If both the width and the height are set and one of the numbers is appended by an m, the proportions will be preserved and thus width and height are treated as maximum dimensions for the image. The image will be scaled to fit into the rectangle of the dimensions width and height.

If both the width and the height are set and at least one of the numbers is appended by a c, crop-scaling will be enabled. This means that the proportions will be preserved and the image will be scaled to fit around a rectangle with width/height dimensions. Then, a centered portion from inside of the image (size defined by width/height) will be cut out.

The c can have a percentage value (-100 ... +100) after it, which defines how much the cropping will be moved off the center to the border.

Notice that you can only use either m or c at the same time!

This crops 120x80px from the center of the scaled image:

lib.image {
    width = 120c
    height = 80c
}

This crops 100x100px; from landscape-images at the left and portrait- images centered:

lib.image {
    width = 100c-100
    height = 100c
}

This crops 100x100px; from landscape-images a bit right of the center and portrait-images a bit higher than centered:

lib.image {
    width = 100c+30
    height = 100c-25
}

GraphicsMagick/ImageMagick command-line:

fx. -rotate 90, -negate or -quality 90

Here test.jpg could have 1600 x 1200 pixels for example:

file = fileadmin/test.jpg
file.width = 240m
file.height = 240m
file.noScale = 1

This example results in an image tag like the following. Note that src="fileadmin/test.jpg" is the original file:

<img src="fileadmin/test.jpg" width="240" height="180" />

Disable cropping set by the editor in the back-end:

tt_content.image.20.1.file.crop =

Overrule/set cropping for all images:

tt_content.image.20.1.file.crop = 50,50,100,100

Use 'desktop' crop variant:

tt_content.image.20.1.file {
    crop.data = file:current:crop
    cropVariant = desktop
}

Chooses the frame in a PDF or GIF file.

"" = first frame (zero)

value should be set to the path of the file

with stdWrap you get the filename from the data-array

This returns the first image in the field "image" from the data-array:

tt_content.image.20.1.file {
    import = uploads/pics/
    import.field = image
    import.listNum = 0
}

If set, the GraphicsMagick/ImageMagick-command will use a stripProfile-command which shrinks the generated thumbnails. See the Install Tool for options and details.

If processor_stripColorProfileByDefault is set in the Install Tool, you can deactivate it by setting stripProfile=0.
