high rez photo trace

Postby LT72884 » Mon Jan 06, 2014 10:26 am

Ello all. I have a question about features. I hope someone here has illustrator and inkscape and can help a novice like me answer a question. This is about high rez photos.

First question. In illustrator, once you have imported a high fidelity pic, you can go under thr trace tab and select high fidelity photo and it will trace it and turn it to a vector and it looks almost 100% like the original.

This seems impossible in inkscape. How can high rez photos be traced in inkscape without looking cartoony?

Second question, is there a need to convert such large high rez images to vectors? What if i wanted to make a picture to hang on a building? Would i need a vector or raster? Are billboard photos raster or vector?

Thanks

Hi.

Large format prints aren't always dealing with regular image resolutions, thus vector format is not a necessity.
You aren't looking at a billboard from the distance you would read a book.

504 cm/238 cm is a regular billboard format.
On an offest printing machine that size would look fine at even @ 30 DPI, CMYK.
That is, 5953 px/ 2811 px.

Digital prints can have larger resolutions, so it all comes down to your needs.

Hmm interesting. Ok, so now that question two is answered, how does inkscape compare to illustrator in the arena of high fidelity photos to be traced? I dont know why i want to vectorize a hi fi photo.....

Thanks

I don't own Illustrator, but the Google-machine tells me AI has a well developed mesh gradient feature, which is still in the oven for Inkscape... I've no idea regarding integration of it with the trace feature.
Have a nice day.

I'm using Inkscape 0.92.2 (5c3e80d, 2017-08-06), 64 bit win8.1

The Inkscape manual has lots of helpful info! http://tavmjong.free.fr/INKSCAPE/MANUAL/html/

Hmm, ok cool. I do like inkscape alot. I have asked a graphic designer friend who uses AI and he asked me why i would need to make a hi rez photo a vector. He says if the photo is high rez, its going to be pretty large in physical size, large enough for 99% of graphic work out there. Haha.

So i guess im beating a dead horse sorta speak. Thanks
