Abstract

Disclosed herein are embodiments of systems and methods for displaying and updating image previews in the graphical user interface of an application program. The image previews for a given master image within the application program constitute various image sizes and resolutions of that master image, and are preferably compiled as image preview data sets in a database. When the image previews are manipulated in the application program an appropriate resolution for that image preview can be queried from the database and displayed. For example, while scrolling, a lower-resolution image preview data set might he used when compared to image preview data sets used while the image previews are not scrolled, thus making them less computationally intensive to display and update. Likewise, while magnifying, an appropriate image preview data set can be queried from the database instead of, or in conjunction with, up or downscaling the image preview.

Dependent claims

A non-transitory program storage device, readable by a processor and comprising instructions stored thereon to cause the processor to:

store, to persistent storage, three or more image previews for each of at least one image, wherein the image previews for each of the images are all of differing pixel resolutions and wherein an image preview comprises a representation of its corresponding image and wherein a data format of at least two of the three or more image previews are different from each other;
receive an indication of a magnification level for presentation of the at least one image;
determine characteristics of the indication of the magnification level;
identify which of the three or more image previews' data formats represent a more efficient preview to use based on the characteristics of the indication of the magnification level;
select, based on the identification, one of the three or more image previews to correspond to one of a plurality of magnification levels for the at least one image;
retrieve, from the persistent storage, one of the three or more image previews in accordance with the selected image preview and indicated magnification level;
and
display the at least one image in a graphical user interface.
