exporting highcharts polar chart to PDF with phantomjs -


i'm evaluating highcharts client project , have run problem rendering polar chart phantomjs. charts lines come out thick grey blob! thought due animation thats turned off. try , post image have thoughts on else causing this? if print preview chrome looks ok.

here's image.

this created part of report built using rasterize.js script included phantomjs. other charts work fine, polar chart 1 not coming out. if use highcharts export server script phantomjs works fine - allows 1 chart exported pdf. need export whole web page pdf including charts.

there's workaround on project's bug tracking:

https://github.com/ariya/phantomjs/issues/10364#issuecomment-14992612

all need remove page elements low opacity before rendering file:

diff --git a/examples/rasterize.js b/examples/rasterize.js index fcd74cd..dcc81d4 100644 --- a/examples/rasterize.js +++ b/examples/rasterize.js @@ -19,6 +19,16 @@ if (phantom.args.length < 2 || phantom.args.length > 3) {              console.log('unable load address!');          } else {              window.settimeout(function () { +                // remove low-opacity paths. see phantomjs  issue #364  +                page.evaluate(function () { +                    var paths = document.getelementsbytagname("path"); +                    (var = paths.length - 1; >= 0; i--) { +                        var path = paths[i]; +                        var strokeopacity = path.getattribute('stroke-opacity'); +                        if (strokeopacity != null && strokeopacity < 0.2) +                            path.parentnode.removechild(path); +                    } +                });                  page.render(output);                  phantom.exit();              }, 200);

you can use grab graphs if don't have access source of page containing graph.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
