Hi there,
@Mikko: great post, makes things clear and sharp
@Erik (#28): we got the same problem, we managed to fix this using ImageMagick 6.5.1 with Imagick 3.0.0

Cheers!

Hi Mikko,

I’ve been working on a PHP script to warp images, but it seems like there is a problem with setImageVirtualPixelMethod(). For some reason, it is not applying imagick::VIRTUALPIXELMETHOD_TRANSPARENT. Instead, it defaults to VIRTUALPIXELMETHOD_EDGE, thus extending the pixels on the edge of the image outward to the borders of the actual file. (It even does this with your example above.) I started a thread on imagemagick.org, but everyone is stumped. Might you have any ideas as to how to solve this?

Here’s the thread. http://bit.ly/arszAx

Any help is much appreciated! Cheers!

Hey Mikko! Hey guys!

I am having the same issue with transparency as MrABC & phord. I’m using Windows 6.59 Q 16, Php 5.2.

I’m wondering if anyone figured out what the problem is?

Hey Mikko,

Another great post! I have a challenge for you that would be awesome, but im not even sure if it is possible. How about making a function that turns an image into a sketch and fills parts of it red, white and blue in the same manner of the Obama face images seen everywhere– http://tinyurl.com/y87xcv5. Probably way to complex to do, but i’d though I would ask.

As an experiment to try and get used to the Imagick PHP extension I was trying to convert the IM Watermarking with Text (http://www.imagemagick.org/Usage/annotating/#wmark_text) example but what I’ve been able to accomplish with using Imagick doesn’t exactly match with that the IM CLI produces.

What is better: Imagick or MagickWand? I’ve been looking all over, and I can’t really find an explanation of the differences or advantages of one or the other.

Any input would be appreciated!

Mikko Koppanen;

This is great and can probably help me with a project I have,

do you know if this principle can be applied to convert an equirectangular image to a set of cube faces?

lets say this: http://upload.wikimedia.org/wikipedia/commons/e/ea/Equirectangular-projection.jpg

and extract 6 cube faces like this:
http://i.msdn.microsoft.com/Bb204881.cube_faces(en-us,VS.85).gif

but each cube face saved as a separate file.

I’ve been looking everywhere and I ended up on your great site, so hopefully you can help me

Thanks!
