I was wondering if someone might know the cause behind my fuzzy screengrabs. They're nothing more than printscreens saved as JPEG files.

Any help is greatly appreciated.

Looks like you need to turn up the quality of the JPEG. JPEG is a 'lossy' format that 'throws' data away when you turn down the quality (or increase compression).

Try png instead. For wireframe and node-tree screengrabs, it's pretty much unbeatable. :)

High compression value?

Yep looks like good old JPG compression. If you want a cool printscreen utility check out Gadwin Printscreen. It's free and does all sorts of cool things.

tHANX for the feedback everyone. The thing is, I wasn't having this kind of problem, until the last 3 or 4 times I grabbed a screen to share info here. I must of accidentally changed a setting somewhere. I'll look into your suggestions and get back to you.

I thought that maybe I just needed stronger glasses. :lol:

Do you only notice the degration in quality when you open up your saved file? If I print screen into Paint Brush or PhotoShop, no compression has happened until I save it. If it looks fuzzy before saving, then that would be strange.

Actually looks like a low resolutiion video image [640x480]. but yeah, if you save a file to .jpg format at say low quality you will soften the image. kinda how years ago all digital cams and video cams had soft look due to limited resolution.

Nope, it only gets fuzzy after I export it out of the illustration program I'm using.

I think you might have just hit the nail on the head. Do you have any suggestion on what settings would be appropriate to get rid of the fuzzies?

JPEg Setting 6~8 or 'High' will usually do the trick.

Perhaps use another 'illustrator program'... which one are you using?

CorelDRAW

I try to set the compression/quality levels to keep the file size below 1 meg. If the file size goes above 1 meg, I have trouble uploading it to the forum.

Medi8or is right, for screen shots where a lot of screen is the same colour, PNG would be better. JPEGs are better for photographs, or images with LOTS of changing detail.

Let's see how this looks. This is a screengrab saved as a PNG file.

160 x 120

Here's Take 2.

1024 x 767

This is just an even aspect ratio of the one-to-one size.

Ohhhh, much-o better-o! :thumbsup:

Don't you think?

I'll have to remember PNG when I'm saving Screengrabs.

The projected file size was over 40 meg, but the end file size was just under 90 k. Go figure.

tHANX everyone, for all your help!:) :) :)

Or try GIF, it only has 256 colors, but hey, you can actually count the amount of colors used in LW on both hands.
