## To update the copyright on splash screens ##

There are currently five splash screens, four of which have a copyright year on them:

	index	screen
	-----	--------------------------
	1	Versiv (release version)
	2	Rescue mode (no copyright date)
	3	Versiv (with unreleased code warning)
	4	DSX-600/Dragonfly (release version)
	5	DSX-600/Dragonfly (with unreleased code warning)

### Update copyright year ###

1. Make a temporary copy of fnet_copyright.xcf
2. Using Gimp 2.10, open fnet_copyright.xcf
3. Change copyright year (using text tool)
4. Save
5. Verify the font looks similar to the original file (see below for font settings).
6. Export fnet_copyright.png (using default value, plus "Save layer offset" enabled).

### Rebuild the splash screens using ImageMagick

1. Run `make magick-compose-logos`
2. Visually check images by comparing with backgrounds
   For example like this: `feh logo_fnet_?.ppm logo_fnet_?_clut224.ppm`

### After any splash screens have been changed, do the following ###

1. Rebuild linux, check in changes.
   NOTE: Do not commit changes to original logo_fnet_1.ppm or
   logo_fnet_4.ppm by accident.
2. rm logo_fnet_?_tmp.ppm and logo_fnet_?r.ppm

If only updating the copyright year, normally only the following files should
be modified and committed:

	fnet_copyright.xcf
	fnet_copyright.png
	logo_fnet_1_clut224.ppm
	logo_fnet_3_clut224.ppm
	logo_fnet_4_clut224.ppm
	logo_fnet_5_clut224.ppm

For more details and an alternate way of doing the above, look at previous
versions of this README file.

Creating new splash screens:
---------------------------
Used GIMP to convert the graphics file format and edit copyright.  Creative
services provided the splash screens for indicating released firmware as .pbm
and .png files.  The .pbm files could not be opened by GIMP, so the .png files
were first converted to .ppm files by doing this:

1. Open the .png file for the Versiv splash screen.
2. Use File->Export to export to logo_fnet_1.ppm and select ASCII
   format when prompted.
3. Repeat with Dragonfly logo screen, export as logo_fnet_4.ppm.
4. Commit the new files without copyright info to use as the originals.

It will probably be necessary to reduce the number of colors in the images:
5. ppmquant 222 logo_fnet_1.ppm > logo_fnet_1r.ppm
6. ppmquant 222 logo_fnet_4.ppm > logo_fnet_4r.ppm

---------------------------
How the copyright file was created
---------------------------
1. Open a new 250px wide x 200px tall image with transparent background (i.e.
   under "Advanced Options", set "Fill with" to "Transparency").
2. Select Text tool.
3. Select Font Arial Italic (FreeSans Italic or FreeSans Oblique), font size 18 px,
   1px letter spacing.
4. Set color to rgb 0xddab17 (221, 171, 23).
5. Enter the following text, right justified in the lower right corner:

  Copyright  2011-2019
      Fluke Corporation

6. Save file as fnet_copyright.xcf
