BAndiT1983: if I do any changes in painter how can I test it? (in the visualizer?)
16:23
BAndiT1983
hi metal_dent[m]: yes, in visualizer
16:24
metal_dent[m]
so after the changes i've to make the visualizer again or just running it again will work?
16:25
BAndiT1983
you have to rebuild of course
16:26
metal_dent[m]
okay!
16:26
BAndiT1983
it uses firmware sources, just not pic32 part
16:27
metal_dent[m]
okay okay

BAndiT1983: the current apertus image is converted in c array by which converter? I used the converter link given in the task's description but it's format is different than the current one's
17:35
BAndiT1983
as far as i remember it's GIMP
17:35
Bertl
note that you can use imagemagick for easy conversion too
17:35
BAndiT1983
yep, imagemagick works also very well, tried it yesterday
17:36
Bertl
it can be as simple as: convert in.png out.h
17:36
Bertl
(note here that the format and color space controls the output)
17:37
metal_dent[m]
okay, i'll try imagemagick then :)
17:37
metal_dent[m]
> (note here that the format and color space controls the output)
17:37
metal_dent[m]
yeah i noticed that, tried changing the current specs a little and observed the outputs

nice imagemagick examples there -> http://www.fmwconcepts.com/imagemagick/sketch/index.php

BAndiT1983 anyways, i converted the original image (logo) into 2 bit depth image and then into .h file but i noticed there are some redundant bits as 00. So should I use RLE?
19:30
BAndiT1983
can you pastebin the content? as there are many variants
19:31
BAndiT1983
usually i would expect lice 40 bytes for width, e.g. 320 / 8
19:32
BAndiT1983
but it depends on the converter of course
19:32
metal_dent[m]
i used gimp for bit depth conversion and im for array conversion
19:32
BAndiT1983
RLE would bring it even more down, but requires tests and maybe own converter
19:32
BAndiT1983
what is the size of the file?
19:34
metal_dent[m]
the original image array file (i converted that too using im) is 682.6kb
19:34
metal_dent[m]
and the 2 bit length array file is also 682.6kb
19:35
BAndiT1983
seems a bit much, original header file is 124KB
19:35
BAndiT1983
my current conversion uses like 7,5 or 8,5kb
19:35
metal_dent[m]
note: i haven't yet dissected the image in two parts as i wanted to see the results on the whole image
19:36
BAndiT1983
ah, sorry, forgot to tell that i have cut my image down to 320x96, without dissecting for now
19:36
metal_dent[m]
> seems a bit much, original header file is 124KB
19:36
metal_dent[m]
can i do RLE on it and then check the file size?
19:36
BAndiT1983
feel free
19:36
metal_dent[m]
> ah, sorry, forgot to tell that i have cut my image down to 320x96, without dissecting for now
19:36
metal_dent[m]
okay. I converted the image given in the description
19:38
BAndiT1983
have you removed alpha channel and converted it to black background and white apertus°?

metal_dent[m]
no
19:41
BAndiT1983
this should be the resulting 2-color image, it would bring down the size and also be the thing we target
19:41

19:42
metal_dent[m]
okay great, then i'll remove the alpha and add background then convert
19:43
BAndiT1983
yep, this should remove unnecessary information, our alpha would be the black background, which shouldn't be painted, but everything with 1 should, like Bertl already mentioned it's soem sort of stencil for icons, as we usually don't need full color there, also we could replace all 1's by specific color in the firmware
19:44
metal_dent[m]
okay!
19:52

Hello everyone. I want to contribute to Apertus for GSoC 2020
19:52
shashwat
Can someone help me out?
19:54
BAndiT1983
hi shashwat, in which area are you interested?
19:54
shashwat
I want to make my contribution in eMMc Plugin Firmware
19:55
shashwat
But it has stayed for GSoC since 2018 so I'm a little that it might be difficult
19:56
BAndiT1983
Bertl would be the right one to ask, he is the hardware specialist here

Thank You
19:57
BAndiT1983
many tasks seem difficult at the beginning, but with right approach and effort they are doable, even if not as 100% solution sometimes, as gsoc time is rather compressed
20:14
BAndiT1983
off for today, good night

So I removed the alpha channel and added the black background, now the size of array file is 9.2kb
20:25
metal_dent[m]
> my current conversion uses like 7,5 or 8,5kb
20:25
metal_dent[m]
I also removed the extra background and now it's 7.8kb :D
20:33

BAndiT1983 : Why do we want to dissect the image into two parts (the name and the symbol)?

metal_dent[m]: seen the logs, very good results for now
20:42
BAndiT1983
the images should be dissected to get them even smaller and look at the original logo, it has 2 colors ;)
20:42
BAndiT1983
that's why 2 images
20:43
BAndiT1983
off for real now, work awaits tomorrow, but afterwards i can answer questions again
20:43
BAndiT1983
have fun

good bye!!
20:43
metal_dent[m]
i still have something to report but you can see and answer that tomorrow :)
20:46
metal_dent[m]
i just dissected the image: one for the name and other for the symbol
20:46
metal_dent[m]
the size of the name array file is 7.5kb and symbol array is 1.9 kb
20:46
metal_dent[m]
So the total is 9.4kb but the size of the whole image is 7.8kb
22:46
Bertl
shashwat: the main reason for eMMC task being there since 2018 is that nobody picked it yet and it wasn't so important/urgent that we started working on it
