I am sorry, but I know nothing about using IM with the PHP API. With regard to adding images to a background, see the following recent post with Anthony's excellent solution for adding multiple images to a black background. Just chance black to the work "none". Then use different images in...

You probably need to escape the ^ character in windows. I think it might be % but you would need to check.

Using IM 6.4.1-8 Q16 HDRI on Mac OSX Tiger convert -size 100x100 gradient: -colorize 100,0,0 tmp.png or convert -size 100x100 gradient: -colorize 100%,0%,0% tmp.png Produces a cyan gradient rather than the expected red gradient. Seems like colors are being complemented. convert -size 100x100 gradien...

I am not sure why you are having trouble with Anthony's method. What version of IM are you using? Type the following: identify -version If your IM is too old, perhaps you do not have -layers. However, if you do, you can do the following: convert \( -size 475x873 xc:black \) \( cone.png -resize 30x30...

strangely, a while back I did some quick timings and also found that the clone method was faster than the mpr method

Anthony - that is a neat approach!!!

please report back as I for one am interested in your results to see if they agree with what I had found in an old timing example between using clone and mpr. I did not time my last method using mpc.

read http://www.imagemagick.org/Usage/anim_opt/ thoroughly as there other kinds of optimizations and ways of improving quality and speed.

Also search the internet for non-IM programs for optimizing gif animations.

All I can say is try my example. It works for me. The only other issue might be your use of paths to your files. Either move them all the same directory or try absolute paths from root. See also my additional method using memory mapped disk files. More complicated, but you can loop. But first get yo...

try the following for a fixed number of composites convert stamp_pic.png black_canvas.png \ \( -clone 1 -clone 0 -compose screen -geometry +100+100 -composite \) -delete 1 \ \( -clone 1 -clone 0 -compose screen -geometry +200+200 -composite \) -delete 1 \ \( -clone 1 -clone 0 -compose screen -geomet...

Have you reviewed http://www.imagemagick.org/Usage/anim_opt/

For consideration and discussion (although these are more specific suggestions than Anthony's more architecturally suggested changes): 1 ) compiled fx expressions (or whatever it takes to speed up fx dramatically) 2 ) more than one constant allowed in -evaluate so that slightly more complex expressi...

That's great start. It's more of an isometric image, it's missing the 3d perspective. http://www.math.utah.edu/~treiberg/Perspect/PerCube.GIF IM can do perspective, but you still need to create each image properly and composite them so as to form your cube. IM does not have any function at this tim...

Let me start this again as I forgot that hue needs to be expressed in degrees. Consider: hue=cyan=180deg, saturation=50% and lightness=50% convert -size 1x1 xc:" hsl(180,50%,50% )" txt:- # ImageMagick pixel enumeration: 1,1,65535,hsl 0,0: (16384,49151,49151) #4000BFFFBFFF hsl(25%,75%,75%)...

Bonzo,

Following your link, on the page that comes up, the link http://www.rubble.info/gallery/gallery.php requires the user to log-in. Would like to see your working example.

Sorry I missed the part about anti-aliasing. GIF does not support full 8-bit anti-aliasing. It will take a gradient alpha and make it 50% on and 50% off. see http://www.imagemagick.org/Usage/formats/#boolean_trans I am not sure this will work, but you might try flattening the alpha into the png to &...
