Re: svg loading ignores -density

“I don't fully understand the relationship between these methods.”

Me neither, and there's some pretty weird examples on MDN (eg. width="150", height="100", viewbox="0 0 3 2"). RSVG loads that one as 150×100.

Anyway for now I can solve my problem by using inches. Thanks for looking into this.

Re: svg loading ignores -density

I can confirm that this still works if you specify the width and height in length units. So as a workaround I can specify inches as size, assuming 90 px/inch. I don't think specifying the size (or other content) in pixels is an error though. Examples on MDN specify sizes in pixels [1]. Inkscape will...

Re: svg loading ignores -density

RSVG is one of the built-in coders, it's installed with ImageMagick. My guess is that it's embedded in IM_MOD_RL_svg_.dll . How would I call this directly? Right now on this PC this is working with version 6.9.3-3 and not working with version 6.9.8-0, so it would be a regression somewhere between th...

I still have to find the original issue though. Some more tests on this other PC: >convert -verbose -density 300 test.svg test.png test.svg SVG 333x333 333x333+0+0 16-bit sRGB 202B 0.016u 0:00.006 test.svg=>test.png SVG 333x333 333x333+0+0 16-bit sRGB 193c 7.86KB 0.031u 0:00.014 Note the resolutions...

Re: svg loading ignores -density

Just tested that, Inkscape responds to the DPI argument. I have v0.91 as well. Given this command line the PNG file will be half the size: >inkscape.exe test.svg --export-dpi="45,45" --export-png=test.png But ImageMagick is calling inkscape with the --export-eps option rather than the --export-png o...

That's not the case here: >convert -density 300 -verbose test.svg test.png test.svg SVG 100x100 100x100+0+0 16-bit sRGB 229B 0.016u 0:00.022 test.svg=>test.png SVG 100x100 100x100+0+0 8-bit sRGB 100c 1.68KB 0.016u 0:00.030 I can enable Inkscape in the delegates.xml file: >convert -density 300 -verbo...

Hi, I'm trying to convert a SVG file to PNG or JPG, but I'm trying to load with a different resolution than the default. test.svg <?xml version="1.0" encoding="UTF-8" standalone="no"?> <svg width="100" height="100"> <circle r="29" cy="38" cx="36" style="opacity:.5" /> <circle r="29" cy="63" cx="66" ...

Re: Python can't register CORE_RL_wand_.dll

Well, I partially figured this out. You have to change the working directory to the ImageMagick installation directory. And more annoyingly, if your python script changes the working directory afterwards, then some images will fail to load because the coder DLL can't be loaded. I verified MAGICK_HOM...

Re: Python can't register CORE_RL_wand_.dll

No I didn't have the Visual C++ 2013 Redistributable installed, but installing it didn't make a difference.

Note that:
  • msvcp120.dll is included in the installation
  • ImageMagick itself (convert, etc) runs fine without having the Visual C++ 2013 Redistributable Package installed.

Re: [patch] Support writing EXR files with different color types

OK, so this is the list of color types supported. I'm not sure how to put this in the documentation. RGB: RGB colors RGBA: RGB with alpha channel YC: Write a brightness channel (Y) and two chromaticy channels, defined as R/Y and B/Y. The two chromaticy channels are subsampled by a factor 2x2.

[patch] Support writing EXR files with different color types

EXR allows writing files using 2x2 color subsampling (aka 4:2:0). You can find a reference to this on the old release notes at http://www.openexr.com/: OpenEXR now supports high dynamic-range YCA (luminance/chroma/alpha) images with subsampled chroma channels. These files are supported via the RGBA ...

Re: How to Build ImageMagick-6.8.8 or ImageMagick-6.9.1 sources on Visual Studio 2012

When I compiled ImageMagick 6.9.0 there were also two scripts, called UpgradeToVS2010.cmd and UpgradeToVS2012.cmd . I had to run the correct one before opening the solution file or it wouldn't work. In version 6.9.1 the Configure Wizard has a dropdown to select the version of Visual Studio to use. A...
