chore(color): conversion helper tool and file cleanup

[JimB40]

This PR

• integrates Figma as source for SVG graphics
• automated PNG build for color LCD radios via covert-gfx.sh

Summary of changes:

1. changed img-src files names & folder structure

• files follows naming <bmp_|mask_><type_>.svg scheme that follows Figma UI Design scheme
• bmp_ & mask_ prefix defines PNG type
• no subfolders to simplify PNG generation & review
• all SVG vector sources simplified end re-exported to img-src

2. Replaced PNG

• PNGs now have new names
• unused PNGs are removed
• conversion done using rsvg-convert for smaller size

3. Modified CMakeList.txt

• simplified

4. Modified *.cpp

• all *.cpp with *.lbm references are updated to reflect naming change
• _BuiltinIcon names left untouched to avoid conflicts (lots of changes in code)

5. tools script to convert SVG to PNG

• changed script name to convert-gfx.sh
• added --resvg param to force using resvg insted of rsvg-convert (testing)

Other PRs @pfeerick

• this affects feat(color): allow user to change key shortcut actions and add Favorites quick menu #6753 so probably this one should be merged first ?
• will close Alternate convert script fixes #6779
• may close chore(color): helper script to convert SVG firmware graphics to PNG #6772 :)

Figma Integration

• left > Design window
• right > Export SVG window

Any changes in Design window are automatically refleced in Export SVG window that converts graphic to specified type (normal PNG or mask PNG)

Ok, so finally looking at this @JimB40 🤣

I think you had doubled up on the CSV/script file... I think tools/convert-gfx.sh and tools/convert-gfx-list.csv were the old files? With tools/png-radio-fw.sh and tools/png_radio_fw_list.csv being the new?

I've rebased this to make it merge-ready again (and hopefully didn't break something), removed those extra files, I then run --update which updated the CSV (looks like it had old file names/paths), and --build which generated smaller versions of several images.

If everything looks ok to you, should be right to merge. If that old script was just my earlier one modified, don't think there is any need to keep that... better to not add two scripts doing basically the same job - any changes needed can be made to yours as time goes on ;)

Hey thx.
Actually the other way around tools/convert-gfx.sh and tools/convert-gfx-list.csv are proper (newer)
tools/convert-gfx-list.csv includes last modified time stamp column

Hasn't noticed I left png-radio-fw.sh & png_radio_fw_list.csv

[pfeerick]

Thanks for that. Yes, my bad, the png_radio_fw just had some things convert_gfx, didn't, so added that in, and changed it to a Python script as it was already a bit long for a shell script (plus python lets you do a lot of platform-agnostic stuff in an easy to maintain manner).

It now also (among other things I probably forgot):

• has nicer UI with progress bars and elapsed times 😁
• verbose flag if you really need the file lists (--verbose)
• checks if there are any orphaned PNG files when validating (validate png, validate all)
• validation will now also tell you if there is an SVG that isn't in the CSV file (validate svg, validate all)
• allows you to delete PNG files that no longer have a matching SVG, and optionally SVG files not referenced the CSV (cleanup, cleanup --include-svg)
• allows for a dry run so you can see if any changes would be made by make or cleanup (--dry-run)
• allows you to update the CSV with new SVGs (update-list)

I'll stop fiddling with it now, and we can add to it more and make changes as time progresses.

_BuiltinIcon names left untouched to avoid conflicts (lots of changes in code)

If you really want to make changes, you can do just

https://github.com/JimB40/edgetx/blob/ad9ffaa482dc622acaa1b7556ec3354b323b6b9c/radio/src/gui/colorlcd/bitmaps.h#L26-L147

and

https://github.com/JimB40/edgetx/blob/ad9ffaa482dc622acaa1b7556ec3354b323b6b9c/radio/src/gui/colorlcd/bitmaps.cpp#L405-L523

(or technically, just the second, with respect to the first - see the note about keeping them in the same order)

and I can probably figure out a not so painful way to do the rest (in anoher PR - let's keep this specific to the graphics and conversion helper).
