High Resolution Screen Capture

You sure? The printscreen key should capture exactly the pixels on your monitor(s) to the clipboard. It will look like crap if you print a 100 DPI screen to a 600 DPI printer, or if it gets scaled on the same monitor to other than an integral multiple of 100% (in Photoshop, use "actual pixels"). On my CAD machine it produces an image 5120 x

1600 pixels, which is just adequate for a 7" x 5" at 300DPI (17" x 5", actually).

I tried printing to PDF at 600dpi... looks crappy unless you zoom in.

Didn't think to use Photoshop. "N" has that, I'll try it. ...Jim Thompson

Screen capture with Print Screen and alt-print screen are at screen resolution, not sure why you don't see the same results.

I've had the same issues when trying to get screen shots for documentation. Found it best to either maximize a window or do an ALT PrtScreen to get just the current window. Best to maximize the window so you get the best resolution.

There are a few programs for screen capture that come up when searching for "screen capture" windows

I've always used Paint Shop Pro 4.12. It can capture the full screen, a window, an area, and a couple of other modes, and it's pixel for pixel.

Good Luck! Rich

Yea, then why use MS.

If print screen has got you down, try MWSnap. Been using it for a year or so and it works well.

I use SnagIt. Got it free at some trade show I attended. It's very capable. It can even capture web pages that scroll off the screen.

Jim Thompson:

It has to, since the "standard" monitor resolution is 75 DPI.

If you have a monitor 15" wide with a resolution of 1280 pixel, your screen resolution is 85,33 pixel per inch.

You can use software tricks to reduce the "pixelation" of the image by smoothing the border between one pixel and the next, but the resolution will remain the same.

Or you can print it 1:1, but the dimension of the printout will be about

1/10 of the screen.

Nice. But I can't understand Jim's concern. I do CRTL-PrintScreen a lot and always get full-res rendering. On IrfanView it might look fuzzy but once stored or copied into Word or wherever it looks just fine. Or in last-century terms WYSIWYG.

Jim, this is another thread where you post must have gotten whacked somewhere, at least it didn't show up on news.individual.de. Did you make the Germans mad with something? Or didn't pay a ticket there? :-)

He must have. I rarely see his original articles. Sometimes his posts screw up threading, too.

I ctrl-V'd into PaintShopPro, then printed to PDF. Wonder if you can ctrl-V straight into Adobe?

You have a lousy news feed. I've never gotten a ticket in Germany. HOW would one do that? On the autobahn there's no limit. Maybe in a little 'burg, but that's usually too hilly to risk blind high speed. ...Jim Thompson

Hmm, you know what would be really cool? A "screen shot" which actually records GDI objects. I suppose it would have to be driver level though. It would allow at least some objects to be captured with unlimited resolution (i.e., TrueType / ClearType characters), or to change the "Theme" of the capture.

In principle, this would also allow unlimited resolution of other objects as well (buttons, etc.), though I suppose most are described by bitmaps anyway.

PrntScrn in Windows is a 100% every pixel capture. Just open paint and hit Ctrl-V. It even captures BOTH screens perfectly and they are not even the same res

You can get the Window handles. As I understand all controls are actually windows, at least for custom controls. So that?s a start. Now actually getting the control objects is another matter. But the controls can be listed, eg Excel VBA project, So there probably is a way to do it. Why would you want this anyway?

Try ParaBen Sceen Capture..

As others have alluded, screen capture simply captures the pixels on your screen exactly as they are so the problem isn't with screen capture, per se, it's what's done with it later.

The confusion comes from 'DPI'. DPI has meaning to printers, as that's how they print, but none to the display screen. By that I mean a 1280x1024 screen is 1280x1024 whether on a 15" screen, 20" screen, or projected to wall size and, clearly, those are different 'DPI' for the same pixels.

However, screen capture, for obscure historical reasons, sticks 72DPI in as a default 'to have something' but it has no 'real' meaning since, assuming you did a full screen capture, it's simply 1280x1024 pixels.

But when you stick the capture into a program that knows it's going to print on paper all of a sudden that default 72dpi takes on a real meaning. It thinks you've got a 17.778" x 14.222" picture at 72DPI. (Note that this makes absolutely no difference to displaying it on the screen as it's still the same pixels. It's going to *paper* that's the problem)

The simple answer is to change the DPI. In Photoshop, when you select 'new file', to then paste the capture into, change the DPI setting in that dialogue box from the default 72 to whatever you would like, such as 300DPI, which will magically change the 'size' to 4.267" x 3.413". Or 600 DPI for half that size (2.133" x 1.707"). Then, when you put it into PDF (or another 'print' program) it will think the picture is that size with that resolution.

If it's already 'saved' somewhere with 72DPI (or something else you would like to change) you can alter it in Photoshop with "image size." Just turn off the "resample image" check box and it'll do the magic size change when you alter the DPI. (If you leave resample on it thinks you want the size to remain the same so it interpolates pixels to 'increase' the DPI to the new value. You don't want that as you'll still have the 18" picture, with a 'faked' increase of resolution that has no 'real' increase to go with it, and the print program will still need to 'scale down to fit'. It also makes a HUGE file with the increased size of no value.)

(If you don't have Photoshop then Gimp will probably do it but I don't have that on this machine to check the menu options. I'm sure there are others as well.)

Note, if you're going to be resizing (after the DPI change) for print it's better to turn off clear type, and any other 'display enhancements', as that tends to 'fuzzy up' text, to make it more pleasing to the eye, but that 'fuzz' doesn't generally scale as well as crisp text. It depends on how much resizing you're doing (magazines often erase the text and re paste it with an editor, e.g. photoshop).

Another note, changing 'DPI' in Windows display properties has no effect on the screen capture DPI since the screen is still simply

1280x1024. That 'display DPI' is a 'logical' (as in the computing term) fabrication to set character size, not 'resolution', which is why it seems to be backwards. I.E. if it were really 'DPI' then 120 would be smaller type than the default 96 but it works the other way as it's more akin to 'pixels per thing to display' than 'per inch'. I.E., use 120 pixels instead of 96 when constructing the 'thing' and, since 'DPI' is 'fixed' by the pixel resolution on your size screen, that makes the 'displayed thing' bigger as it takes more pixels to make it. Screen capture, however, will still be 1280x1024 at a dummy default 72DPI.
