ImageMagick for 2.5.8 DXG anyone?

Hello,

Does anybody have ImageMagick binary for 2.5.8 DXG?

My goal is to do e.g a (primitive) countdown clock on my jailbreaked DXG.
Best case scenario would be to do it in javascript and Web Launcher, but WL does not seem to be supported for this old device.

Plan B is to combine together 2 or more .png images with a script, and use EIPS for viewing them.

In order to merge 2 .png files on the device i have so far tried:

- python (failed to install PIL or Pillow modules for image manipulaiton, maybe its possible to compile python modules somehow since pip install is not exactly supported?)
- java (could not get awt.Paint to work fully)
-ImageMagick, tried to use a compiled binary from a buildroot version i found on the web, but i am getting 'illegal instruction' when running it..so it was compled wrongly somehow i think.

Ps i dont need a gui, just something to combine images from command line

Yup, we do.
And guess what, it is posted here.

See: "Screensaver for K2/DX/DXG/K3" archive.
Path: /ScreenSavers/src/linkss/bin/convert
(in this case, "src", indicates the source tree of binaries the install_*.bin packages are built with)

See also FBInk, which may help achieving your end goal in a somewhat more efficient manner .

Because let me tell you that otherwise, doing that in the most roundabout way possible is fantastically inefficient . (Don't use that, it's freakishly terrible ).

(My IM builds are fairly standalone-ish, but that -ish may matter here: zlib & libpng are dynamically linked, and it expects to find them in the usual ScreenSavers hack paths. Plus, IM itself expects to find some support files in a few circumstances, which, again, are setup for the ScreenSavers hack).

FBInk is completely standalone, on the other hand.

That still holds true for LuaJIT & Go bindings. Python is a tad bit more complex, but in the greater context of my Python package, it also works in a standalone-ish manner .

Thanks!

I only had to install the kindle-ss-0.47.N.tar instead of the kindle-ss-0.47.N-r15562.tar , since i did not find the DXG version in the 'snapshot' version.

But now it is there!

[root@kindle /]# cd /mnt/us/linkss/bin
[root@kindle bin]# ./convert
Version: ImageMagick 6.9.2-0 Q8 arm 2015-08-20 http://www.imagemagick.org
..
Usage: convert [options ...] file [ [options ...] file ...] [options ...] file

EDIT: Now i see the link about FBInk (and the link to the nice clock script ), i will totally test FBInk now instead of IM!

EDIT: just copied the FBink binary from kindle-usbnetwork-0.57.N-r15562.tar\kindle-usbnetwork-0.57.N-r15562\USBNetwork\src\usbnet\bin\fbink to the \ of the kindle, and it actually works OOB! (could not find a DXG version in the snapshot)

You are using a PC OS or a PC OS setting that strips the compression extension.
You need to watch out for that, some of our things can not survive that handling.

- - - - -

What do you mean by: "could not find DXG version" (you have used it several times now)?
Since the program runs, it is obviously intended for your firmware version. (these are utilities that are not hardware model dependent, only firmware version dependent).

Yeah bad way of expressing myself. Can't find a version that fits my firmware is maybe better. Got confused by install files named *dxg*.
I would like to install FBInk in a proper way and not copy it, but i failed to use the the snapshot version of USBNetwork where the FBInk is (update button is greyed out if i try to add kindle-usbnetwork-0.57.N-r15562\Update_usbnetwork_0.57.N_k2_dx_k3_install.b in)

Also, dont really understand what you mean by stripping 'compression extension'

".tar" is not the last extension in the archive's name.
".tar.xz" is the extension pair. ( .tar = type of archive, .xz = type of compression).
Some PC systems are set to uncompress anything that looks like it is compressed before the user ever sees it. Which is why you are not seeing the ".xz" compression type.

The contents of that compressed archive looks like the first attached image. (Ignore the -1 in the title bar, that is an artifact of my having the archive open in two different desktops.)

The package info of the highlighted install package is:
Code:
mszick@HP8300:~/work/USBNetwork$ kindletool convert --keep --info Update_usbnetwork_0.57.N_k2_dx_k3_install.bin

Which shows that the package is built for all Models with firmware 2.x or 3.x ..

Do you have a Frankenstein DX(G)? I.E: One that has had some version of 3.x.y firmware installed instead of 2.5.8?
OR
It could be a problem with the "target OTA" entry. NiLuJe would have to answer that, not in my pay grade.

I did see the .xz file ending in Windows that was set to show full filenames (and it seems as if 7-Zip managed to handle and unpack it nicely)

Yes, now that you mention it, my Kindle has been downgraded from a jail braked 3.x.x (can remember what exact version).

The snapshots packages are intended for use with MRPI only, which is why they cover every FW 2.x & FW 3.x devices in a single package, as @knc1 explained. (And while MRPI will honor OTA bracketing, it's irrelevant here since it's [0...MAX] ).

The binaries in the FBInk thread are all you probably need (you'll want the K3 one). As I said, it's standalone. USBNetwork basically just adds a symlink in $PATH.

----

Random remark @knc1: --info implies --keep . (I also very recently fixed some stupid behavior around --unwrap that was deleting the input in certain failure codepaths, so I definitely get the idea behind 'let's throw --keep in there just be safe' ;p).

Oops, I forgot about needing MrPI now. My bad.
(Which folks, is an example of why I rarely show up on the "answer desk" these days.)

Yup, the automatic "--keep" is a left over from years ago.
I have been using it ever since the first time KindleTool ate something I wanted to keep.

Thanks for your support, FBInk seem to work fine so far, but i will check out MRPI later also (and kindletool!).

This will sound like some high pressure sales pitch,
KindleTool packages and un-packages both our installable *.bin files and un-packages Amazon's (it could also package them, but we don't have Amazon's private key).
It has literally been under development all the years this forum has been up.

In the simplest terms, it will take an Amazon Kindle update package and turn it into a file system image (which may be mounted on any Linux system).

It isn't the only "tool" in our "tool box" but it is certainly the most important one - nearly everything depends on it.
