When giving the 6-element affine matrix in PerlMagick, the last element is not read, making ty=0 in all cases. I think each of the comparisons of length below should be decreased by one. I have 6.3.2-2 at the moment. if (av_len(av) >= 1) draw_info->affine.sx=(double) SvNV(*(av_fetch(av,0,0))); if (a...

Bilinear in contrast just averages out all the pixel colors in the very center of the inter-pixel space, whcih sort of 'blurs' a 'hash' or 'dither pattern' in images. Right, an average weighted by the areas produced when a transformed pixel cuts the original grid of pixels. It strikes me as being t...

X- and y-shears look perfect. I should have said this modulo interpolation. With very stretchy shears, the interpolation has a lot to do with the results, obviously. The "perfect" aspect only meant with regard to positions of the (centers of the) transformed pixels, my particular first co...

I have installed ImageMagick-6.3.2-1-Q8-windows-dll.exe, and I still get excessive logging. Is there a way to turn off logging? Just wondering, is it possible you still have the older PerlMagick with that? I'm not sure what your setup might be like, but I have once or twice built a new version of t...

The best test would be to try a null transform to make sure it comes out right. With the default interpolation (bilinear), the null (identity) transform comes out exactly correct. So do flips and flops and 90-degree rotations, all a good sign. X- and y-shears look perfect. Pure scaling also looks g...

We'll add -fill-pattern and -stroke-pattern to the command line in the next point release. Cool. Is -fill-pattern synonymous with -tile ? And how does the -origin setting fit inhere? I can imagine situations where an independent origin for strokes and fills is desirable. On a commandline it makes s...

How about the command line?

See what I mean?

In the mean time I have downloaded and built the latest SRC RPM from the alpha area, and ran it through all IM Examples. I can now say that Affine Transformations has passed ALL my tests. Which version is that? I grabbed a beta yesterday (6.3.2-1) and don't want to rebuild if I don't need to. The o...

I asked about it in the Users forum, http://redux.imagemagick.org/discourse-server/viewtopic.php?p=25356 but maybe it is better here: There is code in draw_private.h, in the function GetStrokeColor, that allows for strokes to be filled with a pattern, just as are fills. Is this not yet implemented i...

• free(mime);

to

• mime=(char *) RelinquishMagickMemory(mime);

That does it - thanks.

Can you generate a stack trace for us? We tried to reproduce the problem but MagickToMime() works for us. I should have mentioned that this is on Windows, compiled with VC++7 from ImageMagick-6.3.2-1-windows.zip (Beta); perl, v5.8.8 built for MSWin32-x86-multi-thread. I executed the following scrip...

No troubles (of that sort) with the 6.3.2-1 Beta, though.

The PerlMagick MagickToMime method crashes, at least in the 6.3.2 Beta I grabbed yesterday.

I freed my version of the offending free() call at line 5200 in Magick.xs and mine/mime now seems well.

I am trying to create a text with a gradient stroke. Can that actually be done? There is actually code in ImageMagick that lets the stroke come from any image or pattern, just as -tile can be used with fills. (Check out instances of draw_info->stroke_pattern, esp. in the file draw_private.h, at lea...
