Detailed Description

Represents multiple methods for transforming image dimensions.

A ResizeSpec object represents some method for transforming an original set of image dimensions (A) into a new set of image dimensions (B). Supported methods include:

• METHOD EFFECT STRING REPRESENTATION(S)
• pass-through: B = A "noop", "0x0", "*0", "/0", "*1", "/1"
• fixed resize: B = newW x newH "64x48"
• uniform scale up: B = A.w*k x A.h*k "*2.5"
• uniform scale down: B = A.w/k x A.h/k "/3"
• mixed scale up: B = A.w*k1 x A.h*k2 "*3x4"
• mixed scale down: B = A.w/k1 x A.h/k2 "/1.5x2"
