Size

Resize and/or resample images. Options become available in the user-interface depending on the choices made. Check this before changing these settings: To resample or not to resample.

Size settings

Set DPI

Changes the DPI value to the specified value if checked.

Resample

Without resampling, setting the DPI value changes the physical (output) dimensions (size in mm or inches), not the number of pixels. With resampling enabled, the physical dimensions remain the same, and the number of pixels are changed accordingly. Use Resample only if the physical dimensions in the originals are known to be correct. Read more in To resample or not to resample.

If Resample is checked, following drop-down menu becomes available.

only-downsample-menu
Up- and down-sample

Always resample, whether it increases or decreases the number of pixels.

Only downsample

Resample only if it results in a decreased number of pixels

Only upsample

Resample only if it results in an increased number of pixels

Always set DPI

Change the DPI even if resampling is omitted as a result of the only-downsample or only-upsample options.

Units

Lets you choose between mm en inches as units for the size settings.

New size after resampling

Lets you choose physical dimensions. It is optional. By leaving this blank, the physical dimensions of the original image are maintained. Below is a screenshot of the associated drop-down menu:

size-options

Choose one of the options (first one is empty, physical dimensions will not be changed) and specify a value in the field next to it. See examples below:

new size

fit-in-box

Resizing is always proportional. With the “fit-in-box” example, the longest side of the image will be 512 pixels, the other side will be scaled proportionally.

fillbox

Resizing is always proportional. With the “fill box” example, if the width and height ratio of the image are not equal to the width and height ratio of the specified box, the image will be cropped. Either from top and bottom or from left and right.

Change orientation based on EXIF information

Most Operating Systems and applications display images with the correct orientation (portrait or landscape) based on the camera information that is in the EXIF metadata of images. Physical rotation of images is therefore usually unnecessary today. However, this option allows for this physical rotation, and the EXIF information is adjusted accordingly.

Maximum image/file size….

The one factor that influences the processing time of images the most is the number of pixels that the image consists of. These setting lets you define a maximum size for images in number of mega-pixels (millions of pixels). This avoids both memory problems in Claro (for extremely large images) as well as long processing times that can stagnate production.
