(I was slightly confused because without a clear, '' *will* get you shouted at, but the clear makes it safe).

In the mean time between 1.6.2 and 1.10.3, somewhere in the twilight zone...

Code:

[root@kindle us]# fbink -c ''
[FBInk] Enabled Legacy einkfb Kindle quirks
[FBInk] Clock tick frequency appears to be 100 Hz
[FBInk] Screen density set to 167 dpi
[FBInk] Variable fb info: 600x800, 4bpp @ rotation: 0 (Upright, 0°)
[FBInk] Fontsize set to 16x16 (IBM base glyph size: 8x8)
[FBInk] Line length: 37 cols, Page size: 50 rows
[FBInk] Fixed fb info: ID is "eink_fb", length of fb mem: 483328 bytes & line length: 300 bytes
[FBInk] Pen colors set to #000000 -> #FFFFFF for the foreground and #FFFFFF -> #000000 for the background
Printing string '' @ column 0 + 0px, row 0 + 0px (overlay: N, no BG: N, no FG: N, inverted: N, flashing: N, centered: N, halfway: N, left padded: N, right padded: N, clear screen: Y, dithered: N, skip refresh: N, font: 0, font scaling: x0)
[FBInk] Cannot print an empty string!
Failed to print that string!

...broken again?

NiLuJe · 02-17-2019, 12:10 PM

Yes, on purpose this time

.

I have to think of a better way to handle that special case though, because it's been bugging me too ;p.

NiLuJe · 02-17-2019, 06:12 PM

It'll be fixed in the next version (where in fact, fbink -c will also be enough to do that

).

NiLuJe · 02-21-2019, 04:15 PM

Released v1.11.1!

A minor rounding fix to progress bars that affected some devices, fixed the CLI tool to allow a clear screen without specifying a string (hi @Pop!

), and a few new fonts

.

parkerlreed · 02-21-2019, 06:11 PM

I see the K3 and K5 in the archive. Is K4 supported at all?

NiLuJe · 02-21-2019, 07:36 PM

@parkerlreed: Yes, with the K5 binary (and the K3, too, technically).

c.f., this handy table if you're unfamiliar with the crappy naming scheme I'm using for the TCs

Ahh thanks. Will definitely give this a shot.

Released v1.12.1!

Some corner-cases fixes when the CLI is called from a non-interactive SSH session (#32), and added the possibility of choosing the waveform update mode used when showing an image (mostly useful to enforce A2, for instance).

NiLuJe · 03-27-2019, 01:48 AM

Released v1.12.2!

A small maintenance release with a few minor fixes peppered across the code, as well as many changes to the fbdepth tool used by KOReader

.

NiLuJe · 03-28-2019, 07:37 PM

PSA: I broke < K5 support (again

) in 1.12.2, this will be fixed in 1.13.0

.

NiLuJe · 03-29-2019, 01:18 PM

Released v1.13.0!

Mainly introduces the dump/restore API

.
Also has a small performance boost for unprocessed image blitting to !legacy Kindles.
And, speaking of, unbreak legacy Kindle support

.

PoP · 03-29-2019, 03:28 PM

1.13.0

My K3 thanks you again!

Just curious, probably an intentional optimization; but the effect I was attempting with:

Code:

#!/bin/sh
#glow v0.10 2019-03-29 ==============================
#Display glowing "GLOW" using NiLuJe's fbink color features
# ʇɟǝןʎdoƆ (ↄ) PoP under Creative Commons Attribution-ShareAlike 3.0 Unported License
#Usage: glow
# currently using fbink 1.13.0

#keep the Kindle quiet
lipc-set-prop com.lab126.powerd preventScreenSaver 1  #disable screen saver
killall -stop cvm #stop framework

n=1 #repetition number
i=0 #starting color number
j=1 #color increment

while :; do

  case $i in
    0) COL="BLACK" ;;
  15) COL="WHITE" ;;
    *) COL="GRAY""$(printf  "%1x" $i)" ;;
  esac

  fbink -S 5 -F BLOCK -C $COL -O -M -m "GLOW"
#screenshot
  usleep 500000 

  i=$((i+j))
  if [ $i -gt 15 ] || [ $i -lt 0 ]; then j=$((-j)); n=$((n+1));  i=$((i+j+j)); fi
  if [ $n -eq 3 ]; then break; fi  #after glowing n times

done

#restore Kindle verbosity
lipc-set-prop com.lab126.powerd preventScreenSaver 0 #enable screen saver
killall -cont cvm #restart framework

... is ruined. The text was supposed to "glow" like this:

Click image for larger version

Name: glow.gif
Views: 209
Size: 135.0 KB
ID: 170471

But fbink seems to write the text in two pass, first it writes the text in black, then it updates the color map to the specified color. I couldn't smoothly fade-out / fade-in my text.

NiLuJe · 03-29-2019, 05:17 PM

@PoP: Just to double-check: did it ever work as you wanted it with earlier versions?

EDIT: Okay, tried it, no, don't think that's doable, that's an artifact of how eInk handles the update. I'll see if I can fiddle with different waveform modes

.

EDIT²: Yep, it's a byproduct of GC/GL waveform update modes

. And those that don't work like that do not support so 'many' colors

.
