It works by loading an image using the PHP GD2 library function ImageCreateFromJpeg() and then figures out the height and width of it. Good results, you need to use a rather small font.Use the following snippet to convert any jpeg image into the equivalent image in ASCII format. This nice photo of Gumbrecht was converted using a noise of 0.25.Ĭonverting photos is even harder than just simple gradients as above. $ java -jar jitac-0.2.0.jar -w 70 -f fixed05x07 -n 0.25 -o gumbrecht.asc gumbrecht.jpg It's quality is even better than the image converted with all input colorĬhannels due to the fact that a blue channel mask improves red and greenĬolors in the result if no output color channel mask is used. The image at the right most has been converted using a blue input color The images to the right show how color mask filtering improves the output Jitac has three color flags: red=1, green=2Īnd blue=4. By using color masks you are able to filter colorsĪt the input and at the output. The possibilities of HTML files allow the usage of colors and some color escaping > and < and byĪdding a simple header and footer to the output. Since version 0.2 Jitac is able to convert images into HTML pagesīy adjusting the characters, e.g. $ java -jar jitac-0.2.0.jar -c 6 -C -o izab.html izab.jpg HTML conversion with color, only blue and green channel $ java -jar jitac-0.2.0.jar -C -o izab.html izab.jpg $ java -jar jitac-0.2.0.jar -H -o izab.html izab.jpg The first image shows the source, the second a conversion with no noise,Īnd the third a conversion with noise 0.37 (37% noise in characters). Trick, that is used in most neural network algorithms. In order to avoid this behaviour, Jitac uses a The character with the smallest distance is chosen asĭue to the fact that characters are black and white images, gradients areīadly converted because the white space character often has the smallestĭistance to the blocks. This is done by interpreting the block and allĬharacters as vectors and computing the Euclidean distance between the blockĪnd all characters. In normal mode Jitac finds the character that best matches a givenīlock of the image. Working with photos or images that have fine granulated gradients is moreĭifficult. $ java -jar jitac-0.2.0.jar -n 0.37 -o gradients.asc gradients.gif $ java -jar jitac-0.2.0.jar -o gradients.asc gradients.gif The image was converted using Jitac 'out-of-the-box', no special options Result is quite good, even if displayed with a medium sized font. The characters can follow the fine contours and the Those images are idealįor ASCII conversion.

Yes, you guessed right, this is a cute console application that converts high-quality images into oldschool ASCII art. Jitac is an image to ASCII converter written in Java.
