I assume this post isn't getting much attention as this type of bug is complex to diagnose?

If so, I understand. Just wanted to make sure it wasn't something else, like "that doesn't look like a bug".

Here's the lines image when drawn with IM 6.7.7 instead of 6.9.0 command: convert -size 220x220 xc:black -draw "fill none stroke-linecap round stroke-width 4 stroke green stroke-dasharray 1,10 line 10,10 200,10 line 10,100 200,100 line 10,120 200,120 stroke red line 10,128 200,128 line 10,180 200 ...

I'm having an issue with drawing lines, arcs, rectangles, with dotted lines. I have tried different versions of imagemagick, back to 6.7.7, and while the bug works a little differently, it appears in older versions as well. The only difference is at what point the round linecaps quit being drawn ...

Terrific! Thanks....that gives me something to play with.

Okay...seems nobody has anything easy.

I ...

Two '-flip' operators would work then. Flip the image first, delete the original, then flip each generated tile.

EDIT: Oh, yes. -flop, not -flip Works a treat as far as I can tell. Not sure why you don't like it

If it's always going to be a 3x3 tile, -swap can reorder the images:

-swap 0,2 -swap 3,5 -swap 6,8

should work for your 3x3 grid.

I'm trying to overlay two images, top to bottom, but with some overlap of the transparent areas. Image #1: convert -background none -fill red -font Arial -pointsize 72 label:Jimmy\'s one.png http://www.brightledsigns.com/images/test/one.png Image #2: convert -background none -fill blue -font Courier ...

Hello, I see that the command line version of ImageMagick allows for two ways to have text follow a curve when using "convert -annotate" #1: http://www.imagemagick.org/Usage/fonts/#arch #2: http://www.imagemagick.org/Usage/fonts/#arc I've tried various incantations with the perl API, and can't seem ...
