I get...


...when running 'make' on the 1.0.9 version. 1.0.8 compiles just fine using the same install steps as outlined on http://www.magickwand.org/

What might I be able to do to overcome this missing reference?

Thanks.

Hahahaha! Ok... So it was a version compatibility issue I guess. I had to upgrade from MagickWand 1.0.6 to 1.0.8 and ImageMagick from 6.5.0 to 6.5.1 I'm still puzzled on how a function who's syntax has remained unchanged could be effected by minor version updates. Nonetheless, my problem is solved!

It may help to have a more succinct example. Here's the original image: http://img220.imageshack.us/img220/7190/awesomex.png The convert command I'm trying to emulate is: convert awesome.png -matte -background none -rotate 30 rotate_trans.png ... and it's output is: http://img87.imageshack.us/img87 ...

Code that used to be working is no longer probably due to an upgrade of ImageMagick. I think.... I've have code to rotate PNG alpha transparency images. Where it used to correctly leave the excess 'new' areas transparent, it now leaves them as solid black. This picture would be the best example. I'm ...

My best solution seems too involved. But, here it is:

Load image $a
Create copy $b
Fill $a with new color (MW_ResetMethod)
Separate alpha mask from $b
Invert $b
Composite $b on to $a (MW_CopyOpacityCompositeOp)
Save a$

I believe IE ignores the framerate values per frame that every other browser and image program do pay attention to.

I see the +level-colors flag was added to convert about a week after the latest version of MagickWand. I really need this functionality in MW. Does anyone know if there is an equivalent function in MW? What I'm trying to do is take a PNG with some plain white text on it and a mask around that text ...

I think that question lies outside the realm of this support board. I'll say that I think you need to pay attention to the use of this montage. Do they need to be generated live? Could you pre-render a bunch and just have them handy for a user's http request? Basically, the idea is, why have the ...

I needed to add...
Before my MagickEvaluateImage() function.

wait, I'm replying to the wrong thread....

I'm trying to convert a JPG to a PNG and add an alpha mask. Here's the code I have currently. My script dies during MagickSetImageAlphaChannel and error_reporting(E_ALL) doesn't say why. MagickSetImageFormat($wnd, "PNG32"); error_log("MagickSetImageFormat", 0); MagickSetImageAlphaChannel($wnd, MW ...

When there's a will, there's a way. I've discovered that I can set the opacity of my top layer image with the following syntax:

The equivalent MagickWand PHP syntax is the following

I answered my first problem. I had to add the following code... ZEND_FE( magicksetimageopacity, NULL ) right before ZEND_FE( magicksetimageoption, NULL ) in magickwand.c I recompiled MagickWand and it seems to work now. I'm still interested in my followup question about the 'missing' argument value ...

My followup question, To me it seems MagickCompositeImage should have an 'argument' variable. Why doesn't it, or how can I set one? I basically want to accomplish the example here: http://www.imagemagick.org/Usage/compose/#dissolve
