| 16:11 | metal_dent[m] | 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
|
| 17:33 | metal_dent[m] | 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

| 19:27 | metal_dent[m] | okay, i'll look into that. Thanks!

| 19:30 | metal_dent[m] | 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°?
|
| 19:38 | shashwat | joined the channel |
| 19:39 | gsalazar | left the channel |
| 19:39 | 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 | gsalazar | joined the channel |
| 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 | shashwat | 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
|
| 19:56 | shashwat | *worried
|
| 19:56 | shashwat | 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
|
| 20:14 | BAndiT1983 | changed nick to: BAndiT1983|away
|
| 20:17 | metal_dent[m] | 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 | metal_dent[m] | BAndiT1983 : Why do we want to dissect the image into two parts (the name and the symbol)?
|
| 20:35 | shashwat | left the channel |
| 20:41 | BAndiT1983|away | changed nick to: BAndiT1983
|
| 20:41 | BAndiT1983 | 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
|
| 20:43 | BAndiT1983 | changed nick to: BAndiT1983|away
|
| 20:43 | metal_dent[m] | 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
