Please recommend a Handwriting Pad


Hi, I want to buy a handwriting pad for writing math equations or drawing graphs (with inkscape freehand pen tool). I don't care much care about OCR, I just care about the output images. Which brand of this kind of device most compatible with Linux or Slack?

Thanks in advance.

I have a usb Wacom intuos3 that works good with KDE. Here is a list and what versions of the Linux kernel are required for them to work: https://github.com/linuxwacom/input-...iki/Device-IDs

Thanks for the info. What software are you using when you want to write some math equations with some graphs along side?

I have a Wacom Cintix13 that is a very fine portable tool indeed. It is not cheap,
but it is at the lower end of Wacom's display tablets.
WYSIWYG tablet is pretty nice but it comes at a pretty price.

I use it for teaching and conferences primarily and for annotating histopathology slides.

Right now my favourite software for it is OpenBoard_1.4 .
Unfortunately it is a real bear to install in Slackware but I have it going
in Slackware64-current. There are many dependencies and libraries to add to slackware
many of which must be brought in from Ubuntu 16.04 but it is worth it.

OpenBoard can open most graphics files whole directories at a time which is great for me.
It also can save your pages in .pdf form which is great for meetings.

OpenBoard supports multiple screens, so one can display to a projector while using the pad for controlling the presentation.
If one has a 3rd monitor, the previous page is displayed there while the current page is on the main screen, which is also quite cool and useful at times.

There is a WinDoze version that works about the same as the Linux one. OpenBoard for Linux was set up for Ubuntu 16.04 and installs there quite readily. Those might be previews for those wanting to try it before the tour-de-force of installing it on Slackware. The simple dependencies and 3rd party notes on the OpenBoard website were misleading to me.
I had to convert from .deb to .tgz then install, then find the binary in the /opt directory and start ./OpenBoard and installing the deps one by one as the program crashed until the crashes stopped. There might be a better way.

You can use your mouse as the pen if you have no pen tablet.

The wacom tablet has support in Slackware64 -current and in AlienBob's plasma5 and in Cinnamon.
There is a useful utility xsetwacom which is worth getting to know to set up your tablet.

It works fine with inkscape and with gimp as well as with draw programs like LibreOffice Draw
and the annotation tools of LibreOfficeImpress.

I have this Huion writing/drawing pad; was much less expensive than wacom at the time and does the job. It has a kernel module (helped debugging it ;-) and is directly recognized by inkscape etc. It came with its pen and connects via usb (one to charge the pen, another for the pad).

I can second this recommendation that a huion works well. Mine is a Huion 1060pro+, which as far as I remember worked out of the box on Slackware.

Wow, Wacom Cintix13 is $600+, that's out of my budget too much, but thanks for you suggestion. And, I did not found OpenBoard in either slackware64-current or slackbuilds.org.

I use LibreOffice Calc/Octave for graphs and LibreOffice Math for math equations but they aren't drawn by hand. I don't use a graphics table to draw equations and graphs. LibreOffice Draw could be an option. There is Gimp, Krita, Blender grease pencil. I really like MyPaint because it has a large scratchpad to draw on.

In Plasma 5 System Settings->Input Devices->Graphic Tablet-> you can configure your graphics tablet. I know KDE 4 had something similar.

Openboard looks nice, but I would try to bypass the ubuntu.deb binary as converting it via deb2tgz (Sbo) and installing it (it goes into /opt) gives me this run-time error:
Quote:
bash-4.4$ ./OpenBoard
./OpenBoard: error while loading shared libraries: libavformat-ffmpeg.so.56: cannot open shared object file: No such file or directory
Possibly because the program depends on QT5 version 5.5 which will have been compiled against other media sources than my QT5.7.1 on current. (I have version 57 for libavformat on this box)

Building from scratch -if at all possible- could be attempted with a Slackbuild processing the source.tar.gz, that you can find here: github.com/OpenBoard-org/OpenBoard/releases.
There are instructions to build it from source, for ubuntu: https://github.com/OpenBoard-org/Ope...ld-from-source
As said, it depends on QT5.5 (so, whether the SBo version 5.7.1 will work one has to find out); libmotif; libpaper (SBo)
Third party (-for ubuntu or openboard-) packages: freetype; quazip (SBo); xpdf;
Then there is an issue with PREFIX=/usr gets ignored? that could be bypassed by editing a file used by qmake

Thus, whether it is possible to get Openboard to run on Slackware in a straightforward manner remains to be seen and will take some effort.


Alternatively, you could install the jessyink-1.5 extension into inkscape. It allows you to turn layers into presentation slides and to draw -non-permanently- on screen after loading the svg into your browser. But whether that set up is fast enough... (sometimes my stuff hangs mid-way presenting, possibly because the images I load are too big).

hth

EDIT2: Instead of openboard, you could try Xournal (SBo); I used it all the times for commenting PDFs; best to print to file when saving as pdf (the export to pdf did not work for me)

EDIT: I looked a bit further into this; for compiling via qmake one has to rebuild standard Slackware packages (the Third Party stuff). Sorry, not the time to experiment with this or skills to adapt the make instructions; what I did came across is this 'appimage' on https://github.com/probonopd/OpenBoard/releases to get a taste. Download, make executable, run; but it crashes once you try to use the browser and no video/sound works, possibly because it needs stuff not found on slackware .
