convert svg to jpg, rotation artefacts

[fmw42]

try setting the -virtual-pixel to white. see http://www.imagemagick.org/Usage/distorts/affine/


you can also try using -distort SRT to do the transform with rotation and xscale and yscale.

see http://www.imagemagick.org/Usage/distorts/#srt

you can also change the interpolation to have more or less smoothing/antialiasing

and you can control the virtual-pixel setting for the edge interpolation

ImageMagick has two SVG renderer. Type

• identify -list configure

Is rsvg associated with the DELEGATES tag? To use the internal renderer use this command:

• convert msvg:test.svg res.jpg

The conversion worked fine for us (no outline). We're using ImageMagick 6.5.3-7.

Looks like it may be a problem in IM's call of the RSVG library.

Internal MSVG converter works fine

Code: Select all

   convert msvg:t.svg show:

But no attempt at using the rsvg converter from "convert" has worked.

however using the rsvg commands

Code: Select all

  rsvg-convert t.svg > t.png
  convert t.png -background white -flatten show:

also works fine!

Try this command:

• convert -background none svg_img_ex.svg svg_img_ex.png

[anthony]

I tried

Code: Select all

convert -background none svg_img_ex.svg  -background white -flatten show:

And I still get the 'black halo' bug along the edges, that the user is complaining about.
I do not get that using the rsvg-convert command.

Note the image in the SVG is svg_img_ex.gif.jpeg that is a jpeg image.

After converting the JPEG to GIF

Code: Select all

  convert svg_img_ex.gif.jpeg  -matte svg_img_ex.gif

and fixing the image reference link in the SVG
I still get same 'black halo' along edges bug
