Less left margin when printing

[bllamarodri]

Hi, I use Maxima with my students, and I need to print the exams I create for them. Would it be possible for the labels %i1, %o1, etc. to appear when printing, and for the left margin to be smaller? I think it's excessive and causes many expressions to be cut off. Best regards,

Boni

Would the attached print to file output be what you want? The blank indentation between the paper edge and the cells' labels being smaller than usual (usually it's about label's width)? That seems to be regulated by #define PRINT_MARGIN_HORIZONTAL 50 in src/graphical_io/Printout.cpp. I tried setting it to 5, nothing broke, the result is attached.

Thank you very much for the help, but I am working with Windows 10, and although I find some folders named src, there is no folder named graphical_io, and no file named Printout.cpp. I also just realized that there is a problem with the integral symbol when printing.

Best regards, Boni

I was primarily addressing developers' team, to let them know about a possible solution. Printout.cpp etc. is to be found in the source code archive, not in the binary package. The question which only you can answer is, do you want that kind of the narrowed left margin, or do you want something else? Integral sign is obviously a material for another issue.

I wonder if a margin of "5" is meant to be 5mm wide. AFAICS the scaling was inconsistent until about 2 minutes ago, though...

The margin could be the one you have used in the document.

I've just assured myself that zero in the variable won't lead to anything drastic. Maybe make this a configuration option, later?

[gunterkoenigsmann]

Will try to add one. Additionally I will make another attempt on getting the print scale right or at least consistent.

[gunterkoenigsmann]

I cannot claim, though,that I have found out what factors affect the print scaling.

In about 20 hours on https://wolfgang.dautermann.at/maxima/nightlybuild/ you can download a windows installer that (hopefully) does exactly what you want. Any testing is welcome!

Hello, I have tried the new version and I get the following error when I try to print. Also, when I want to change the configuration options, the program closes.

That kind of report is very important: I don't own a windows box I can test wxMaxima on - and some problems just don't happen to trigger on Ubuntu. Let's hope that I got it right this time. In about 14 hours the dautermann.at site will contain a (hopefully) corrected wxMaxima version.

About the changes in .cpp and .h files: The files referenced in the commits and yurytch's and my messages refer to changes in the c++ source code of wxMaxima: a more-or-less human-readable description of what the program is supposed to do that is detailled enough that a computer can translate it to a .exe file that actually does do that.

[bllamarodri]

Thank you very much. I will check it again.

Hi, I have checked both versions (32 and 64 bit) and they still give the same problems.

Tomorrow's nightly build (hopefully) greatly enhances the printing experience.
