Dynamic adjustment of select elements of a document
Technologies are described herein for providing dynamic adjustment of select elements of a document. In some configurations, when a command for scaling a document is received, technologies described herein selectively resize elements of the document and then apply a rendering scale factor to the document. For example, a computing device may render a document having an element, such as a table, and other elements, such as text and images. Upon receiving a command to apply a rendering scale factor to the document, techniques herein determine at least one dimension of the element based on the rendering scale factor. The document including the element with the at least one dimension is then rendered based on the rendering scale factor. By dynamically adjusting one or more dimensions of select elements, the layout of the document may be preserved even when a user zooms into or out of the document.
1. A computer-implemented method, the method comprising:
rendering, at a computing device, a document including a formatting element and text arranged within a boundary of the formatting element, wherein the boundary maintains the text within a viewing area of a display device;
receiving a command to apply a first scale factor to the text of the document;
determining at least one dimension of the boundary of the formatting element of the document based on a second scale factor that is based on an inverse of the first scale factor;
rendering the document, wherein the text is rendered based on the first scale factor, and wherein the at least one dimension of the boundary is rendered based on the second scale factor that is based on the inverse of the first scale factor, wherein a magnitude of the second scale factor is adjusted above the inverse of the first scale factor based on an increase of a magnitude of the first scale factor, and wherein the boundary is rendered to maintain the text within the viewing area of the display device; and
in response to the rendering of the document, displaying the text without requiring a user to scroll horizontally or vertically to view the rendered text.
2. The computer-implemented method of claim 1 , wherein determining the at least one dimension comprises:
determining contextual information associated with the formatting element;
determining a weight that is based on the contextual information and the inverse of the rendering scale factor; and
determining the at least one dimension of the boundary of the formatting element based on the weight.
3. The computer-implemented method of claim 1 , wherein the document comprises an image, and wherein rendering the document comprises:
determining contextual information associated with content of the image;

determining a weighted rendering scale factor based on the rendering scale factor and the contextual information associated with the image; and
applying the weighted rendering scale factor to the image.
5. The computer-implemented method of claim 1 , wherein the document comprises a first image and a second image, and wherein rendering the document comprises:
determining contextual information associated with the first image;
determining contextual information associated with the second image;
applying the rendering scale factor to the first image based on the contextual information associated with the first image; and
applying a weighted rendering scale factor to the second image based on the contextual information associated with the second image.
6. A computer, comprising:
a processor; and
a computer-readable storage medium in communication with the processor, the computer-readable storage medium having computer-executable instructions stored thereupon which, when executed by the processor, cause the computer to
render a document including a formatting element and text arranged within a boundary of the formatting element, wherein the boundary maintains the text within a viewing area of a display device,
receive a command to apply a first scale factor to the text of the document,
determine at least one dimension of the boundary of the formatting element based on a second scale factor that is based on an inverse of the first scale factor,
render the document, wherein the text is rendered based on the first scale factor, and wherein the at least one dimension of the boundary is rendered based on the second scale factor that is based on the inverse of the first scale factor, wherein a magnitude of the second scale factor is adjusted above the inverse of the first scale factor based on an increase of a magnitude of the first rendering scale factor, and wherein the boundary is rendered to maintain the text within the viewing area of the display device; and
in response to the rendering of the document, display the text without requiring a user to scroll horizontally to view the rendered text.
7. The computer of claim 6 , wherein the formatting element comprises a frame around the text of the document.
8. The computer of claim 6 , wherein the formatting element comprises a table around the text of the document.
9. The computer of claim 6 , wherein determining the at least one dimension comprises:
determining contextual information associated with the formatting element;
determining a weight that is based on the contextual information and the inverse of the rendering scale factor; and
determining the at least one dimension of the boundary of the formatting element based on the weight.
10. The computer of claim 6 , wherein the document comprises an image, and wherein rendering the document utilizing the at least one dimension associated with the at least one element, comprises:
determining contextual information associated with the image;
determining if the rendering scale factor is to be applied to the image based on the contextual information; and
applying the rendering scale factor to the image if it is determined that the rendering scale factor is to be applied to the image.
11. The computer of claim 6 , wherein the document comprises an image, and wherein rendering the document utilizing the at least one dimension associated with the at least one element, comprises:
determining contextual information associated with the image;
determining a weighted rendering scale factor based on the rendering scale factor and the contextual information associated with the image; and
applying the weighted rendering scale factor to the image.
12. The computer of claim 6 , wherein the document comprises a first image and a second image, and wherein rendering the document utilizing the at least one dimension associated with the at least one element, comprises:
determining contextual information associated with the first image;
determining contextual information associated with the second image;
applying the rendering scale factor to the first image based on the contextual information associated with the first image; and
applying a weighted rendering scale factor to the second image based on the contextual information associated with the second image.
13. A computer-readable storage medium having computer-executable instructions stored thereupon which, when executed by a computer, cause the computer to:
render a document including a formatting element and text arranged within a boundary of the formatting element, wherein the boundary maintains the text within a viewing area of a display device;
receive a command to apply a first scale factor to the text of the document;
