Transformation You can set the overall size of a layer with the scale slider. The aspect ratio allows for unproportional scaling: width and height are scaled differently. You can rotate and flip a layer, and you can distort it horizontally or vertically with the shear sliders. To mirror an image (for instance to make a reflection,) rotate it 180 degrees and flip it. You may also want to decrease its opacity and adjust its aspect ratio to give the illusion of perspective. |
Opacity The opacity slider controls the 'see through' or coverage of the layer. This can also be termed transparency or, to be technical, the alpha channel. It's a value associated with each RGB pixel that specifies how much that pixel should cover what's underneath it. This makes masking, blending and 'holes' in images possible. |
Color A click on a color patch in the layer controls or a palette icon in the layer list brings up the OS X color picker. Colors can be represented in many different ways - rather than using RGB, iFuntastic uses the HSV representation for colors:
Colorize lets you change the color of the whole image with the hue slider. |
Masking The masking functions let you use an image as a mask. Using an image as a mask determines the 'see through' of the layers underneath. The Mask converts the image into a mask; it works best with grayscale images. Black areas will become transparent, white areas will cut out lower layers and gray will become an in-between value. Invert inverts this behavior. Hard forces the grayscale values to make up their mind: black or white. Pick some of the provided images in the 'OverlaysAndMasks' folder on disk to experiment with this functionality. Screen lets you choose a color in an image which will become transparent. Option-click on the image in the edit area to choose the color from the image, or click on the color patch control to set it with the color picker. Use this function to cut out images that have a uniformly colored background. (The weatherman on your TV usually stands in front of a blue or green screen - software then replaces that color with a weathermap.) |
