I made a topic about this but it was suggested I ask here.
You can read the long explanation of my request here, but the short of it is that many fonts render much better with hinting disabled. However, even if the font has no hinting instructions, Kobo forces autohinting. I'd love if there was a patch to disable autohinting Here’s an example: Quote:

Code:
body { -kobo-font-hintstyle: 1;} To confuse matters a bit the same code exists in 3 different places. One of the locations looks as if it may be part of the default CSS which is applied to all kepubs. This is probably what Geoff was referring to. I don't know what the other 2 occurrences are targetted at. I don't know much about font hinting so can't predict what results you might see. I should be able to create a patch that will let you test your theory that setting it to Code:
body { -kobo-font-hintstyle: 0;} I'll try to post a beta patch here tomorrow for you to play with. |

Here are 3 beta patches, one for each of the 3 locations where -kobo-font-hintstyle: 1; is currently present.
Add them to libnickel.so.1.0.0.yaml or wherever you normally keep custom patches for the libnickel.so.1.0.0 file. [ETA: they were created for fw 4.38.21908] They're all disabled as-is and appear to be independent of each other and any other patch so you should be able to enable/disable them in any combination you want. Please report back with any useful findings. Good luck ETA2: beta patches removed as they did not appear to be effective. Last edited by jackie_w; 04-16-2024 at 08:25 AM. Reason: beta patches removed |

Hello,
I have a personal request / suggestion / patch. I myself needed tweaks for my Kobo keyboard. I did some digging and made some alterations to keyboard layout such that it adjusts letter pop-ups. Code:
Lithuanian Keyboard (Libra 2): # Updated by driuba for 4.38.21908 - Enabled: no - PatchGroup: Keyboard alternatives - Description: | Replaces some of the keys on the Extended Latin keypad with Lithuanian alternatives. This is mainly intended to edit the popup tooltips. Note that after the device boots, the keypad might just show blank squares until after the first book has been opened. Also note that long-pressing keys on the base keypad will no longer show the appropriate list of Extended Latin keys. # Change keyboard layout - FindBaseAddressString: "¡\0\0¿\0\0«\0\0»\0\0" - ReplaceString: {Offset: 0x4c, Find: "â\0", Replace: "ą\0"} - ReplaceString: {Offset: 0x64, Find: "ê\0", Replace: "ę\0"} - ReplaceString: {Offset: 0x68, Find: "ë\0", Replace: "ė\0"} - ReplaceString: {Offset: 0x90, Find: "ï\0", Replace: "į\0"} - ReplaceString: {Offset: 0xa0, Find: "ü\0", Replace: "ū\0"} - ReplaceString: {Offset: 0xa8, Find: "ç\0", Replace: "č\0"} - ReplaceString: {Offset: 0xb8, Find: "ą\0", Replace: "â\0"} - ReplaceString: {Offset: 0xc4, Find: "ę\0", Replace: "ê\0"} - ReplaceString: {Offset: 0xcc, Find: "ů\0", Replace: "ų\0"} |

I'm not sure whether you know this but you can split off your libnickel personal patches into a separate custom .yaml file (e.g. libnickel_driuba.yaml) and edit the kobopatch.yaml file to include this extra yaml. In this way you can carry over the pre-customised personal patches (often unchanged) from firmware to firmware. If this appeals to you I could help you set it up for yourself. It takes longer to explain it than to do it. Here's a link to an old post where I attempted to explain it to another user. |

Hello, I'm new to the forum. I haven't had an e-reader until now, I'm thinking about buying a new Libre color. Is there a possibility of putting some other program for taking notes, I am most interested in inserting or Copy/paste pictures im notes? Tnx

Oh, well! It was worth a try. I'm going to remove the 3 beta patches from the earlier post as there's no point anyone else wasting their time.

This doesn't mean that some enterprising Kobo developer(s) won't create something more substantial in the future. Much like some of the more ambitious community projects, e.g. KOReader, NickelMenu etc. |

Also the Nebo bought in note taking for Basic and Advanced Notebooks is one of the top ones, but exposes the limitations of eink. It's very cut back. It doesn't even reliably copy/paste text on Kobo eink. It has a lot more features on the paid iOS version, the Android (digitiser needed) and Windows version (Surface 3 or later, or screen digitised not a separate Wacom tablet). So even Kobo, who have good software, have not done more than a sketchpad with save / view in SVG and no edit after save and no copy/paste. None of their annotation (text based or pen, epub or PDF) even supports copy/paste. You need iOS, Andriod, Mac OS, Windows or Linux and eink with Android is too poor for that sort of interaction. Also even the colour eink is very poor for photographic images (they'll look a bit better on mono eink due to x2 resolution and your eyes are too sensitive to hue/saturation distortion of the colour eink. |

The eink is nearly 5000x slower than fastest OLED/LCD for pixel response/change and frame rate (without much gray scale) about 20x slower than many tablets. Like LCD, the Kaleido color used on the Libra Colour is a coloured dye filter on a monochrome panel, so the mono Libra 300 dpi is reduced to 150 dpi. LCD makers haven't quoted native mono pixel resolution under the colour filter for maybe 30 years. |
