Scaling an image, how without distortion?

4176 Views 10 Replies 5 Participants Last post by  Clinton
I have photoshop elements 4, paint shop pro 9 and gimp 2. I can purchase any other software I need but I need to solve this problem.

I get images that are in jpg, bmp and gif formats and I need to enlarge them. When I do that they are all fuzzy and I have to spend a lot of time cleaning them up.

What do I need to do to scale these? Do they need to be converted to vector images?
How do I convert these images to vector images so they scale better?
Any other ideas?

While I am far less of an artist than a mechanic I would like to get better at this and the help systems for each of these products doesn't talk much about this aspect.

TIA

Yes they need to be vector images...you need Adobe illustrator or Corel draw.

Raster images can't be upscaled without quality loss; what you have been experiencing is normal. Depending on the image, converting it to vector may or may not be a simple process (more likely, not).

You need a vector based program (such as Illustrator or CorelDraw). Both programs have auto-trace features that convert the image for you. Sometimes they work well, sometimes they don't (depending on how good the source image is mostly). You might end up manually going over the images (which is more or less starting from scratch I guess), but you might not have to.
Raster images are fine for digital transfers as long as you create them in the relative size you are going to print them. For any other type of art correct printing such as screen printing or having transfers produced for you(plastisol)...you are going to need to produce camera ready artwork in a vector format. You should learn Adobe Ill. or Corel draw as most companies use these formats.
Thanks all for the replys. I am generally getting the images from customers in the file that they come with so I end up spending a lot of time either re-creating them or fixing the image once I scale it. I was looking for the 'easy button'.

Here is your easy button...I accept graphic files in these formats!!!! If your art isnt in these formats then an artwork charge will apply!!!

Yeah, I know. I am not an artist so it makes it even harder for me:eek:
youll get the hang of it after time. For the harder ones you might contract them to a freelance artist or vectorizing company.
Obviously with photographs you can't use a vector-based application. It won't do much to improve the image.

ALWAYS start with a high resolution image, and make sure you pay attention to the dots-per-inch. That should be at least 300 for printed images.

As was said before, scaling up a raster image will always cause loss of quality. You can't put information into an image that was not there in the first place. Loss of quality means not enough information.
