Re: Any Windows build changes since 6.4.5-3?

The Ruby folks have suggested an alternative using MinGW and MSYS, so I'll investigate that. Thanks for your offer to build a version to my spec. I really don't want to burden you with requests like that, but I'll hold on to your offer in case the MinGW approach fails.

Re: Any Windows build changes since 6.4.5-3?

I'll try it. I also have to be compatible with the pre-built Ruby 1.8.6. I don't know what my constraint will be there. I'll ask on the Ruby Forum. I could also use the most recent IM binary that was built with the older compiler.

Thanks.

Any Windows build changes since 6.4.5-3?

I'm trying to build a new Win32 version of RMagick using the latest Windows binary ImageMagick-6.4.8-6-Q8-windows-dll.exe. When I test using the new RMagick, the test fails with a number of "An application has made an attempt to load the C runtime library incorrectly" messages, and then " no decode ...

Re: 2 questions about -kerning

I'm sorry. I should've added a link. RVG's been around for some years now. It's fairly static.

Follow the "Next" links to see the reference doc.

Re: 2 questions about -kerning

You're correct. For my purposes, the kerning unit is a pixel. However, I'm not so much concerned with drawing using SVG as I am with supporting my Ruby RVG library, which generates MVG code. I've already got a rough-but-adequate implemenation of letter-spacing and word-spacing working but a kerning ...

Re: 2 questions about -kerning

As such my tests seem to indicate it is in pixels . I agree. Well, almost but not quite pixels. I ran some quick tests using a string of 260 alphabetic characters at 3 different densities and 6 pointsizes. Each unit increase in the kerning value increased the average width/character by 1 pixel plus...

2 questions about -kerning

Regarding the new -kerning option. What units are the value? Pixels? Points? English Metric Units?

Also, is there a corresponding -draw primitive?

Re: HSL to RGB conversion slightly different in 6.4.6

Thanks for your offer! However, I don't think you'd get much use from my tests. I've really tried to focus the RMagick tests on validating RMagick, so they only incidentally turn up bugs in ImageMagick. For example, I found this particular problem because I have a test that round-trips the conversio...

HSL to RGB conversion slightly different in 6.4.6

I'm not asserting this is a bug, just that the result is different. This may also indicate that I don't understand how to properly use MagickCore to convert HSL to RGB. The test program converts "hsla(0,48,39,0)" to a MagickPixelPacket, then back to HSL with ConvertRGBToHSL. In 6.4.5-8, the program ...

Encipher/DecipherImage doesn't round-trip in 6.4.6-0

The following program enciphers an image, then deciphers it. In 6.4.5-8, the deciphered image has the same signature as the original image. In 6.4.6-0 the signatures are different. The input image is http://home.nc.rr.com/foxhunter/Flower_Hat.jpg as usual. /* Tim Hunter, cyclists@nc.rr.com gcc `Magi...

Re: Make colors more dark and vivid

Check out the -modulate option. I used -modulate to change your image to something very similar to the one you posted. This command simply reduces the brightness of the input image to 80% of its original value and leaves the saturation and hue unchanged. I'm sure you could come closer with a little ...

Re: enclose jpg in png 'border'

The JPEG format doesn't support transparency. Save the resulting image as a PNG or GIF instead.
