Changing the gesture to adjust front-light on Kobo h2o

The only difference is new touch features in Glo HD firmware?¿? I had touch gestures like pinch to zoom in old sony prs T3 that is an infrared screen. I don't know why should not be supported in H2O...:

Where? I can't see that in github... Exist some issues related to device already suported but I can't see for support "new devices"(for new i mean: not supported rightnow :P )
#1761 Maybe?¿? but not comments about change light with 1 finger or something like that...

Regards.

The link at the bottom of post #10 of this thread. You should see where it was added to the milestones.

Amm ok, I somehow skipped @habeck messages. I was always reading about slide bars like:

but not about gestures. Somehow I was blind :/

I see you are actually right, there is no specific question about "one finger swipe" on Github.
I will add that question in the Github #1761 anf see what can be done.

Hey guys,

I have made a mod to the latest koreader nightly v2015.11-431. Tested on my Kobo aura H2O.

Additional Functions are:
1. Frontlight can be toggled on and off by taping the bottom left corner. And frontlight level can be adjusted by sliding up or down on the left edge of the screen (add file: readerkobolight.lua; change file: readerview.lua.lua)
2. Frontlight level is shown in the footer (change file: readerfooter.lua)

Hope someone find it useful.

Hello!

Guys, I'm looking for answers to my questions (for my Glo HD):

1. Is there a way to edit the step of adjusting Frontlight by swiping two fingers? It takes too long to set highlight from 1 to 100 value. In other words I need to increase swipe sensitivity.
there should be a way to change sensitivity of adjusting Frontlight. I guess the right option for this is FRONTLIGHT_SENSIVITY_DECRESE = 2 but if I set FRONTLIGHT_SENSIVITY_DECRESE = 1 and then reboot the device I still see the default value FRONTLIGHT_SENSIVITY_DECRESE = 2. But I'm not sure is this right option to change Frontlight sensitivity...

2. As you know the gesture to change the intensity of the Frontlight in Nickel is swiping up or down by one finger on the left side of the screen. In KoReader we have to use two fingers. So the question is how to set one finger (for Frontlight adjusting) in KoReader?


Thank you!

P.S. I use the latest KoReader nightly build (koreader-kobo-arm-linux-gnueabihf-v2015.11-431-gc0846ee.zip).

Works great, thank you!

Works, but if you change Frontlight level you need to retap the footer to see actual Frontlight level.

Unfortunately, it doesn't work for me How can I fix it? I guess the problem refers to the following (cylight.lua):

local DTAP_ZONE_CYLIGHTSWIPE = {x = 0, y = 0.125, w = 0.125, h = 0.75 }

Could someone provide the proper values for Glo HD?

Thank you!

Why not you join koreader dev team?

DTAP_ZONE_CYLIGHTSWIPE shoudn't matter, it is just the area of which it looks for swipe gesture. feel free to change it yourself.

Actually the sliding up or down dose not behave exactly the same as nickel. it will not refresh the frontlight level as you slide, but only after finishing the gesture.
So depend on the distance of the gesture, it will increase or decrease a corresponding among of light. The max is 10% per gesture. (I took the code directly from two-finger swipe). Full distance is between 12.5% of screen height from top to 87.5% of screen height fron top (in my DTAP_ZONE_CYLIGHTSWIPE) and gives the 10% of frontlight change.
Plus, I guess there is a listening time limit for koreader's swipe event, which means that you have to slide it fast!!! slowly motion does not work at all.

Sadly, I have never learned or coded in LUA before. I know Linux and bash that can help explore and read its source code.

Joining team sounds really appealing but only when after I feel comfortable with LUA and get more free time, lol. Lots of staff to learn first.

Oh, got it now! Thank you!
So it is impossible to make the same behaviour as in nickel, right?

By the way, is there a way to turn off changing pages by swiping down or up? The problems is when I use your Frontlight adjusting it sometimes involves changing pages. I believe swipe left or right is enough to change pages.

I think it is possible, but requires more ground level changes. Frontends tweaking is not enough at all.

I encountered that as well, my guess is that sometime the swipe is not totally vertical so it detect as a horizontal swipe. Maybe narrowing the width of that area will help. try change DTAP_ZONE_CYLIGHTSWIPE.w to 0.1 or 0.0625.

Oh, I was wrong and believed that there is sliding up or down to change a page Now I understand why two fingers are required by original KR firmware.
But I want to notice I've never experienced any unwanted page when I use Frontlight adjusting on nickel. That's why I believe it's a good idea to implement the same Frontlight adjusting mechanism like an nickel.

DTAP_ZONE_CYLIGHTSWIPE.w = 0.0625 works better, but sometimes pages are changing anyway... Guess I've a wrong finger! But I'm wondering why in nickel it works perfectly? The same approach I guess.

But there is one more thing. The foot info ("L:") doesn't update after Frontlight adjusting. To see the actual Frontlight level you have to change the page. Could you fix it please? Or does it also require more ground level changes?

I have updated the attachment in #20. This will be a final version from me.

This is awesome!.. many thanks for this mod, works perfect and adds a ton of functionality and ease of use.
You just made my day my friend!
