markh Mark Height
Specifies the watermark height. This number can either be a positive integer or a float between
When the value is a positive integer greater than
1, the value is interpreted as a pixel height. The watermark will be
markh pixels tall. The maximum value is
When the value is a float between
1.0, the value is interpreted as a ratio to the source height of the watermark. For example, when
markh is set to
1.0, the watermark will be displayed at 100% of its size. When the
markh parameter is set to
0.5, the watermark will be displayed at half of its source height.
If only one dimension watermark dimension is specified, the other dimension will be calculated according to the aspect ratio of the input image. If both
markh are omitted, then the input image’s dimensions are used.
markfit mode is set to
max, then the actual width and height may be equal to or less than the dimensions you specify.
