Image shape 1 1 1 2 2:1 aspect ratio 1:1 aspect ratio aspect ratio – width:height 4 3 9 16 6 4 common aspect ratios 6:4 16:9 4:3

resize, same aspect ratio resize, different aspect ratio images are made of dots called “pixels”

200 x 200 = 40,000 pixels 100 x 100 = 10,000 pixels 50 x 50 2,500 pixels Number of pixels 200 x 200 = 40,000 pixels 100 x 100 = 10,000 pixels 50 x 50 2,500 pixels Resolution The images are all the same size, but the high resolution image on the left has the most pixels. Coffee cup pixels

Flat versus photographic images Logos in addition to other images with a limited color palette Photographic images with continuous tone variation Common Internet image file types .gif: Graphic Interchange Format, used as long as logos, cartoons in addition to other flat art with up to 256 different colors .png: Portable Network Graphics, gif replacement (more colors), but cannot do animation .bmp: Microsoft Bitmap, an uncompressed as long as mat used as long as photographic images .jpeg (or .jpg): Joint Photographers Expert Group, a compressible as long as mat used as long as photographic images Compression – making the file smaller, but reducing image quality. More on this later. Which to use .png (use .gif if animation or compatibility is an issue) .jpg (use .bmp if file size is not an issue)

A few questions We covered five characteristics of an image – without looking back, do you recall them More important – do you know what each means Two images have the same aspect ratio, but they are different sizes. How can that be If you try to take a picture immediately after taking another, there is a slight delay. Why If you are looking through some pictures you just took, why is there a slight delay as it advances from one to another (Hint – go back to our presentation on the components of a computer system).

200 x 200 = 40,000 pixels 100 x 100 = 10,000 pixels 50 x 50 2,500 pixels Which of these images has the largest pixels The resolution of an image is determined by the number of pixels it contains in addition to -. An image is 800 pixels wide in addition to 200 pixels high. What is its aspect ratio An image is 640 pixels wide in addition to 480 pixels high. What is its aspect ratio An image is 800 pixels wide in addition to 400 pixels high, in addition to I resize it to 100 pixels high, while maintaining the aspect ratio. What is the new width

If an image has a 1:1 aspect ratio, in addition to it is 10 inches wide, how tall is it If an image has a 2:1 aspect ratio, in addition to it is 10 inches wide, how tall is it If an image has a 4:3 aspect ratio, in addition to it is 10 inches wide, how tall is it If an image has a 16:9 aspect ratio, in addition to it is 10 inches wide, how tall is it Image characteristics Skills: none IT concepts: image characteristics: size, shape (aspect ratio), number of pixels, resolution in addition to file type, pixel This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 3.0 License.
