If you installed the new version using the default PREFIX, then it's in /usr/local/bin. I don't know where yum installs things. Probably /usr. Anyway, find out the directory in which the old ImageMagick is installed, and then make sure that /usr/local/bin precedes that directory in your PATH. If you ...

I see DrawSetOpacity in 6.5.5-5 and now I have a question. I'm confused about the difference between opacity and fill-opacity so I looked at magick/draw.c. I see that opacity changes the fill opacity as well as the stroke opacity and fill-opacity changes only the fill opacity. However it appears ...

We're both right. I guess your test uses the opacity primitive. Since I'm using the MagickWand API, my test uses fill-opacity . The fill-opacity primitive does not produce the desired result.

Here are two versions of the same test. This was created using the DrawSetFillOpacity in the MagickWand API ...

Should I be seeing the fix in 6.5.5-2? My test still demonstrates the problem.

Thanks!

Apparently I was not clear about the difference I am questioning. In the ImageMagick output the pair of red & green circles 2nd from the left on the bottom row look like they're entirely opaque, but in the SVG example they are .5 opaque.

Per your advice I downloaded the SVG example and converted it ...

I'm trying to reproduce this example from the SVG spec ( http://www.w3.org/TR/SVG11/masking.html ) but I see a discrepency. Notice the 2nd pair of circles from the left on the bottom.

I believe this MVG script is the equivalent of the SVG ...

Thanks for both fixes!

Here's a simplified version of the skew y problem. Notice that the Y-axis is skewed 60 degrees instead of 30.

This is ImageMagick 6.5.4-8 on Ubuntu.

How do I set the border color to be used with DrawColor and the FillToBorderMethod? In MagickCore I'd just set the border_color member in the DrawInfo structure.

You're welcome!

Download and unroll the ImageMagick tarball. Change to the ImageMagick-6.5.4-3 (or whatever the version is) directory and run the configure script using the same options you used when you installed it. Then run
.
