Code: Select all
convert -size 100x60 xc:skyblue -fill white -stroke black \ -draw "circle 50,30 40,10" draw_circle.gif
I can certainly see how the starting point of the draw operation is centered at 50,30. When I find the center of the image, it is at 50,30. I can even make quasi- sense of the 40 value being that the left and right edges of the circle are approximately 20 pixels (1/2) left and right, at 20, 70 (if that assumption is even valid).
The number 10 is throwing me. The top edge of the circle is *approximately* at y-axis 10 but that use doesn't make sense to me to have the second parameter (10) be an axis position when the first parameter (40) looks to be an offset value.
Feel to flame my n00bery, tell me to read the manual (which I have), insult my family lineage, etc. but I just don't get it. Explain please? Thanks in advance.
