Determining scaling factors for devices

A system, comprising:

• a computer processor;
• and
• logic executable by the computer processor, the logic configured to implement a method, the method including:
• determining an image as a candidate for a scaling process;
• scanning the image and identifying text in the image from the scanning;
• scaling the image to a next lower resolution, the scaling comprising reducing a set of pixel dimensions to a nearest lower rendering level;
• iteratively performing the scaling process until a threshold value of a readability metric is reached, the scaling process including:
• scanning the scaled image for scaled text;
• comparing a difference between the text and the scaled text to the difference indicative of the readability metric;
• and
• scaling the scaled image to a next lower resolution;
• and
• responsive to reaching the threshold value of the readability metric, selecting from scaled images an image having a lowest resolution resulting from the scaling process before the threshold value of the readability metric was reached;
• wherein the readability metric is calculated as a function of a Levenshtein Distance between the text and the scaled text, and a length of the original text.
