I have very poor eyesight.  This happened suddenly in Nov. 2012.  I can barely

Can you PLEASE do that simple thing for me without telling me how dumb I am 
because I can't see?

PLEASE UNSUBSCRIBE ME.  God what kind of person are you?  All I want is off 
your list.  I can't see well enough to read the documentation or plow through 
the web site.

Why don't do this in Inkscape?
You can import an image and use it as backdrop. Then export everything
as jpeg or whatever.
Hope it helps

I may give this a shot.  If I can export as a TGA file from Inkscape, then I'll
definitely be doing it this way.
Thanks!

No, Inkscape exports only png. But if you install imagemagick you can 
convert easily:


convert yourimage.png yourimage.tga

Or import in GIMP and export as TGA.

Hope it helps

Fantastic! Thanks
The only addition is to run perspective tool afterwards to correct side

Very nice!

In similar cases I have used the Perspective Tool in "Corrective
(Backward) mode to square up warped photos-of-photos and documents,
sometimes followed by running Filters > Distorts > Lens Distortion
against all or part of the image.

The Distortion Correction Between Paths plugin adds another useful
tool to the "bent document correction" arsenal; my initial
experiments seem to indicate it will be especially effective with
photos of pages in books and similar geometries.

No, it's rasterized.  You can import SVG as paths if that helps.

Rasterizing is normal behaviour. Opening SVG in GIMP at a high
resolution helps a little.  I don't recommend using GFig, and I don't
think it can do SVG (when it can do anything at all).

Re: [Gimp-user] Batch mode: "batch command experienced an execution error"

[Kevin Payne]

That's the standard error message to tell you the script failed. There is no 
more information available.

Chances are you have a typo in your script - a missing/extra parenthesis .

I recommend you take your problem over to one of the GIMP forums - gimpchat.com 
or gimpforums.com for preference, where you can post your code and get much 
quicker responses and things are so much easier.

You
 mean that in GIMP's vector import dialog you specify a scaling ratio (X
 Ratio / Y Ratio) of 0.50 ?  Then of course you are going to get some aliasing 
(just the same as if you scaled a raster image by 50%), but the overall result 
should closely resemble what the original SVG document looked like . . . at a 
50% zoom level.

Remember that in a vector document "pixels" do not correspond to "on-screen" 
pixels but are a physical unit of measure.

If you are taking the 2048x2048 image and scaling it to 80x50 then that is a 
ratio of less than 10 percent and of course the result is probably going to 
look like a blurred/aliased mess of pixels.  Now if the original SVG document 
itself had a document size of 80x50 (which is separate from the size of vector 
elements in it) then GIMP should be able to import it fine.

[Gimp-user] aliasing in vector images

[sonicbluegt]

Thanks for the reply Steve!

I think maybe my problem wasn't communicated from my end correctly.

I have an SVG file generated with a native resolution of 2048x2048 in Vector
Magic.  In Inkscape, I can resize the image to be 1024x1024, zoom in, and it
"redraws" the image with no aliasing (as a vector should).

However, when I do the same in GIMP, it aliases, as though it's no longer a
vector and is drawn as a raster image instead.  I understand that GIMP is
raster-based.  I guess I was just thinking that when it "opens" a vector image,
that it's still in vector format instead of being rasterized.

The biggest red flag that led me to believe something wasn't working correctly
was when opening a vector in GIMP at a size of about 80x50 and all it produced
was an unrecognizable blob of pixels.  I feel as though I've been able to do
this in the past and it would produce a smooth image without aliasing.

What I'm trying to do is overlay a design onto another image without aliasing. 
What I'm ending up with, though, is no better (actually might be worse) than
just drawing the image in GIMP instead of importing a vectored  version of the
same graphic.

Is it possible I'm missing a plugin or something since I updated GIMP?  Would
installing Ghostscript or GFig on my machine solve my problem?  Or is it
possible that nothings wrong and I'm trying to do something that's just not
capable?
