--- Comment #18 from Konstantin <[email protected]> --- Created attachment 195112 --> https://bugs.kde.org/attachment.cgi?id=195112&action=edit Scr I've been thinking about your words for a long time and I think it's possible to make an algorithm that doesn't blur screenshots. And it's really 100%. If I take a screenshot of the entire screen, then I'm fine, but if I take a screenshot of the highlighted area, then it's just terrible. The screenshot shows part of the screen if I take a screenshot of the entire screen, and below is a screenshot of the same area separately. You can make sure that when you take a screenshot of the Spectacle area, you take a screenshot of the entire screen and cut out the selected area. Then everything will be fine. The main thing is that it does not lose quality during this cutting operation. Yes, I have a 4K monitor with a scale of 125%, but if you can take a screenshot of the entire screen without distortion, then you can take a screenshot of a part of it without distortion. I don't think this is a question of whether the 100% screenshot looks blurry when viewed on my 4K@125% display. The important comparison is between two screenshots produced on the same display: a crop taken from a native-resolution Full Screen screenshot; a Rectangular Region screenshot of exactly the same area. If the Full Screen capture contains the area at its native physical pixel resolution, then cropping that image does not require any scaling and cannot reduce image quality. For example, if an area occupies 1250×600 physical pixels on my 4K@125% screen, I would expect both the crop from Full Screen and the Rectangular Region capture to be 1250×600 pixels. If Rectangular Region instead produces 1000×480, that means it is being captured/exported in logical coordinates (physical / 1.25) and then has to be upscaled when displayed. So I think the useful test here is not comparing how icons look on different 100%-scaled monitors, but comparing the pixel dimensions of the same region in a Full Screen capture and in a Rectangular Region capture. In fact, cropping the native Full Screen screenshot would be a perfectly lossless solution: the pixels can simply be copied without resampling. -- You are receiving this mail because: You are watching all bug changes.
