Hi.

Yesterday I updated one of my Claras from firmware 4.26.16704 to the current 4.30.18838 and I'm having issues with font sizes.

The problem is that I have all my Claras set to the same margins, font, font size, line spacing and the rest of the reading layout stuff, but with the 4.30.18838 unit I'm unable to get the exact same font size I have in my other Claras. One step in font size is smaller than the font in the 4.26 Claras I'm using as a reference and the following is bigger. I'm testing with the same kepubs in all 3 devices.

I'm using the "Custom font sizes" patch, along with "Enable advanced settings for all fonts". Looking at libnickel.so.1.0.0.yaml, it says about the "Custom font sizes" patch that

# This patch was rewritten for 18220 by @shermp.

I guess that this is what is making font sizes different between 4.26 and 4.30. I'm wondering if I can alter the patch values to match the sizes produced by the "Custom font sizes" patch over older firmwares such as 4.26.16704.

This is pretty cryptic to me:

Custom font sizes:
- Enabled: yes
- Description: |
Changes the range of sizes on the font size slider so that there are more of
the small sizes and fewer of the large sizes.
With this patch enabled you will not be able to select the very large font
sizes, but will be able to make finer adjustment to the smaller sizes.
# Font sizes depend on the device's screen density. Unpatched, the sizes
# increase in steps of 1 from the smallest size up to size 44, then in steps
# of 2 up to size 68, then in steps of 4 up to the largest size:
#
# Touch/Mini: 8px - 90px (39 steps)
# AuraHD/AuraH2O/Libra2: 8px - 150px (54 steps)
# GloHD/ClaraHD: 10px - 150px (52 steps)
# LibraH2O: 11px - 150px (51 steps)
# AuraOne/Forma/Elipsa/Sage: 14px - 195px (59 steps)
# Aura/Glo/Nia: 8px - 122px (47 steps)
#
# The example replacement values in this patch result in the following ranges,
# with increases in steps of 1 from the smallest size up to size 44, then
# steps of 2 up to size 68, then steps of 4 up to the largest size:
#
# Touch/Mini: 8px - 80px (52 steps)
# AuraHD/AuraH2O/Libra2: 8px - 108px (59 steps)
# GloHD/ClaraHD: 10px - 108px (57 steps)
# LibraH2O: 11px - 108px (56 steps)
# AuraOne/Forma/Elipsa/Sage: 14px - 132px (59 steps)
# Aura/Glo/Nia: 8px - 88px (54 steps)

#
- BaseAddress: "N3FontTypeUtil::fontSizes()"
# Initial font size:
- ReplaceInt: {Offset: 364, Find: 8, Replace: 8} # Other devices
- ReplaceInt: {Offset: 360, Find: 11, Replace: 11} # LibraH2O
- ReplaceInt: {Offset: 36, Find: 10, Replace: 10} # GloHD/ClaraHD
- ReplaceInt: {Offset: 392, Find: 14, Replace: 14} # Forma/AuraOne/Sage/Elipsa
# Increment:
- ReplaceInt: {Offset: 78, Find: 21, Replace: 43} # Add font sizes in increments of 1 until this size exceeded
- ReplaceInt: {Offset: 88, Find: 22, Replace: 44} # Continue from this font size
- ReplaceInt: {Offset: 218, Find: 49, Replace: 67} # Add font sizes in increments of 2 until this size exceeded
- ReplaceInt: {Offset: 224, Find: 50, Replace: 68} # Continue from this font size
# Now increment by +4 until final font size:
- ReplaceInt: {Offset: 410, Find: 90, Replace: 80} # Other devices
- ReplaceInt: {Offset: 414, Find: 122, Replace: 88} # Aura/Glo/Nia
- ReplaceInt: {Offset: 50, Find: 150, Replace: 108} # LibraH2O/AuraHD/ClaraHD/GloHD/AuraH2O/Libra2
- ReplaceInt: {Offset: 388, Find: 195, Replace: 132} # Forma/AuraOne/Sage/Elipsa

But I wonder if I can get my old sizes back by altering those values.
