  • Publication number: 20170193117
    Abstract: A method of searching one or more content items from a web service is disclosed. The method includes loading a search application embedded on a client page and associating the search application with the web service. A filter panel is configured to display one or more web service parameters for use in searching for the one or more content items from the web service. The values corresponding to each of the one or more web service parameters is retrieved and a search query string is generated using a URL of the web service and the values corresponding to each of the one or more web service parameters. The method further includes sending the search query string to the web service, receiving a response from the web service, and configuring a results panel that includes a list of content items corresponding to the response.

  • Publication number: 20090135439
    Abstract: A method of printing a high resolution image with a printhead in a multi-pass printing mode includes subdividing the high resolution image into a plurality of low resolution sub-images; subdividing each low resolution sub-image into a plurality of low resolution swath portions; and allocating an amount of a memory for buffer storage, the amount being only sufficient to store data corresponding to less than two of the low resolution swath portions. The method also includes, for each low resolution swath portion: halftoning each low resolution swath portion to generate a corresponding halftoned low resolution swath portion, the halftoning of each low resolution swath portion of a particular low resolution sub-image being performed independently of halftoning the low resolution swath portions of other low resolution sub-images; storing the halftoned low resolution swath portion into the amount of the memory; and printing the halftoned low resolution swath portion.

  • Patent number: 7425054
    Abstract: Disclosed is a method for printing swaths of an image in an inkjet printer with reduced memory usage for delay buffer. The present invention provides methods for allocating a memory space of M1, and M2, for the delay buffer, where M1 equals N*S*(P+1)/2, and M2 equals N*S*(P?1)/2, wherein N is the number of nozzles in a color bank of a printhead, S is the horizontal swath resolution and P is the minimum number of pass required to print the image. The proposed methods lower the hardware requirement of the physical memory by saving up to about 50% of the physical memory by implementing a memory space of M1 and more than 50% of physical memory may be saved by implementing a memory space of M2.
