PosterizeImager is a tool that can create images like poster or illustration from photos with a method to decrease number of colors. Since the gradation of original image is restricted, flat coloring images like anime or comic can be got. The degradation colors also can be converted to the different color of original image using user designed color table. Since the app can draw edge lines on the boundary between same color areas, line drawing like manga can be created. For the edge lines, line width, color, or shadow can be specified, and coordinate conversion - translate, rotate, or scaling also can be applied. Moreover, copy and paste for edge lines are utilized, these can be drawn on the other images. As optional functions, pen style, edge layout like annual rings, hatching (including maze pattern) and PDF export are equipped. ※You can see many samples on Instagram with #PosterizeImager.

ReceptionRating · Positive reviews · Number of ratings

Spektrel Art holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Spektrel Art has 128 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of PosterizeImager's written reviews are positive against 88% of Spektrel Art's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency
