On browsers that don't support srcset, the browser simply uses the default image file specified by the src attribute. This is why it is important to always include a 1x image that can be displayed on any device, regardless of capabilities. When srcset is supported, the comma-separated list of image/conditions is parsed prior to making any requests, and only the most appropriate image is downloaded and displayed.While the conditions can include everything from pixel density to width and height, only pixel density is well-supported today. To balance current behavior with future features, stick with simply providing the 2x image in the attribute.Art direction in responsive images with picture #To change images based on device characteristics, also known as art direction, use the picture element. The picture element defines a declarative solution for providing multiple versions of an image based on different characteristics, like device size, device resolution, orientation, and more.The picture element is beginning to land in browsers. Although it's not available in every browser yet, we recommend its use because of the strong backward compatibility and potential use of the Picturefill polyfill. See the site for further details. Use the picture element when an image source exists in multiple densities, or when a responsive design dictates a somewhat different image on some types of screens. Similar to the video element, multiple source elements can be included, making it possible to specify different image files depending on media queries or image format.

For extreme size changes, we may want to change the layout altogether, either through a separate style sheet or, more efficiently, through a CSS media query. This does not have to be troublesome; most of the styles can remain the same, while specific style sheets can inherit these styles and move elements around with floats, widths, heights and so on.

So with the help of these values, we can scale the SVG vector and change the direction of it (i.e make it to left, right, top or bottom) based on the value defined in the width and height property in the SVG element.

Here, the square box shows the border for the SVG and with viewBox attribute we can set the scale and pan for the vector. The output for both of the above SVG elements are same. We set the width and height for SVG and viewBox equal (i.e 200) so we are getting both the circles of the same size.

Values of width and height: With the width and height values you can change the size of the SVG vector. So, if we want to change the size and make it larger, then set the value for width and height, in viewBox, smaller then the width and height properties of the SVG element.

These few lines of Python code resize an image (fullsized_image.jpg) using Pillow to a width of 300 pixels, which is set in the variable basewidth and a height proportional to the new width. The proportional height is calculated by determining what percentage 300 pixels is of the original width (img.size[0]) and then multiplying the original height (img.size[1]) by that percentage. The resulting height value is saved in the variable hsize.

Many Arduino projects use monochrome display, one of the reason is the limited resources of a MCU. 320 pixels width, 240 pixels height and 8 bits color for each RGB color channel means 230 KB for each full screen picture. But normal Arduino (ATmega328) only have 32 KB flash and it is time consuming (over a second) to read data from SD card and draw it to the color display. 041b061a72
