only svg output right now? and a gui bug

[MeraX]

After solving the compiler problems, I played around with InklingReader and found two bugs:

$ ./InklingReader -f ../SKETCH5.WPI -t ../s5.svg
$ ./InklingReader -f ../SKETCH5.WPI -t ../s5.png
$ ./InklingReader -f ../SKETCH5.WPI -t ../s5.pdf

These commands always create a svg file regardless of the given extension.

When opening SKETCH5.WPI with the gui it looks like: which is actually not what I draw. When I export this via the gui different file formats work, but they also only show these bars. And during the loading of the dialog window for opening and closing InklingReader uses a lot of my CPU.

Never the less converting wpi to svg on the command line works very well and I'm very happy.

Thank you for your report once again. Yes, the command-line can only export to SVG at the moment. Unfortunately I think when I make the modifications to allow other formats it will only draw these bars as well.

I've seen the buggy GUI behavior on a Windows build as well. I'm actually clueless at what this could be at the moment. Are you interested in testing future versions to try to solve this?

[MeraX]

I prefer converting the wpi files to svg and then post process them with other tools. Like editing them with inkscape oder converting them with imagemagics convert to other formats. If you do updates every now and than, I could test the gui, but I'm more interested in the CLI.

I'm just thinking, weather it would be possible also to export the pressure. But i think svg doen't support something like stroke width right now.

[roelj]

Ok. Fortunately that works :)

I've been thinking about stroke pressure as well. I can extract the stroke pressure from the WPI file, but I'm not sure how to convert that to something in SVG.

How it works now is:

<start of stroke> <move to point (x1,y1)> <draw a line to point (x2,y2)> <draw a line to point (x3, y3> ...

I guess to make it possible to handle stroke pressure, I would need to draw an outline and fill that (but I don't know how to do it).

Either way, I'm a step closer to solving the GUI bug: I found out that the problem is in the combination between Rsvg and Cairo.

[roelj]

Could you try the GUI with the latest code in 'master'?

EDIT: I added the ability to export to other formats from the command-line as well.

[MeraX]

The Gui works. The open and export dialog is faster and the displayed picture is correct. export to png works, but in pdf it cuts off something on the right hand side.

But the CLI converting doesn't work anymore:

It is probably just a small bug anywhere.

[roelj]

I can confirm the issues on Ubuntu. I'm working on a fix.

[roelj]

The current 'master' should fix all the above problems. I tested and verified this on Ubuntu 12.04.

[MeraX]

yeah, now it works as supposed.

I have just one little confusion with the argument options:

$ ./InklingReader -g ../SKETCH19.WPI
# starts gui wich SKETCH19 shown
$ ./InklingReader --gui ../SKETCH19.WPI
# strats gui ignoring the file name
$ ./InklingReader -g
./InklingReader: option requires an argument -- 'g'
# doesn't start anything.

I think the gui should start even with -g and the file should also open wich --gui. Maybe you should leave out the -f argument so that the fist argument that has no - in front is the inputfile and than you can also leave out the -t, because the second argument that has no - is automatically the outputfile. If there is a -g or -gui in front of the inputfile, use gui.

[roelj]

Sorry for this confusion. I'm trying to keep it compatible with GNU programs. These are equivalent:

./InklingReader -g ../SKETCH19.WPI
./InklingReader --gui=../SKETCH19.WPI

(long options need a '='). They will both open the file.

Long options (--gui) are used to set a variable in the program. Not setting a value can be captured by the program as if the value for it is "true". Short options can be combined (For example: tar -zxvf) and often one of the options needs an argument (like tar's -f option).

This is the default behavior for GNU programs, which I am trying to stay compatible with.

To create the behavior you want you could also create an alias, and for leaving multiple options out, maybe a bash function that parsed the options with awk. (I can provide examples if you want).

Is it OK with you if I don't change the way arguments are processed?

[MeraX]

yeah, I'm fine with that.

[roelj]

Thanks. I'm going to close this issue since the bugs are fixed.
