The content of subsys/fb/cfb_fonts cannot be replicated by the existing script due to lack of positioning options and use of a full-color frame buffer, which affects the generated bitmap. Switch to the solution used in the original script, add the required options, and document the process of regenerating the fonts. This commit also determines the required bounding box for the glyphs to be sure that the user-provided value is sufficient to avoid partial characters. Ideally the calculated width and height would be used for font characters, but this would require significant restructuring of the script to make calculated values available at the point where the arguments are used to produce output.

The DroidSansMono.ttf font used to generate the cfb_fonts bitmaps can be
|
|
obtained from:
|
|
|
|
https://android.googlesource.com/platform/frameworks/base/+/master/data/fonts/DroidSansMono.ttf
|
|
|
|
To reproduce the font bitmaps use these commands:
|
|
|
|
${ZEPHYR_BASE}/scripts/gen_cfb_font_header.py \
|
|
-i DroidSansMono.ttf \
|
|
-x 10 -y 16 -s 14 --center-x \
|
|
-o cfbv_1016
|
|
${ZEPHYR_BASE}/scripts/gen_cfb_font_header.py \
|
|
-i DroidSansMono.ttf \
|
|
-x 15 -y 24 -s 22 --center-x --y-offset -2 \
|
|
-o cfbv_1524
|
|
${ZEPHYR_BASE}/scripts/gen_cfb_font_header.py \
|
|
-i DroidSansMono.ttf \
|
|
-x 20 -y 32 -s 30 --center-x --y-offset -3 \
|
