      Add clause to node query to select just experimental nodes when -e · 807f505a
      Leigh B. Stoller authored
      option was given (as is when called from experiment page). This
      restricts the nodes to just those in the experiment.
      
      This interacts with ghosting mode (where other nodes on other floors
      are shown). In the above case, should ghosting show all nodes on other
      floors, or just nodes in the experiment on other floors? For now, it
      does the latter, but it might useful to have a mode for the other
      case?

      Add MapQuest-style pan and zoom controls to the floormap.php3 page, and · aa7d57a9

      generally improve the clarity and appearance of the maps.  The scale factor
      buttons numbered 1-5 actually correspond to scale factors of 1, 1.5, 2, 2.5,
      and 3.
      
      Notice that the floorimages table in the database now has an integer "scale"
      column to distinguish the cached zoomed-in images with a suffix "-[1-5].jpg" .
      
      I use jpeg files instead of the png files that were used before.  They look as
      good or better, and are a third the size.  Panning around at a given zoom
      factor just involves cropping out a different rectangle of the scaled-up
      images.
      
      The 0311X064_[1-4]fl.pdf floor map files we got from Michael Kay started
      out life in Adobe Illustrator.  Although GhostScript/gv crash while
      trying to draw the pdf files, extracting them into PostScript files in
      Acrobat on Coke allows GhostScript to render them flawlessly.
      
      I started out using gs to render jpeg files in the shell, and then
      found that ImageMagick uses the same GhostScript renderer, and nicely
      handles cropping, drawing and annotations, and format conversion as well.
      
      The PostScript rendering gets slow at higher zoom factors.  So I cache the
      zoomed floor images, scaled up by rendering the PostScript files at a finer
      dot-pitch (density) in GhostScript, and then cropping out the right rectangle
      to register them properly.
      
      For readability, and to avoid having the thin lines and bitmap fonts used in
      some parts of the PostScript map from falling between the pixel cracks, I
      actually render at twice the pixel density and filter down to the final image
      with a gaussian -sharpen option to keep it from looking blurry.
      
      ImageMagick is callable from both the shell and as the Image::Magick package
      in Perl.  I converted the Perl logic in floormap.in to use Image::Magick
      instead of the GD graphics library, resulting in anti-aliased (smoothed)
      drawing of the wireless node dots and labels on floor maps for a better
      appearance.  Then I added optional scaling and centering arguments which
      select the proper cached zoomed-in image, and drive the logic for cropping and
      drawing.
      
      I modified the floormap.php3 file to wrap an input form around a set of zoom
      control buttons and the floormap image.  The zoom buttons set the scale
      argument to the Perl floormap script called on the server.  The floor map
      image itself is wrapped in a graphical submit button, so clicking on it
      returns the mouse coordinates within the image, which are then sent to the
      centering argument of the Perl script.

      Add support so that setnodeloc and floormaps can be used on the · 159ced78

      new_nodes table. Thought it would be easy, but ended up doing more
      damage then I expected; oh well. New nodes show up in "gold" color
      (not listed in the legend).
      
      I added a link from the newnode_edit page. Rob will need to arrange
      for a location_info entry to be created when a new node is made live
      (but only if building/floor are not null).

      Switch everything over to using new buildings and floorimages tables · 315c5d9c
      Leigh B. Stoller authored
      that I added to the DB. See revision 1.251 of sql/database-create.sql.
      I have removed all of the hardwired names of buildings, images, files,
      etc. I have also added MEB floors 1 and 2, but they do not show up on
      the status page unlesss there are actually nodes assigned to them.
      When you go to set a node location, you do see the little thumbs of
      all existing buildings/floors, so you can add nodes to floors that do
      not currently have any.
      
      Still needs some work to cleanly display multiple buildings, but thats
      for another day.

      A bunch of cleanup and improvement. · 7bc9596e
      Leigh B. Stoller authored
      * Redo all the MEB .png files, removing the existing titles from the
        images, and cropping down the images to the actual floors. Redid the
        thumbnail files at the same time. Note that the existing location_info
        entries need to be updated, which I will do.
      
      * Rework portions of floormap.in in preparation for using the DB to
        describe the image files (still hardwired into the floormap).
      
      * Draw a title in each image using a truetype font, based on what will
        eventually come out of the DB, plus a floor tag.
      
      * Add option (-t) to not draw any titles; just naked images.
