Plot Image Resolution For Free

Setting the Default DPI DPI stands for dots per inch. It's a measure of the resolution of your plots. The higher the DPI, the more detail your plot will have. The default DPI in matplotlib is 100, but you can change this using the rcParams attribute, just like we did with the figure size.

When creating plots using Matplotlib, you get a default figure size of 6.4 for the width and 4.8 for the height (in inches). In this article, you'll learn how to change the plot size using the following: The figsize() attribute. The set_figwidth() method.

Higher resolution photos are clearer and contain more detail. Digital image resolution is expressed as pixels (or dots) across by pixels down, such as 640 x 480, meaning 640 pixels across by 480 pixels down. The best printable resolution is 300 dots per inch. Extremely low resolution will look "blocky" or pixelated.

In many cases, the best resolution for printing is 300 PPI. At 300 pixels per inch (which roughly translates to 300 DPI, or dots per inch, on a printing press), an image will appear sharp and crisp. These are considered to be high resolution, or high-res, images.

To change the image's resolution in matplotlib, we have to change the value of the key 'savefig. dpi' in the matplotlibrc file. The above syntax will change the dpi of the image to 300.

Generally, 300 DPI is great for small prints, while 600 DPI is amazing for large prints. If you're scanning documents or photos to be used on the web or in emails, 300 dpi is more than enough. If you want to print large photos or blow them up to poster size, 600 dpi will give you better results.

However, now that most computer screens are HD, best practice is to aim for a higher resolution than 720 for web use and streaming. Often referred to as ?full HD,? 1080 (1920 x 1080 pixels) has become the industry standard for a crisp HD digital video that doesn't break your storage space.
