliasing of
|
|
the rendered bitmaps is too aggressive, resulting in fuzzy images. Instead the
|
|
GIMP is used to create bitmaps as follows:
|
|
|
|
- File -> Open, select the SVG file
|
|
|
|
When prompted for the image size, enter 1024 as the width and allow height
|
|
to be auto-set based on aspect ratio
|
|
|
|
- Image -> Scale Image
|
|
|
|
Enter desired final bitmap size and use "Cubic" as scaling method.
|
|
|
|
- File -> Export As
|
|
|
|
|
|
It is important to let GIMP render initially at 1024 and then scale down, rather
|
|
than rendering directly at the target size, since this the manual scaling step
|
|
produces better quality
