while trying to get the plugintrace.py file to work i fell upon an idea.
Using the export-as-svg.py script i exported a file as a svg and a png (what the script does)
Well after i opened the output svg file in Inkscape i enlarged it ( a 630x475) to 4200x3167
And the resulted PNG file was not deformed. :)

Wow i can't believe i have not used this until now to enlarge images.
Fantastic results.

Excellent! Thanks Rod!

Question: Is this almost like doing the same thing? ----> viewtopic.php?f=22&t=387&start=10

I still see a lot of pixelization when I view your image at maximum rez Rod. I've had some success using Smilla Enlarger. :)

I think because the original was pixelated also at magnification.

Well, I keep looking at both images (one is doubled in size) and they both look the same to me, at 100% resolution. Or am I missing something?

Is O's tutorial the same as doing this, only using svg? The notable difference with this is svg files are incredibly small in file size.

My thought was you have no need to use bitmap trace in Inkscape if you already have the svg outsourced from Gimp.You just need to open it in Inkscape.Then export as PNG at a larger res and dpi.
Just a small shortcut i guess.I just never knew this was possible with this plug-in. :)

Not to be nitpicking, since using the plug-in to enlarge is interesting, I find that leaving the image as a svg gives a better result when opened in GIMP. Note the examples below:

The original png image at 300%:

Image exported as svg, doubled in size, at 200% (300% selection wouldn't fit on my monitor screen):
Image

When exporting the same image (above) back to png (from svg):

I see what you mean.The svg does seem to jaggy more being re saved as a png doesn't it?
Well no need to open in Inkscape then.

Good catch Mahvin! :)

On another note i downloaded and tried the program Lyle mentioned above...pretty cool too. :)
Thanks Lyle.
