Can I enlarge without losing the resolution of the picture?
Hello

I am new to the forums and relatively new to GIMP! Lest May/June, I started with GIMP.....I use it for only free hand drawing using the brush.

Here is one of my drawing - I tried to draw my maltese dog Big Grin
[Image: SnuwyToonByKatkoota.jpg]

The template's original size that I choose (when opening a new white page/window to start drawing in GIMP) is 800 x 600

My question is, can I enlarge my final drawing without losing the quality of the picture (resolution for example)? How can I do that?

Another thing, if I decide to print my drawings on mugs/t-shirts ...etc , any idea what size (picture size) is best for better quality result (on the mug, T-shirt...etc)?

I will really appreciate your input. Thank you!

Kat

Given that your drawing has very few colors (and they seem to be uniform), your best bet is to transform it into a vector image (SVG), that can be resized at will. Gimp can load an SVG and will resize it to your liking. You can then do further editing, but can only save as a bitmap. True vector editing requires a different software, such as Inkscape.

You can transform your image into a vector graphic online on this site: http://vectormagic.com/home or download their free trial version.

Thank you so much!
So after I draw in GIMP, I first save it as .jpg ? (my current drawing is saved as .jpg) Then I transform it to SVG online, in the link that you provided. Then I open it in GIMP to resize it (by doing so, it won't affect the quality). I don't wanna do further editing other than the resizing. Will I still need Inkscape?

Not quite.

The best way to save these drawings from Gimp is the PNG format, that doesn't cause quality loss or artifacts and is very good at compressing large monochrome chunks. JPG is a close second though.

Once you have transformed the drawing to SVG, it is better to keep it SVG, because you won't have to worry about the size in pixels and the printer DPI and such. Direct SVG-to-print will produce cleaner results. SVG capable software (InkScape or else) will handle that for you.
