This page is intended to give some examples what Meteobridges weather image conversion with the Linux tool convert can offer. I selected this freely available image from Univerity of Arizona as an example to do some comversions with.
Contents
original image (720 x 540)
cut off header, new size (720x490)
Overlay text:
-crop 720x490+0+50
adding weather data as overlay text
Overlay text:
-fill black -draw "fill-opacity 0.7 rectangle 0 520 720 540" -pointsize 12 -fill orange -draw "text 5 535 '[YYYY]-[MM]-[DD] [hh]:[mm]'" -fill white -draw "text 110 535 'Temp: [th0temp-act=F.1:--] °F Humidity: [th0hum-act.0:--] % Pressure: [thb0seapress-act=inhg.2:--] inHg Wind Chill: [wind0chill-act=F.1:--]°F Wind: [wind0avgwind-act=mph.1:--] mph Rain: [rain0total-sumday=in.2:--] in'" -crop 720x490+0+50
resize image to 640 x 480 (ignore aspect ratio)
Overlay text:
-fill black -draw "fill-opacity 0.7 rectangle 0 520 720 540" -pointsize 12 -fill orange -draw "text 5 535 '[YYYY]-[MM]-[DD] [hh]:[mm]'" -fill white -draw "text 110 535 'Temp: [th0temp-act=F.1:--] °F Humidity: [th0hum-act.0:--] % Pressure: [thb0seapress-act=inhg.2:--] inHg Wind Chill: [wind0chill-act=F.1:--]°F Wind: [wind0avgwind-act=mph.1:--] mph Rain: [rain0total-sumday=in.2:--] in'" -crop 720x490+0+50 -resize 640x480!
