i don't know if lib supports such thing. can check image meets size limit , keep untouched in case does.

- $image->resize($width,$height); - $image->save("images/gifts/".$_files['uploadedfile']['name'], $type); - unlink($_files['uploadedfile']['tmp_name']);  + if ($image->getwidth() == $width && $image->getheight() == $height) +     move_uploaded_file($_files['uploadedfile']['tmp_name'], "images/gifts/".$_files['uploadedfile']['name']); + else + { +     $image->resize($width,$height); +     $image->save("images/gifts/".$_files['uploadedfile']['name'], $type); +     unlink($_files['uploadedfile']['tmp_name']); + }

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
