For example, if the resolution is 300 dpi, but you want to increase the image size by 200%, change the resolution setting to 600 dpi. If you want to increase the image size by 400%, change the resolution setting to 1200 dpi.
Some people may be satisfied with 100 dpi (about NEWSPAPER photoquality) 8x10 = 100x8 x 100x10 = 800x1000 = .8 meg/pixels. MOST people would be "satisfied" with 200 dpi 8x10 = 200x8 x 200x10 = 1600x2000 = 3.2 meg/pixels. The "ultimate" desirable (excellent photo) = 300 dpi 8x10 = 300x8 x 300x10 = 2400x3000 = 7.2 meg/pixels. Peter_pd
Convert pixels/inch [PPI] to dots/inch [DPI]: 1 PPI = 1 DPI; 1 DPI = 1 PPI. 1 PPI = 1 DPI: 5 PPI = 5 DPI: 10 PPI = 10 DPI: 25 PPI = 25 DPI: 50 PPI = 50 DPI: Dot/inchAcercamiento de la imagen impresa a 1200 DPI. Como pueden ver en las imágenes, entre 300 y 600 DPI hay una diferencia notoria, pero entre 600 y 1200DPI las imágenes son casi idénticas. Tenemos que considerar además que estamos haciendo un «acercamiento» a las imágenes, o sea algo así como verlas muy, muy de cerca.
300 DPI is a minimum image size for printing, but the more the better. If this parameter is less, the visual will be of very low quality, pixelated and blurred. So, if you are choosing between 300 DPI and 600 DPI, the latter is always a better option. Clideo's 300 DPI converter is online and free. It allows you to choose the needed DPI among
The 300 dpi images print well and reasonably quickly on existing laser printers, many of which are not capable of 400 or 600 dpi printing. The grayscale images that were heavily compressed with the JPEG algorithm were not favored because of the challenge at print time and the visibility of JPEG image artifacts.
\$\begingroup\$ REF: No and no. In your second reference, it clearly shows on the webpage 3 identical kitty photos. The PPI info embedded on a jpg file is just a SMALL recommendation to the user's printer, that can be overrun, overwrite, forgotten into oblivion if the user turn on the fit to page checkbox for example.
Dots per inches (dpi) determines how many pixels the figure comprises. The default dpi in matplotlib is 100. A figure of figsize= (w,h) will have. px, py = w*dpi, h*dpi # pixels # e.g. # 6.4 inches * 100 dpi = 640 pixels. So in order to obtain a figure with a pixel size of e.g. (1200,600) you may chose several combinations of figure size and
