If I take screenshots under Win7 (e.g. size 600x600 pixels) and paste it into various applications they will appear with a size of ca. 15.8x15.8 cm. Because, apparently, the Windows system or the applications assume a pixel density of 96 DPI. In those applications I need an image size of 7.9x7.9 cm. So, of course, I could scale all images manually down by 50%. However, is there any possibility to directly copy the screenshot automatically in the desired size? This means, can I set somewhere that the pixel density for screenshots should be 192 DPI?
Some other suggestions (here on SuperUser and others...) Well, I can copy&paste the image to an image viewer and set (or change) the DPI to 192 and paste it to the application. However, this intermediate step and using an extra program is not very practical. Also changing the DPI value of the whole Windows system back and forth everytime is not considered as a practicable solution.
