I want to put a (non-image) portion of my website on a t-shirt, and to do so I need a high-resolution image of the relevant part. My thought is to tell some utility "take a screenshot of this webpage at such and such resolution" and then cut out the part that I want.

Is this the right approach? Does anyone know of such a utility?

If using Vista, you could use the Snippet utility. –  James Atkinson Aug 27 '09 at 17:35

If you're using Windows Vista or 7, just go to "Start" - "All Programs" - "Accessories" and utilize the Snipping Tool to make a screenshot on your browser. And if you're Windows 8 user, you may right-click on the Start screen, hit the option of "All Apps" and then navigate to this tool inside the "Windows Accessories".

However, the Snipping Tool cannot capture scrolling webpage and does not allow you to add text to the image. Thus, sometimes I prefer to use a third-party free app called webpage screenshot capture, for it lets you snapshot the whole webpage by entering a URL. Also, it provides more editing options. Hope it helps.

Paparazzi (for Mac) works really well for capturing webpages. Export as pdf, tiff, png, or jpg files.

We had a Norwegian student that only wanted to print some of a very long webpage (http://www.wilsonminer.com/posts/2006/may/10/are-you-generic/ this was the actual page). PrintWhatYouLike.com helped very much, is free and is very easy to use.

PrintWhatYouLike.com

It's a free website that lets you format any web page for printing.

You start by entering the URL of the page you want to print. The PrintWhatYouLike online editor lets you remove, resize, and rearrange the page elements quickly so you can print only what you want.

It works pretty well for me, I tested it in IE8, Firefox 3.5 and Chrome

Just use it to print to a PDF file and it's perfect!

If you zoom in and then use Abduction or CaptureIt!, it should work, they both auto-scroll. I do like the print to PDF idea though, assuming all you backgrounds are preserved.

Abduction doesn't work - it doesn't respect your zoom, and captures the page at original size. Don't know about CaptureIt!, I can't find it. –  SamStephens Feb 1 '12 at 22:19

You could print the page to a PDF document. This way, the text is rendered using vectors and will hold up much better in high resolution print.

Most print is done in 300dpi. Text will go as high as 1200 or even 2400dpi sometimes. Your screen on the other hand is typically 72 - 96dpi. So, if your page is text-heavy, it'll end up looking a lot sharper and crisper printed compared to its on-screen version.

More information about DPI here: http://www.nikon-euro.com/nikoneuro_en/hit/general/en/HIT_gen_en_17.htm

The nice thing is the PDF is probably going to also be inherently usable by your shirt printer. –  John Rudy Aug 27 '09 at 19:05

This doesn't exactly work if there is a print stylesheet that changes the formatting of the page. –  Andrew Jul 28 '11 at 14:53

You don't need external programs.

Magnify the webpage by zooming in (big enough till you want it), then make firefox into full screen mode. Press Print Screen button to take a screenshot, open mspaint and paste the screenshot in.

Probably the screenshot you like is not big enough, if so, you can zoom in even more, take more screenshots and meld multiple screenshots together to form a big one.

You will just be limited by the actual resolution of the thing being zoomed in on. At some point it will start looking grainy. –  dagorym Aug 27 '09 at 18:25

@dagorym, since he specifies it's a non-image portion, everything should maintain hi-res while scaling. And in Chrome it scales linearly, looks good. –  hyperslug Aug 27 '09 at 18:28

Also, be sure to set your display resolution to the highest setting prior to taking the screenshot. [Right click the desktop select properties (2k/XP) or Personalize (Vista/7).] –  Duey Aug 27 '09 at 18:28

@hyperslug: Don't you love WebKit? Apple wrote the rendering engine for Chrome. I don't like Apple, but I love their work on WebKit. –  John Gietzen Aug 27 '09 at 18:42

Screengrab! It can copy/save the page/frame/visible portion/selection/window of Firefox.

Screengrab is End Of Life unfortunately - the author can't keep up with the pace of Firefox change. –  SamStephens Feb 1 '12 at 22:20

You can only take a screen shot at screen resolution. Every operating system you might be using has screens-shot functionality built-in.

PRINT-SCREEN on Windows (then paste into MSPaint or whatever) or Command Shift 3 or F3 or something on Mac, and it poops the image onto your desktop.

Don't forget you can use ALT+Print-Screen in windows to capture just the window in question. This helps if you're on multi-monitor setups and don't want to have to worry about cropping the images from the second monitor. –  Dillie-O Aug 27 '09 at 18:11

I love MWSnap. It will keep the current screen resolution and allows you to select the sections you want, or crop later.

AFAIK, you cannot take a screenshot outside the resolution you are already using. For a website, increasing the resolution should not have any effect.

(And it is free) http://www.mirekw.com/winfreeware/mwsnap.html

EDIT: If you designed it in photoshop and have not rasteurized the image yet, you can increase the resolution there, but not from the browser.

I like MWSnap too. The only "complaint" I have about this is that there are no newer versions coming out. –  Isxek Aug 27 '09 at 18:20
    
I agree... the fact that it only works on the primary monitor for multiple monitor set ups drives me insane some days. –  RiddlerDev Sep 1 '09 at 22:25
