An accumulator enables feedback-based image processing for such things as the iterative painting operations or fluid dynamics simulations. It is typically used in combination with Core Image filters. The "Image" output represents the current contents of the accumulator as an image. The "Replacing Image" input allows to set the new contents of the accumulator, provided the "Replace Content" input is set to True. If the "Replacing Rectangle" inputs define a valid rectangle, only this area of the accumulat... more...

Transforms an image applying scaling, rotation and translation. more...

This patch modifies the texturing properties of an image: texture target, mipmapping levels and texturing matrix. Those texturing properties only affect the image when used as a texture by patches, while the actual contents of the image is left untouched. Note however that some patches (e.g. Billboard) may ignore those properties because of the way they use images. Also be aware that the mipmapping can only be activated if the texture target is set to 2D. more...

Reports the origin of an image in image pixels. If the image has infinite dimensions, its reported X and Y origin will be 0. more...

Crops an image to a given rectangle expressed in pixels. more...

Resizes an image to given dimensions expressed in pixels. This resizing patch should be used instead of the "Affine Transform" filter of Core Image as it is more efficient. more...

Reports the dimensions of an image in image pixels or in Quartz Composer coordinates system units. Note that the dimensions of the image expressed in units will change depending on the rendering destination's size. They are computed so that if the image were to be rendered at those dimensions, 1 pixel of the image would equal 1 pixel in the rendering destination. If the image has infinite dimensions, its reported width and height will be 0. more...

Extracts from an image the R, G, B, A values of a pixel in a given colorspace. If the source image is not in RGB, using the "Image Native" color space will be replaced by Generic RGB. more...

Calculates a 256 entries histogram for each R, G, B and A channel of a source image. The histogram values are normalized in the [0,1] range. more...
