Abstract
In some examples, dithering based color conversion may include ascertaining an input color value. Based on conversion of the input color value to an output color space representation, a set of nodes that are to be analyzed to control operation of a printer may be determined. Based on a position of the input color value from each node of the set of nodes, a corresponding probability associated with each node of the set of nodes may be determined. Further, the operation of the printer may be controlled based on the determined probability associated with each node of the set of nodes.
Claims15
An apparatus comprising:
- a processor;
- and
- a non-transitory computer readable medium storing machine readable instructions that when executed by the processor cause the processor to:
- ascertain an input color value;
- determine, based on conversion of the input color value to an output color space representation, a set of nodes that are to be analyzed to control operation of a printer;
- determine, based on a position of the input color value from each node of the set of nodes, a corresponding probability associated with each node of the set of nodes;
- and
- control, based on the determined probability associated with each node of the set of nodes, the operation of the printer.
A computer implemented method comprising:
- ascertaining an input color value;
- converting the input color value to an output color space representation based on analysis of a multi-dimensional lookup table;
- determining, based on the converting of the input color value to the output color space representation, a set of nodes from the multi-dimensional lookup table that are to be analyzed to control operation of a printhead;
- determining, based on a position of the input color value from each node of the set of nodes, a corresponding probability associated with each node of the set of nodes;
- and
- controlling, based on the determined probability associated with each node of the set of nodes, the operation of the printhead.
A non-transitory computer readable medium having stored thereon machine readable instructions, the machine readable instructions, when executed, cause a processor to:
- determine, based on conversion of an input color value to an output color space representation, a set of nodes that are to be analyzed to control an operation of a thermal printhead;
- determine, based on a position of the input color value from each node of the set of nodes, a corresponding probability associated with each node of the set of nodes;
- and
- control, based on the determined probability associated with each node of the set of nodes, the operation of the thermal printhead.
