line spacing patches for 4.10.11591
My 10 line spacing values:
Spoiler:
Code:
My 10 line spacing values:
- Enabled: no
- PatchGroup: Line spacing values alternatives
- Description: |
This patch changes the values on the line spacing adjustment slider,
reducing the number of spacing options from 15 to 10, but allowing
much narrower spacing values to be set.

# The first 14 replace_float values above should allow the line spacing to be
# adjusted in increments of one pixel when using a medium sized font on a high
# resolution device. If you use a smaller font size and/or a lower resolution
# device you might find that increasing the slider one step at a time doesn't
# always result in a line spacing increase at each step. In that case, you
# might want to use replacement values that are not quite so close together.
#
# For example: (I use these values on my 758x1024 Glo)
#
# 0.7 0.725 0.75 0.775 0.8 0.825 0.85 0.875 0.9 0.925 0.95 0.975 1.0 1.025 ...
#
# or: (these might better suit the 600x800 Touch)
#
# 0.6 0.633 0.667 0.7 0.733 0.767 0.8 0.833 0.867 9.0 9.33 9.67 1.0 1.025 ...
@geek1011: If you want to start an instructions thread for this firmware version then go ahead, I can make a post in it with the old-method instructions later, this weekend sometime.

Reason: My 24 line spacing values patch is working after all
