Re: [Therion] FW: Scalebar metapost labelling errors

Hi Thomas

change the line to

tmpx:=tmpl * (i * 2 / l - 1);

works for me up to 1:30000

Thanks! Same formula rearranged does the trick! This line of metapost does work better. The scale and scale-bar statements within the layouts work together. If the physical length of the plotted scale bar is too short or too long at the chosen scale then an error is produced (Therion reports as CP-02). With scale bar statements between 100m and 1000m in length it will work with scales approx 1:150 to 1:30000. That's plotted scalebars on the output between 35mm and 650mm long. Seems a reasonable tolerance. Bruce
