img2data
|
|
--------
|
|
|
|
img2data is a helper program to convert images to binary data for embedding in
|
|
software. The generated data is used in nsxiv to set the window icons.
|
|
|
|
|
|
How It Works
|
|
------------
|
|
|
|
Each given image is compressed using run-length encoding and a data array is
|
|
generated. In these arrays, the four high bits of each byte are the run length
|
|
minus one and the lowest four bits are the data, which are indices for the
|
|
color array.
|
|
|
|
See `data.gen.h` or the output of img2data for a better understanding.
|
|
|
|
|
|
Dependencies
|
|
------------
|
|
|
|
img2data requires Imlib2 to be installed.
|
|
|
|
|
|
Building
|
|
--------
|
|
|
|
img2data is built using the command:
|
|
|
|
$ CC -Wall -std=c89 -pedantic -lImlib2 img2data.c -o img2data
|
|
|
|
where `CC` is a C compiler such as `gcc`.
|
|
|
|
|
|
Usage
|
|
-----
|
|
|
|
img2data is used as the following:
|
|
|
|
$ ./img2data 16x16.png 32x32.png 48x48.png 64x64.png 128x128.png
|
|
|
|
You may replace or omit any image, but you must have a `data.gen.h` with at
|
|
least 1 image for nsxiv to compile.
