Flowing text in inkscape (Poster making)

You can flow text into arbitrary shapes in inkscape. (From a hint here).

You simply create a text box, type your text into it, create a frame with some drawing tool, select both the text box and the frame (click and shift) and then go to text->flow into frame.


The omnipresent anonymous asked:
Trying to enter sentence so that text forms the number three...any ideas?

The solution:
  • Type '3' using the text tool
  • Convert to path using object->path
  • Size as necessary
  • Remove fill
  • Ungroup
  • Type in actual text in new text box
  • Select the text and the '3' path
  • Flow the text

    mencoder input.mp4 -speed 0.33 -vf scale=450:360 -ovc lavc -ffourcc DX50 -oac pcm -o output_slowmo_small.avi

    The -ffourcc DX50 makes it quicktime playable
    The pcm is needed when we change speed (copy won't work)

    TimeTracker - see what files Time Machine is backing up

    1.9GB backup! Since yesterday? I work hard, but not that hard. I wanted to see what exactly was getting backed up. Time Machine doesn't let you do that but TimeTracker from CharlesSoft allows you to peek into your Time Machine backups and see what is getting backed up for each backup and how big it is. For instance, its annoying but my email trash is getting backed up. It would, however, take too much time to go through and find every little think that I don't want backed up but is getting backed up, so...

    Mac OS X time machine: deleting backups

    From here:
    You can delete specific folders and files from the backups, deleting all backups if needed. Open a finder window, navigate to the folder, open time machine, click the gear icon and select 'Delet backup'. If you are in the tree view you have an option to delete all backups of the selected folder.

    qmake redux

    In QT 4.6 qmake's default behavior has changed. If you just run qmake it will generate an xcode project. You now need to do

    Inkscape, Mac OS X and X11

    X11 latest version (XQuartz 2.4) copies stuff as a bitmap by default. Switch that off in the preferences to copy vector graphics.

    ALT key won't work, preventing us from doing super script and subscript (kerning with ALT+up or down arrow keys)

    ALT key can be made to work like this or this (but I was not successful)

    Sizing for posters, talks and papers

    Following society for neuroscience guidelines for figures:
    Text on figures should be 2-6mm high -> 5.6pt to 17pt
    Using figure labeling to be at least 8pt Arial for papers = 2.8mm
    Use a scaling of x2 for talks = 5.6mm
    Use a scaling of x4 for posters =  11.3mm
