Thumbnail image virtual address space
A method includes loading a plurality of thumbnail images into a virtual address space having a first address, and retrieving a specific thumbnail image of the plurality of thumbnail images from the virtual address space by indexing into the virtual address space at a location defined by an offset, the offset corresponding to the specific thumbnail image.
1. A method including:
creating a first thumbnail image from an original image, the original image being unrecoverable from the first thumbnail image;
loading a plurality of thumbnail images including the first thumbnail image, into a virtual address space having a first address;
retrieving thumbnail images associated with items for sale, the thumbnail images created based on images retrieved from a plurality of sites; and
retrieving a specific thumbnail image of the plurality of thumbnail images from the virtual address space by indexing into the virtual address space at a location defined by an offset, the offset corresponding to the specific thumbnail image.
2. The method of claim 1 , wherein the loading of the plurality of thumbnail images comprises loading a database including the plurality of thumbnail images into the virtual address space.
3. The method of claim 2 , wherein the loading of the plurality of thumbnail images comprises opening the database as a memory mapped file.
4. The method of claim 3 , wherein each entry within the database includes a length field and image data for a respective thumbnail image.
5. The method of claim 1 , wherein the virtual address space is a continuous virtual address space.
6. A system including:
first means for creating a first thumbnail image from an original image, the original image being unrecoverable from the first thumbnail image;
second means for loading a plurality of thumbnail images including the first thumbnail image, into a virtual address space having a first address;
third means for retrieving thumbnail images associated with items for sale, the thumbnail images created based on images retrieved from a plurality of sites; and
fourth means for retrieving a specific thumbnail image of the plurality of thumbnail images from the virtual address space by indexing into the virtual address space at a location defined by an offset, the offset corresponding to the specific thumbnail image.
7. The system of claim 6 , wherein the first means is for loading a database including the plurality of thumbnail images into the virtual address space.
8. The system of claim 7 , wherein the first means is for opening the database as a memory mapped file.
9. The system of claim 8 , wherein each entry within the database includes a length field and image data for a respective thumbnail image.
10. The system of claim 6 , wherein the virtual address space is a continuous virtual address space.
11. A tangible machine-readable medium comprising instructions, which when implemented by one or more processors perform the following operations:
creating a first thumbnail image from an original image, the original image being unrecoverable from the first thumbnail image;
loading a plurality of thumbnail images including the first thumbnail image, into a virtual address space having a first address;
retrieving thumbnail images associated with items for sale, the thumbnail images created based on images retrieved from a plurality of sites; and
retrieving a specific thumbnail image of the plurality of thumbnail images from the virtual address space by indexing into the virtual address space at a location defined by an offset, the offset corresponding to the specific thumbnail image.
