Hi!

I run this command in php to create a rectangular shape and with yellow and blue color.

-stroke yellow -draw "stroke-dasharray 5 3 stroke-dashoffset 7.5 stroke-width 1.5 rectangle 12.5,12.5 362.5,212.5" -stroke blue -draw "stroke-dasharray 5 3 stroke-dashoffset 7.5 stroke-width 0.25 rectangle 12.5,12.5 362.5,212.5"

But when output image generated it seems that some the color of the rectangle is different from the color I assigned in the codes.

Is a float number for the points of the rectangle affects the color?

Any help will be highly appreciated.

Thank you.

If you save as JPEG then the colors will never be exact!

Also anti-aliasing pixels may produce mixed colors.

I can't really tell as when I try the above example on a test image I don't see a useful result. Your stroke-width may be too small.

When I adjusted I noticed you draw yellow then overlay it completely with blue!
so no yellow appears in the output...

Code: Select all

 convert logo: -stroke yellow -strokewidth 3 -draw "stroke-dasharray 5 3 stroke-dashoffset 7.5 rectangle 12.5,12.5 362.5,212.5" -stroke blue -draw "stroke-dasharray 5 3 stroke-dashoffset 7.5 rectangle 12.5,12.5 362.5,212.5" show:

On the other hand.....

Code: Select all

convert logo: -stroke yellow -strokewidth 3 -draw "rectangle 12.5,12.5 362.5,212.5" -stroke blue -draw "stroke-dasharray 5 3 stroke-dashoffset 7.5 rectangle 12.5,12.5 362.5,212.5" show:

should have draw a yellow border, then overlaied a blue dashes, and it didn't.

And that is a bug!!!!
