Imagick::scaleImage
Scales the size of an image
Description
public bool Imagick::scaleImage(
int $columns,
int $rows,
bool $bestfit = false,
bool $legacy = false
)
Note:
The behavior of the parameter bestfit changed in Imagick 3.0.0.
Before this version given dimensions 400x400 an image of dimensions 200x150 would be
left untouched. In Imagick 3.0.0 and later the image would be scaled up to size 400x300 as
this is the "best fit" for the given dimensions. If bestfit
parameter is used both width and height must be given.
Parameters
-
columns
-
The number of columns in the scaled image.
-
rows
-
The number of rows in the scaled image.
-
bestfit
-
Whether to fit the image within the given dimensions while preserving
the aspect ratio.
-
legacy
-
Optional bool parameter.
If set to true, the calculations are done with the small rounding bug
that existed in Imagick before 3.4.0. If set to false, the calculations
should produce the same results as the ImageMagick command-line tools.
Return Values
Returns true on success.
Errors/Exceptions
Throws ImagickException on error.
