Convert Images to ASCII Pictures
Convert any image to ASCII picture by representing each pixels grayscale value as an ASCII character. The higher the grayscale value resp. the lighter the pixel the more space the corresponding ASCII character fills on the screen therefore reassembling the image well on dark console backgrounds with light font colors. On light console backgrounds with dark font colors use the
-Invert switch to adjust. Before being processed the image will be resized in memory to make the resulting ASCII picture fit the console's width later on. To fit the console's height instead use the
-FitConsoleHeight switch. Otherwise, if you don't want the resulting ASCII picture's dimensions determined by the script automatically at all you can specify a custom width and height using the
-Height parameters. This can be useful when exporting ASCII pictures of custom sizes into textfiles, e.g (Note:
i2a is an alias for
gci .\bobby-fischer.jpg | i2a -Width 160 -Height 80 -Resolution Mid -Invert > .\bobby-fischer.txt
-Height must be specified manually when running the Cmdlet from PowerShell hosts not reporting its console dimensions like PowerShell ISE.
Furthermore, the Cmdlet supports three different resolutions regarding the resulting ASCII picture. These are
High and can be specified by the
-Resolution parameter. On higher resolutions the resulting ASCII picture will be made up with more ASCII characters yielding a more fine-grained picture. Depending on the image a higher resolution sometimes may tend to look better especially when using smaller font sizes or bigger dimensions.
