Flat Theme Icons

[hooperfly]

Add a new set of icons for use with the GCS. The current classic icons are sometimes difficult to see against a black GCS screen(i.e. papgets). The new flat theme hopefully improves readability and adds some new icons related to rotorcraft usage vs. fixed wing.

The new flat theme icons are localized in their own directory named flat_theme in $PAPARAZZI_HOME/data/pictures/gcs_icons. Along with a new set of icons, this directory contains the master GIMP file named flat_theme.xcf.

Reference pull request #1187 for historical background.

I think we can merge this, since it my interest other people. They will not be able to switch from one theme to an other easily, but I'll try to find some time to do something in this direction later.
Is this okay for you ?

Currently, the GCS derives it's icons location from the gcs_icons_path variable set in $PAPARAZZI_HOME/sw/lib/ocaml/env.ml

let gcs_icons_path = paparazzi_home // "data" // "pictures" // "gcs_icons"

The setting of this environment variable could be exposed in an XML template. For example, the gcs_icons_path could be set via the aircraft configuration xml file.

Something like:

  <section name="GCS">
    <define name="ICONS_THEME" value="flat_theme">
    <define name="ALT_SHIFT_PLUS_PLUS" value="30"/>
    <define name="ALT_SHIFT_PLUS" value="5"/>
    <define name="ALT_SHIFT_MINUS" value="-5"/>
    <define name="SPEECH_NAME" value="Teensy Fly Hexa"/>
    <define name="AC_ICON" value="hexarotor_x"/>
  </section>

can you try the gcs_icons_flat_theme from paparazzi repo ?

Added the ICONS_THEME attribute to each aircraft files:

  <section name="GCS">
    <define name="ICONS_THEME" value="flat_theme">
    ......
  </section>

and it seems to work fine. Here's the GCS with the patch:

I also tested the flat_theme with the MicroJet. They seem reasonable.

More tests:

1. Invalid value given to the ICONS_THEME attribute

<define name="ICONS_THEME" value="nothing_theme"/>

The GCS used the default icons as expected.

2. Relative path given to the ICONS_THEME attribute

<define name="ICONS_THEME" value="../../../myawesome_theme"/>

The GCS successfully loaded and used the appropriate icons in myawesome_theme
