New GTR Mini

[MGBWHIP]

Hello. Will there be new watchfaces for the new GTR Mini soon? Can any of the published faces be used for the Mini?

Thanks.

[asoo]

From the official web
https://www.amazfit.com/products/amazfit-gtr-mini

Amazift GTR Mini running Zepp OS ( Version 2.0)
Resolution 416x416

Spoiler

Same resolution as Amazfit Falcon.
OS is Zepp OS ( Version 1.0 )

So , from the example that the GTR4 can open the GTR3 dial.
I think watchface from falcon can use on GTR mini.
However, if you would like test ,You must do so at your own risk. that happend on your device

The posture that I can check now.
Found that in the GTR mini has changed the image format.

By which I test create a watch face from web zepp and take the file to check.
The png image found in the watch face file has a different structure than GTR3.
So at the moment the GTR3 and Falcon (legacy) watch faces are unlikely to work on the GTR mini.

Thank you

I tried loading the Falcon watch face. It loaded but it was unreadable. Do you know of any designers that are working on the new GTR Mini yet?

[blokfluitist]

I just got my GTR 4 Mini today! Am looking forward to being able to access more watch faces for this model very soon

[ivblumen]

has anyone been able to load Falcon watchfaces on GTR mini?

[kmi]

No it doesn't work with Falcon watchfaces, I tried a few and they all end up looking like this

The images for the GTR Mini look weird. Like they were made wrong. I would like to see a real working dial to make sure that this is not a mistake in the online editor.

[MGBWHIP]

I was able to load one of the faces on the Zepp watchface maker to the GTR Mini. I do not know enough to actually make or modify the faces. Maybe someone else could.

I have try several falcon watchface on my gtr mini none of them can use, it unreadable like this


I try making a watchface using watchface.zepp.com by start from example2 template, then scale it to 416x416 and upload to zepp app via developper modes, the watchface is work fine



Don't know why falcon watch face not work on gtr mini

[kkeonline]

I have export the watchface from watchface.zepp.com to .zap file on my pc then extract it to compare, even the screen resolution of falcon and GTRmini is the same 416x416 but there are 2 version of .zpk watch face file, NXP and MHS, the NXP is for falcon and MHS is for GTRmini

Spoiler

after extract both .zpk to compare the only difference in app.json is the DeviceSource for falcon and GTRmini, the watchface index.js is identical.

Spoiler

However modify the app.json of falcon watchface from falcon to GTRmini does not fix the problem, because all png images in the assets folder of nxp and mhs are difference, this mean falcon and GTRmini use difference png transform/encoded format, the checksum did not same

Spoiler

all png in assets folder can not open by image viewer program, this mean it not standard png format, it transform or encoded the original png file with some method and nxp and mhs are use difference method, that why the falcon watchface did not display properly on GTR mini, all png assets images has to be fix.

[ZduneX25]

I was getting the same visual glitches on other watches (gtr3/4) back when I was using 48bit png images. 32bit is max, maybe you guys try 48 or 24 on gtrmini. There is a chance it has been increased/decreased.

[kkeonline]

More on comparing png images in assets folder
between old (Falcon) and new (GTRmini) format
comparing as binary the part on beginning of file are difference then the rest are identical
this mean on GTR mini watch face it change some format of the header of png file.

Spoiler

Surprising that winmerge can read the watchface png as image, but the standard image viewer not

Spoiler

[SashaCX75]

Other image viewers can open these files too. But everywhere they look distorted. You can even see it in your screenshots. I guess it has to do with the sequence in the color map. This is clearly visible if you encode an image with a small number of colors and then change the extension to tga and look at the color map in Photoshop.

finally I success converted falcon wf to work on my gtr mini

.

I done by using amazit watchface tool to convert png files in the wf file back to standard png format, then upload all of them on watchface.zepp.com then export the wf for gtr mini, this will make the png files in correct format for gtr mini
then I have to rename all png files to match the original filename, then replace these renamed png files into original wf, then transfer it to watch.

[MGBWHIP]

Thats great. Is there a step by step instructions to do this?

Test utility for converting images to watchface format for GTR mini. Judging by the previous message in normal mode, the image is converted normally.

Who can check with the switch for forced use of the improved algorithm turned on.

Thank you. This loaded and is working

[ZduneX25]

SashaCX75 can we execute ImageToZeppOS through terminal? I would like to automate whole process and terminal command to patch images would save a lot of time.

[SashaCX75]

ZduneX25 I don't plan to add terminal mode work. A little later I will clean up the code and post it. Then whoever wants can remake it to their needs.

Now amazfaces app add the gtr mini to select


however no connect/upload button to upload the watchface


I have to copy the file to falcon folder and swap the watch selection to falcon to upload.

Regarding this, it is advisable to ask questions in this forum.
