Abstract
A user device constructs a custom color table for an imaging device and transmits the custom color table to a computing device. The computing device digitally signs the custom color table constructed at the user device. The digitally signed custom color table is deployed to the imaging device. The imaging device processes an image using the using the digitally signed custom color table.
Claims20
A non-transitory computer-readable data storage medium storing program code executable by a user device to perform processing comprising:
- constructing a custom color table for an imaging device;
- transmitting the custom color table to a computing device, the computing device digitally signing the custom color table;
- and
- deploying the digitally signed custom color table to the imaging device, the imaging device using the digitally signed custom color table when processing an image.
A method comprising:
- receiving, by a computing device from a user device, a custom color table for an imaging device constructed at the user device;
- digitally signing, by the computing device, the custom color table;
- and
- deploying the digitally signed custom color table to the imaging device, the imaging device using the digitally signed custom color table when processing an image.
An imaging device comprising:
- imaging hardware;
- a processor;
- and
- a memory storing instructions executable by the processor to:
- receive, from a removable storage device connected to the imaging device, from a user device, or from a computing device, a custom color table constructed at the user device and digitally signed by the computing device;
- and
- cause the imaging hardware to process an image using the custom color table.
