Enumerations

enum class Enum : uint8_t

Name	Value	Comments
kIdentity	0	Image pixels are passed through without any change.
kReflectX	1	Image pixels are reflected across a line meeting the image's center, parallel to the X axis. This enum member's numeric value has a single bit set to 1. Any transformation whose value has this bit set involves an X reflection. This transformation is also called an "X flip". Example: \|a b c d\| \|i j k l\| \|e f g h\| -> \|e f g h\| \|i j k l\| \|a b c d\|
kReflectY	2	Image pixels are reflected across a line meeting the image's center, parallel to the Y axis. This enum member's numeric value has a single bit set to 1. Any transformation whose value has this bit set involves an Y reflection. This transformation is also called an "Y flip". Example: \|a b c d\| \|d c b a\| \|e f g h\| -> \|h g f e\| \|i j k l\| \|l k j i\|
kRotateCcw180	3	Image pixels are rotated around the image's center counter-clockwise by 180 degrees. This is equivalent to applying the `REFLECT_X` and `REFLECT_Y` transforms. `REFLECT_X` and `REFLECT_Y` are commutative, so their ordering doesn't matter. Example: \|a b c d\| \|l k j i\| \|e f g h\| -> \|h g f e\| \|i j k l\| \|d c b a\|
kRotateCcw90	4	Image pixels are rotated around the image's center counter-clockwise by 90 degrees. The image produced by this transformation has different dimensions from the input image. This enum member's numeric value has a single bit set to 1. Any transformation whose value has this bit set involves a 90-degree counter-clockwise rotation. Example: \|a b c d\| \|d h l\| \|e f g h\| -> \|c g k\| \|i j k l\| \|b f j\| \|a e i\|
kRotateCcw90ReflectX	5	Image pixels are transformed using `ROTATE_CCW_90`, followed by `REFLECT_X`. The image produced by this transformation has different dimensions from the input image. Example: \|a b c d\| \|a e i\| \|e f g h\| -> \|b f k\| \|i j k l\| \|c g k\| \|d h l\|
kRotateCcw90ReflectY	6	Image pixels are transformed using `ROTATE_CCW_90`, followed by `REFLECT_Y`. The image produced by this transformation has different dimensions from the input image. Example: \|a b c d\| \|l h d\| \|e f g h\| -> \|k g c\| \|i j k l\| \|j f b\| \|i e a\|
kRotateCcw270	7	Image pixels are rotated around the image's center counter-clockwise by 270 degrees. The image produced by this transformation has different dimensions from the input image. This is equivalent to applying the `ROTATE_CCW_90` transform, followed by `REFLECT_X` and `REFLECT_Y`. `REFLECT_X` and `REFLECT_Y` are commutative, so their ordering doesn't matter. Example: \|a b c d\| \|i e a\| \|e f g h\| -> \|j f b\| \|i j k l\| \|k g c\| \|l h d\|
