imageaffinematrixconcat()
(PHP 5 >= 5.5.0, PHP 7)
Concatenate two affine transformation matrices
说明
imageaffinematrixconcat(array $m1,array $m2): arrayReturns the concatenation of two affine transformation matrices, what is useful if multiple transformations should be applied to the same image in one go.
参数
$m1An affine transformation matrix(an array with keys0to5and float values).
$m2An affine transformation matrix(an array with keys0to5and float values).
返回值
An affine transformation matrix(an array with keys0to5and float values)或者在失败时返回FALSE
.
