SVG page boundaries

I made an SVG image in Inkscape, and it has some objects outside the page boundaries, and I want to convert it to PNG.

I don't want the stuff outside the page boundaries to be in the resulting PNG. How do I do this?

I tried this, but it included the stuff outside the page boundaries:

Code: Select all

convert foo.svg foo.png

Code: Select all

$ convert --version

You normally won't get stuff outside the page (or "viewport") boundary.

What version of IM are you using? [EDIT: just seen: 6.8.9-8. An upgrade might help.] What is rendering the SVG? (Inkscape, I hope.)

Most importantly, what is in your SVG? Paste it here, between [ code ] and [ /code ] .

  • How do I tell what imagemagick is using to render?
  • I made the SVG in Inkscape
  • This isn't the image I was using, but it has the same problem for me: ("imagemagick file.svg file.png" produces a 65x18 PNG that contains both the red and green circles, instead of a 60x60 png containing only the green circle with some empty space around it)

When Inkscape is your renderer, the command ...

Code: Select all

convert svgPage.svg s.png
... should say something like ...

Code: Select all

"inkscape" "C:/Users/Alan/AppData/Local/Temp/magick-1904JlPas75xflNB" --export-p
ng="C:/Users/Alan/AppData/Local/Temp/magick-1904CakC_EfLzr7Z" --export-dpi="90,9
0" --export-background="rgb(100%,100%,100%)" --export-background-opacity="1" > "
C:/Users/Alan/AppData/Local/Temp/magick-1904QGyhjzkpc4k9" 2>&1
svgPage.svg SVG 60x60 60x60+0+0 16-bit sRGB 2.96KB 0.016u 0:00.718
svgPage.svg=>s.png SVG 60x60 60x60+0+0 16-bit sRGB 69c 1.14KB 0.000u 0:00.000
... with no errors.

For your SVG, I get 60x60 pixels, green circle on white background, no red circle.

This is with IM v6.9.0-0 and Inkscape v0.91.

I suggest you upgrade IM, or Inkscape, or both.

For me, it doesn't say anything.

I assume that means it isn't using Inkscape?

EDIT:

Code: Select all

$ inkscape --version
Inkscape 0.48.3.1 r9886 (Jan 29 2013)
EDIT 2: Just updated Inkscape:

Code: Select all

$ inkscape --version
Inkscape 0.91 r (Jan 30 2015)
This doesn't seem to have solved the problem.

EDIT 3:

Code: Select all

$ convert SVG-canvas-test.svg -verbose SVG-canvas-test.png
SVG-canvas-test.svg=>SVG-canvas-test.png PNG 65x18 65x18+0+0 8-bit sRGB 66c 3.23KB 0.000u 0:00.009
EDIT 4:

Code: Select all

$ convert -list format | grep SVG
     MSVG  rw+   ImageMagick's own SVG internal renderer
      SVG  rw+   Scalable Vector Graphics (XML 2.7.8)
     SVGZ  rw+   Compressed Scalable Vector Graphics (XML 2.7.8)
EDIT 5: Okay, this is weird:

Code: Select all

$ convert -list delegate | grep svg
        cdr =>          "uniconvertor" "%i" "%o.svg"; mv "%o.svg" "%o"
        cgm =>          "uniconvertor" "%i" "%o.svg"; mv "%o.svg" "%o"
        dot =>          "dot" -Tsvg "%i" -o "%o"
        dxf =>          "uniconvertor" "%i" "%o.svg"; mv "%o.svg" "%o"
        fig =>          "uniconvertor" "%i" "%o.svg"; mv "%o.svg" "%o"
        svg =>          "rsvg-convert" -o "%o" "%i"
This works as expected, producing the 60x60 with a green dot:

Code: Select all

rsvg-convert -o SVG-canvas-test.png SVG-canvas-test.svg
This still doesn't work right, producing both dots:

Code: Select all

$ convert SVG-canvas-test.svg -verbose SVG-canvas-test.png 
SVG-canvas-test.svg=>SVG-canvas-test.png PNG 65x18 65x18+0+0 8-bit sRGB 66c 3.23KB 0.000u 0:00.000

You need "-verbose" before reading the SVG. If you don't turn it on until after you read it, you get no information about how it has read it.

Apparently it is using inkscape.

That's better. We see IM is telling Inkscape to export to EPS, so IM then calls Ghostscript. This crazy behaviour was corrected (I remember reporting it) before v6.9.0-0. I suggest you upgrade IM.

Upgrading imagemagick seems to have solved that problem.

EDIT: How do I mark this solved?
