| 10:25 | BAndiT1983 | DevendraKharolia: where can we find the challenge code of your solution?
|
| 11:14 | DevendraKharolia | Here is my forked repository with all the code changes and addition : https://github.com/Ddevendra/AXIOM-Remote/tree/2bitIconChallenge%40Devendra

|
| 11:19 | se6ast1an | do you have a screenshot for us of your football?
|
| 11:19 | se6ast1an | in the visualizer
|
| 11:19 | se6ast1an | I see you even implemented opacity as parameter as bonus, nice!
|
| 11:20 | DevendraKharolia | i have screenshot of the other image (navigation icon) , football's image is little bit messed up
|
| 11:20 | se6ast1an | sure, other image screenshot would also be nice
|
| 11:21 | BAndiT1983 | how was the conversion done?
|
| 11:24 | BAndiT1983 | could you also add a description of used drawing algorithm, please. am seeing 3 loops and am wondering why the third one is required
|
| 11:26 | BAndiT1983 | what could also improve the readability is the use of a formatter, we already have clang-format settings included in our repo

| | 11:30 | BAndiT1983 | is the black border in the image? or do you draw it additionally? as for icons we want to be able to have them without background
|
| 11:30 | vinayak | left the channel |
| 11:31 | DevendraKharolia | <BAndiT1983 "could you also add a description"> It's similar to DrawIcon function
|
| 11:31 | BAndiT1983 | maybe, but what is the prupose of the third loop
|
| 11:33 | DevendraKharolia | <BAndiT1983 "is the black border in the image"> I draw it to see the icon clearly, border can be removed
|
| 11:35 | BAndiT1983 | ok, sounds plausible, but it would be also interesting to see it against other backgrounds, like menu gray or white
|
| 11:37 | DevendraKharolia | <BAndiT1983 "ok, sounds plausible, but it wou"> sure, I will add the screenshot for that too
|
| 11:38 | BAndiT1983 | thank you

| | 12:02 | BAndiT1983 | great! loooks good!
|
| 12:03 | BAndiT1983 | now we need some description regarding conversion and drawing, to be able to follow the ideas
|

| 17:00 | se6ast1an | MEETING TIME
|
| 17:00 | se6ast1an | who is here?
|
| 17:00 | eppisai | is here!
| | 17:00 | Bertl | is here ...
| | 17:00 | BAndiT1983 | is here
| | 17:00 | pvcodes | where is the meeting
|
| 17:01 | se6ast1an | the meeting is here
|
| 17:01 | BAndiT1983 | you're in the middle of it actually
|
| 17:01 | Shohei | is here
| | 17:02 | se6ast1an | eppisai: do you want to start?
|
| 17:02 | eppisai | ohk!
|
| 17:02 | eppisai | As, I had mentioned last week, 2 bit image drawing was working properly when we converted the svg to xbm( it is worked fine for images that i was converting to 4 indexed c array using online tools provided in task description)
|
| 17:02 | eppisai | so sebastian had suggested, we need to optimize the conversion process, So i read about what could be wrong, tried other ways, but had no luck..
|
| 17:03 | eppisai | So,at last i read and found that xbm is a monochrome ,black and white format hence can't be used in 2 bit image. I searched for the alternative to xbm, but alernatives i found weren't storing data in binary (but ascii).
|
| 17:04 | eppisai | sebastian and BAndiT1983 come up with the approch on how to have conversion that involes extension of icon.h and another pytho script for templating, so i was just trying to write the script

|
| 17:05 | eppisai | The resources BAndiT1983 had provided in doc file, were using matplotlib library of python..but
|
| 17:07 | Cscar | joined the channel |
| 17:07 | Cscar | Hi
|
| 17:07 | BAndiT1983 | hi
|
| 17:07 | eppisai | matplotlib can't be used for manipulation of vector graphics, so, using other tools to open svg,then using matplotlib,to convert the img to 2 bit c array (conversion process was there in resorces )
|
| 17:08 | BAndiT1983 | eppisai: i would suggest to check the methods again, as matplotlib is not required and there are better libs for it
|
| 17:08 | BAndiT1983 | have in fact written a small prototype, so you can align with me to get an idea how to approach that topic, we can do it after meeting here, so other also see it
|
| 17:08 | eppisai | ohk! great! :)
|
| 17:09 | eppisai | thanks BAndiT1983!
|
| 17:09 | BAndiT1983 | no problem
|
| 17:09 | eppisai | so that it from my side :)
|
| 17:10 | se6ast1an | thanks eppisai, discussion with BAndiT1983 afterwards sounds good
|
| 17:10 | se6ast1an | Shohei: any news from your side?
|
| 17:11 | Shohei | Thank you. Here are some small progress from my side.
|
| 17:11 | Shohei | 1.I'm translating the "Join the Team" page to Japanese with Rex:
|
| 17:11 | Shohei | https://wiki.apertus.org/index.php/Join_the_Team
|
| 17:11 | Bertl | eppisai: note that ImageMagick does a nice job converting svg to bitmaps
|
| 17:12 | Shohei | Hopefully, I'm going to finish it these two weeks.

|
| 17:15 | Shohei | That's all from my side.
|
| 17:15 | Shohei | Thank you.
|
| 17:16 | eppisai | Bertl, I haven't tried to convert it with imagemagick, But i am very much familer with magick..so will explore! :)
|
| 17:16 | se6ast1an | thanks Shohei!
|
| 17:16 | BAndiT1983 | imagemagick does not give the desired output, so we have opted for python, ass we need processing there

| 17:17 | se6ast1an | BAndiT1983: but if the python ode can deal with pixel images (bitmaps) already vector graphics can be converted to pixels first (maybe dowscaled first for increased sharpness)
|
| 17:18 | se6ast1an | BAndiT1983: do you also want to share news?
|
| 17:18 | BAndiT1983 | my code is converting from SVG to image already, so it's very well possibler
|
| 17:18 | BAndiT1983 | yep, can do
|
| 17:18 | BAndiT1983 | was mostly fiddling around with the SAME70 MCU and am getting quite nice results there, am planning to port the remote firmware to it
|
| 17:19 | BAndiT1983 | trying to understand it's registers for USB, but already getting right logs regarding the SETUP packet
|
| 17:19 | BAndiT1983 | additionally we, me and se6ast1an, were fixing some small mistakes in the BOM and adjusting the script for cross-checks and verification
|
| 17:19 | BAndiT1983 | that would be it
|
| 17:20 | se6ast1an | many thanks!

|
| 17:20 | Pranjal | left the channel |
| 17:20 | se6ast1an | we started some gsoc promotion recently with a german/english text to send to universities and user groups
|
| 17:21 | se6ast1an | today me and metal_dent[m] participated in a live stream event called spring of code and did a project presentation there and answered questions regarding GSoC and contributing : https://www.youtube.com/watch?v=gHhdlwS6fUc
|
| 17:22 | se6ast1an | regarding hardware production the last remaining parts that tele ordered should have arrived today or tomorrow at the latest, so prodcution start should really be very soon eventually now
|
| 17:22 | se6ast1an | there are some efforts to build an open hardware stereo3d rig (fabian puttinger emailed us some time ago)
|
| 17:23 | se6ast1an | as efforts to get a real stereo 3d mirror rig are still hampered by covid I now started to do research online and hope for more people to join in
|
| 17:23 | se6ast1an | message me if this is interesting for you
|
| 17:24 | se6ast1an | I think thats it from my side
|
| 17:24 | se6ast1an | Bertl ?
|
| 17:24 | Bertl | well, I spent my time on reworking Beta hardware
|
| 17:25 | Bertl | mostly cleaning and testing the boards we got from Felix as well as what we have in the 'original' remote Beta
|
| 17:26 | Bertl | the planned ZIF SFE didn't work out so far, there are some unknown issues, but I'm confident that we can figure this out
|
| 17:26 | Bertl | other than that, not much which was done this week
|
| 17:27 | Bertl | that's it from my side
|
| 17:27 | se6ast1an | thanks!
|
| 17:27 | se6ast1an | anyone else with topics/reports?
|
| 17:27 | se6ast1an | Cscar: any news?
|
| 17:29 | Cscar | No, I'll call the bookkeeper tomorrow to see how things are for taxes
|
| 17:30 | Cscar | (as our tax year ends on the end of this month in stead of December)
|
| 17:30 | se6ast1an | OK
|
| 17:30 | Cscar | I'll report back when I know more ;)
|
| 17:31 | se6ast1an | many thanks everyone who participated, MEETING CONCLUDED
|
| 17:31 | Bertl | thanks for the moderation!
|
| 17:31 | eppisai | Thanks!
|
| 17:31 | Shohei | Thanks a lot!
|
| 17:31 | Cscar | One last thing: RS order was successfully cancelled.
|
| 17:32 | Shohei | left the channel |
| 17:33 | se6ast1an | ah, great Cscar
|
| 17:33 | se6ast1an | and the last order that arrived was forwarded?
|
| 17:34 | eppisai | Hi,BAndiT1983 are you using Pillow module for python script? I was thinking of using it(PIL) or openCV but resorted with matplotlib..
|
| 17:34 | Cscar | Not yet. Scheduled for tomorrow. Troubles with the pickup again.
|
| 17:35 | BAndiT1983 | eppisai: PIL is also used, but it depends what is required (have checked some ways in the prototype), for SVG there is e.g. cairosvg
|
| 17:38 | eppisai | oh.. can you share your prototype, or the process on how you have done it? :)
|
| 17:39 | BAndiT1983 | prototype cannot be shared currently, as it's a challenge for the students to develop some conversion process and to describe how it improve our current one
|
| 17:40 | BAndiT1983 | but the process is simple, load SVG, convert bit depth to the required one and use a template file to output a .h file with image data and additional icon info
|
| 17:41 | BAndiT1983 | cairosvg already has svg2png(), so everything else shouldn't be a big problem
|
| 17:41 | BAndiT1983 | haven't finished the prototype yet, as it was just a quick shot
|
| 17:43 | eppisai | :DThanks! was using svgutils now, but again will evaluate the approch to check if matplotlib is even needed or other modules that i can use to work directly with svg.. :)
|
| 17:44 | BAndiT1983 | matplotlib is used for different things, so not sure it is helpful at all
|
| 17:45 | BAndiT1983 | svgutils doesn't seem to convert from SVG to pixel array or similar, so it's probably also not suitable
|
| 17:47 | Cscar | Have to go! 'See' you all!
|
| 17:47 | se6ast1an | bye Cscar!
|
| 17:47 | Cscar | left the channel |
| 17:48 | BAndiT1983 | eppisai: pyvips is also a possible alternative, but haven't checked it out yet
|
| 17:53 | eppisai | matplotlib had provided me with a 2d list of each pixel, and value of each pixel was between 0 and 1 , each color stream was also provied different list, so instead coverting it to 4 index colors, I was converting it to four shades, and any color platte could have been used to draw the image in remote, then was making a c array, and templating it to a .h file, in the process, their was rgb to grey conversion and other process etc.. and now as i am typing
|
| 17:53 | eppisai | i have realized lot of functions and processes may not be neccsary, and I should devise proper way of doing after researching..
|
| 17:55 | BAndiT1983 | biggest advantage of python is the availability of modules which already cover a lot of things, like color conversion
|
| 17:55 | Bertl | off for now ... bbl
|
| 17:55 | Bertl | changed nick to: Bertl_oO
|
| 17:56 | BAndiT1983 | so you can check out which ones are suitable and require less effort
|
| 17:56 | eppisai | : D yea.. Thenks! Will do proper research this time before jumping to code ! :D
|
| 17:57 | se6ast1an | also note that there is no requirement to convert everything/anything possible to a 2 bit image
|
| 17:57 | se6ast1an | the icons will be specially designed/prepared how we need them
|
| 17:57 | se6ast1an | we will not want to convert photographs we captured for example...
|
| 17:57 | BAndiT1983 | yep, mostly black and white
|
| 18:02 | eppisai | ohk.. I thought we would be converting icons only.. because anti aliasing looks good in GUI..
|
| 18:03 | BAndiT1983 | just tried with a color icon, works also fine, output size is selectable etc., so cairosvg together with PIL works rather fine, cannot warranty that we won'T discover quirks regarding colors etc., but form first tests very promising
|
| 18:03 | BAndiT1983 | do you mean the corners of the buttons, which are jaggy?

| 18:06 | eppisai | Not just buttons any corner, for example checkbox icon
|
| 18:06 | BAndiT1983 | we can convert them also, but we can also improve button drawing by using 9-slicing -> https://en.wikipedia.org/wiki/9-slice_scaling
|
| 18:07 | BAndiT1983 | at the moment the round corners are calculated, but we just need a couple of options in the firmware and could prepare some data for that, this would avoid calculations and jagged edges, also with anti-aliased images it would look nicer
