Abstract

A method of cropping a digital image and preserving a reserve for subsequent use includes cropping the digital image to produce a first cropped digital image, the first cropped digital image having a first size and a first aspect ratio; determining, based on the location of the cropping, at least one reserve portion of the image adjacent to at least one edge of the first cropped digital image; and storing, in an image file, the first cropped digital image and the reserve(s).

Claims

1. A method of cropping a digital image and preserving a reserve for subsequent use comprising:

(a) cropping the digital image to produce a first cropped digital image, the first cropped digital image having a first size and a first aspect ratio;

(b) determining, based on the location of the cropping, at least one reserve portion of the image adjacent to at least one edge of the first cropped digital image; and

(c) storing, in an image file, the first cropped digital image and the reserve(s).

2. The method of claim 1 wherein the digital image is cropped in accordance with a preselected aspect ratio.

3. The method of claim 1 wherein the digital image is cropped in accordance with a user selected aspect ratio.

4. The method of claim 1 wherein the first cropped digital image is stored as a JPEG compressed main image.

5. The method of claim 4 wherein the reserve(s) are stored in at least one application segment.

6. The method of claim 1 wherein the cropping is rectangular and reserve portions correspond to different edges of the cropped digital image.

7. A method for producing a second cropped digital image using the image file produced by the method of claim 1, comprising:

(a) retrieving the cropped digital image from the image file; and

(b) appending at least a portion of at least one reserve to the cropped digital image to produce the second cropped digital image, the second cropped digital image having a second aspect ratio different than the first aspect ratio.

8. A method for producing a second cropped digital image using the image file produced by the method of claim 1, comprising:

a) retrieving the cropped digital image from the image file; and

b) appending at least a portion of at least one reserve to the cropped digital image to produce the second cropped digital image, the second cropped digital image having a second size different than the first size.

9. A digital image file produced by the method of claim 1.

10. The method of claim 1 wherein the edge is a vertical edge, and wherein the width of the reserve portion of the image adjacent to the vertical edge is calculated by multiplying the height of the first cropped digital image by a maximum aspect ratio value and subtracting the width of the first cropped digital image.

11. A digital image file associated with a cropped version of an original digital image, comprising:

(a) a cropped digital image; and

(b) at least one reserve portion of the original image, the reserve portion being a portion of the original digital image adjacent to the cropped digital image.

12. The digital image file of claim 11 wherein the cropped digital image is stored as a JPEG compressed main image.

13. The digital image file of claim 12 wherein the reserve(s) are stored in at least one application segment.

14. The digital image file of claim 11 wherein the width of the reserve portion of the image adjacent to a vertical edge of the cropped digital image is equal to the height of the cropped digital image times a maximum aspect ratio value minus the width of the cropped digital image.
