Image Geometry Correction (often referred to as Image Warping) is the process of digitally manipulating image data such that the image’s projection precisely matches a specific projection surface or shape. [1] Image geometry correction compensates for the distortion created by off-axis projector or screen placement or non-flat screen surface ...
Image warping example. Image warping is the process of digitally manipulating an image such that any shapes portrayed in the image have been significantly distorted. Warping may be used for correcting image distortion as well as for creative purposes (e.g., morphing [1]). The same techniques are equally applicable to video.
Texture mapping [1] [2] [3] is a term used in computer graphics to describe how 2D images are projected onto 3D models. The most common variant is the UV unwrap , which can be described as an inverse paper cutout, where the surfaces of a 3D model is cut apart so that it can be unfolded into a 2D coordinate space (UV Space).
In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...

The interpolated surface (meaning the kernel shape, not the image) is smoother than corresponding surfaces obtained by bilinear interpolation or nearest-neighbor interpolation. Bicubic interpolation can be accomplished using either Lagrange polynomials, cubic splines, or cubic convolution algorithm.
SAI displays white and transparency in the same way, which may cause significant display differences when exporting to another program, such as Adobe Photoshop. There is also no printing functionality, but documents can be exported in a range of popular formats, such as .PSD or .BMP files, in addition to the native .SAI format.
Creator was set up to be a modular system, tailored to the specific needs of each "shop" or user. The base for version 7.0 was the "CT-Brix" software library (colour selection, basic compositing, selection, transformation, shapes, basic colour correction, densitometer, layers etc.), also featured in other Barco Graphics CT (continuous tone) products, e.g. ColorTone.
