Some time ago I presented a formula to plug into Equations to warp text along a wavy baseline. I promised to create a macro to perform this, but never got round to it. Well here is that macro and a library containing it. Wavy Text.afmacro Wavy Text.afmacros The transformation is just a sine/cosine curve: y=y-(h*a/3)*(b*sin(360*x/w/c)+(1-b)*cos(360*x/w/c)) The a parameter determines the amplitude. The default is a=0.5, which creates a wave that reaches about half way to the top and bottom of the layer. The b parameter shifts the position of te wave along the horizontal axis. The c parameter affects the wavelength. Reducing c gives more waves along the x-axis. If you start with a text layer such as: and apply the macro with the default parameters, you get: The macro is designed to operate on a text object on a background. It needs the background to give it room. It begins by rasterizing the text to a pixel layer. It uses the height and width of the background layer to determine the amplitude and wavelength, not the height and width of the text itself. To use this, I would suggest creating a new document of a size to hold the text, then warp it, then place or copy it into the target document with an appropriate blending mode. John
Hello, Just got Affinity Photo for iPad. Great app, thank you very much. I was wondering if there was any plans to create a Wave distortion filter, like Adobe Photoshop has. You can see an example of the Photoshop Wave filter in action right here: https://youtu.be/1CcdLwCRuQ0 You can create really cool glitch effects with this Photoshop filter. As a creator of glitch art I would love to see this added to Affinity Photo. I also think it would bring a lot of new users to Affinity Photo. Thank you.
