Can we improve screenshot DPI
Is there any way to snap a screenshot at better resolution than 96 DPI?
I pressed Win10 Windows+PrintScreen which created a screenshot PNG file. C:\Users\bram\Pictures\Screenshots\Screenshot (666).png I open it in IrfanView & select "Image Information" which tells me Number of unique colors = 74425 Current size = 1280 x 1024 Pixels (1.31 MPixels) (1.25) Current colors = 16,7 Million (24 BitsPerPixel) That doesn't tell me the DPI so I go to "Image Resize/Resample" DPI = 96 (auto calc. for cm/inches) I confirm the dots per inch with Microsoft Paint "File Properties" Resolution = 96 DPI Just curious: Is there a way to snap the screenshot at better DPI? |

(in article ): Is there any way to snap a screenshot at better resolution than 96 DPI? To what purpose? Typically DPI is used for print resolution, and with a good printer for a good quality print you would be looking for 200-360 dpi. I pressed Win10 Windows+PrintScreen which created a screenshot PNG file. C:\Users\bram\Pictures\Screenshots\Screenshot (666).png I am not a Windows, Irfan, or MS Paint user, so you are left with the experience of a Mac user from r.p.d. I open it in IrfanView & select "Image Information" which tells me Number of unique colors = 74425 Current size = 1280 x 1024 Pixels (1.31 MPixels) (1.25) Current colors = 16,7 Million (24 BitsPerPixel) That doesn't tell me the DPI so I go to "Image Resize/Resample" DPI = 96 (auto calc. for cm/inches) I confirm the dots per inch with Microsoft Paint "File Properties" Resolution = 96 DPI Just curious: Is there a way to snap the screenshot at better DPI? ....but why do you need a better resolution than you are capable of? Screenshots are typically used to the state of a process, or window at a particular time in that process. ....or if your intentions are a little more nefarious, to pilfer images. On my Mac I use SnapNDrag Pro which gives me several jpg and png quality options. For example: https://www.dropbox.com/s/elu00b4cnkiny1o/screenshot_147.jpg BTW: There is a familiar tone to your posting style. -- Regards, Savageduck |

The Wireshark program has a View : Zoom for improving the appearance of the capture. I tried some other methods and they failed to impress. Windows has a magnifier, but it doesn't change the base resolution, just doubles the pixels. Wireshark "print to PDF" sucks. Forget that. Wireshark "font size" setting, forget that. But the "View : Zoom" in Wireshark menu works OK. Then try your screenshot again. Paul |

If it's not the resolution of the screen & driver, what does determine the resolution of the Win+PrtScrn PNG screenshot then? |

| I confirm the dots per inch with Microsoft Paint "File Properties" | Resolution = 96 DPI | That means nothing. DPI only matters if you want to print. If it's 300px wide that will probably be about 3 inches onscreen (though that's not an exact 1-to-1 relationship), but it's only 1 inch on a printer that prints 300 DPI. You can switch the DPI in IrfanView, but it won't have any effect on the image. Looking at it another way: You have a picture of an apple that's 100px square at 96 DPI. You change the resolution to 300 DPI. It still shows about 1 inch onscreen and it still prints about 1/3 inch with 300 DPI printing. That's because the image is always 100 pixels square. DPI is only the calculation of how those pixels fit into a display medium. It means nothing out of context. If your screen is, say, 1600x900px then you can take a screenshot 1600x900 pixels. There are only that many pixels displaying, so there's no data to increase the resolution. If you then switch the display to be, say, 2700px wide, you'll get more pixels onscreen, but the objects will be smaller! A 32x32 icon doesn't get more pixels when you increase monitor resolution. It only has 32x32 pixels of data, no matter what you do. So you need to think of it in terms of pixels. The more pixels, the more data, the more you can enlarge. Which is why megapixels is so important with cameras. If you want to get minimal quality print of a photo you need at least 300 pixels for every inch. Thus, if you want to print a 5x7 photo at lowest usable quality, you'll need 1500 x 2100 pixels in the image, or 3+ megapixels. If you want to print it at 600 DPI you'll need an image 3000x4200px, which is over 12 megapixels. You can always enlarge the 1500x2100 image, but there's no way to get more data. The enlarging is just a mathematical formula that adds pixels while guessing at what color they should be. |

If it's not the resolution of the screen & driver, what does determine the resolution of the Win+PrtScrn PNG screenshot then? What is the source of the display image you are trying to capture? Is it a part of a web page, is it a screen capture of a document such as a PDF, WP, or spreadsheet doc? Ultimately you are limited by the native resolution of your display, the quality of the original, and the intent of the creator of the published image/document. So I will ask once again; what is your purpose for these higher resolution screenshots, why do you need the higher resolution? -- Regards, Savageduck |
