This is application to convert a photograph into a chalk art painting in real time.
This app changes any photograph into the chalk image which seemed to be drawn on the blackboard instantly. The three ways of color pattern , only white , three colors of blue , red , white and the natural color can be chosen . I prepared 14 original filters in total by changing the combination of extracting method of lines and density of shadow .

Because the images from device camera are directly effected , you can press the shutter button while confirming the deformed image . You can express a more delicate touch by operating three sliders prepared for each filter . With third slider you can choose one from many kinds of blackboard . The processed image can be stored in an album and reused again and again.

When you want to deform a profile photograph in an illustration style or when you want to upload a strange
photograph in Instagram or another SNS , please use it steadily.
