Image downsampling during processing

A system for preparing documents for printing, comprising:

• a computing device configured to:
• determine a preferred image resolution,
• receive a file comprising a first embedded image having a nominal resolution and a second embedded image,
• receive a job comprising one or more operations to be performed on the file,
• determine an effective resolution for the first embedded image,
• determine an effective resolution for the second embedded image,
• if a first object of the first embedded image is identical to a second object of the second embedded image, wherein each of the first object and the second object is a representation of the corresponding embedded image:
• determine whether the effective resolution of the first embedded image and the effective resolution of the second embedded image are within a preselected threshold,
• if the effective resolution of the second embedded image is not within the predetermined threshold of the effective resolution of the first embedded image, replace the second embedded image with the first embedded image, and
• if the effective resolution of the second embedded image is within the predetermined threshold of the effective resolution of the first embedded image, replace the second embedded image with a reference to the first embedded image, and
• downsample the first embedded image based on a scaling factor if the effective resolution for the first embedded image is greater than the preferred image resolution;
• and
• a resource configured to process a job using the downsampled first embedded image.

A method of downsampling an image, comprising:

• determining a preferred image resolution;
• receiving an electronic file comprising data representing a first embedded image having a nominal resolution and data representing a second embedded image;
• receiving a job comprising one or more operations to be performed on the electronic file;
• determining, by a computing device, an effective resolution for the first embedded image based on the nominal resolution and the one or more operations;
• determining an effective resolution for the second embedded image;
• determining whether the effective resolution for the first embedded image is greater than the preferred image resolution;
• if a first object of the first embedded image is identical to a second object of the second embedded image, wherein each of the first object and the second object is a representation of the corresponding embedded image:
• determining whether the effective resolution of the first embedded image and the effective resolution of the second embedded image are within a preselected threshold;
• downsampling the first embedded image based on a scaling factor;
• and
• processing the job, by a resource, using the downsampled first embedded image.
