Re: Problems with magickwand examples in branch 6.7
I tried the affine example and it does indeed produce the leaky pixels. It also slightly reduces the size of the wizard and the colours are darker in all four images. I'm using IM 6.7.5 Q16. I'll try the other example when I get around to installing the latest IM. @magick if you want to try it, the ...

Re: How to use distort function of ImageMagick.?
My MagickWand examples in C (link is below in my sig) has examples of using MagickDistortImage in the affine transformation example and in the text effects example. It isn't C++ but it should help you with the arguments for the distort method.

Re: Small memory leaks when resizing gifs with MagickWand
The only thing I can suggest is to try replacing each occurrence of ClearMagickWand(w) with
DestroyMagickWand(w);
w = NewMagickWand();
to see if it makes any difference.
Pete
DestroyMagickWand(w);
w = NewMagickWand();
to see if it makes any difference.

Re: adding alpha channel
This is a fragment of some code I wrote in C which uses MagickWand. It creates a blank 6000x1000 image and then turns on the alpha channel. Perhaps you can find the equivalent of MagickSetImageAlphaChannel in Magick++. mw = NewMagickWand(); MagickSetSize(mw,6000,1000); MagickReadImage(mw,"xc:no...

Re: Detect corrupt images with the C API
I tried your code in 6.7.5-10 and it reads the jpg without throwing an exception. Both Firefox and Paint Shop Pro X4 open the JPG without complaint. However, they don't display exactly the same image. OTOH, Corel Instant Viewer also opens the image but then hangs. Does, perhaps, the JPG standard hav...

Re: How to find text length in pixels?
The MagickQueryFontMetrics(mw, dw, text) function returns metric information for the given text string from which you can compute where the strings should be placed.
See my fontmetrics example.

Re: Distort ARC MagickWand PHP
Have a look at my "Eight text effects in one function" in http://members.shaw.ca/el.supremo/MagickWand/. The third effect uses arc distortion. It's in C, but it should be easy convert to PHP.

Re: [Newbie] MagickWand, ClipPath and dynamic image...
Thanks for the reference Anthony.
Unfortunately, the only example I have uses a clip mask not a clip path.
There is a program called drawtest.c in the MagickWand directory of the svn code which sets a clipping path but I haven't tried it out yet to see how it works.

I've converted a couple of jp2 files to png without any errors. Can you post a link to one of the jp2 files which fails?
