Abstract
Abstract The invention relates to a method and apparatus for adjusting the text height within a displayed image. A preferred absolute text height is input to the computer system by a user and is stored. When text images are displayed by the computer system, a selected section of text is determined. The stored preferred absolute text height is then retrieved, and the displayed text images are scaled by a scale factor such that the selected text section is displayed at the preferred absolute text height.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
106 words
A computer system for scaling a raster image, the system comprising: a digital processing apparatus; a display coupled to said digital processing apparatus for displaying a raster image including text; a means for retrieving a preferred absolute text height stored by the digital processing apparatus; a means for selecting a block of text to adjust to the selected preferred absolute text height; and means for adjusting the entire raster image by an amount which adjusts the selected block of text to the preferred absolute text height and for adjusting the height of the text in the remainder of the raster image proportionately by the same amount.
Claim 2
Dependent Claim
106 words
A computer system for scaling a raster image, the system comprising: a digital processing apparatus; a display coupled to said digital processing apparatus for displaying a raster image including text; a means for retrieving a preferred absolute text height stored by the digital processing apparatus; a means for selecting a block of text to adjust to the selected preferred absolute text height; and means for adjusting the entire raster image by an amount which adjusts the selected block of text to the preferred absolute text height and for adjusting the height of the text in the remainder of the raster image proportionately by the same amount.
Claim 3
Dependent Claim
21 words
A computer system as recited in claim 1 wherein the means for selecting a block of text includes a user-controlled cursor.
Claim 4
Dependent Claim
21 words
A computer system as recited in claim 2 wherein a position of said user-controlled cursor is controlled by a pointing device.
Claim 5
Independent Claim
106 words
A method for displaying a preferred size of text on a display device of a computer system, the method comprising: displaying text having a plurality of heights on a display device; selecting a subset of the displayed text, all of which has a single text height; retrieving a different preferred text height stored by the computer system for the selected subset of text; adjusting the height of all displayed text including the selected subset and the remainder of displayed text by a ratio between the different preferred text height and the single text height; and re-displaying the text on the display device at the adjusted height.
Claim 6
Independent Claim
106 words
A method for displaying a preferred size of text on a display device of a computer system, the method comprising: displaying text having a plurality of heights on a display device; selecting a subset of the displayed text, all of which has a single text height; retrieving a different preferred text height stored by the computer system for the selected subset of text; adjusting the height of all displayed text including the selected subset and the remainder of displayed text by a ratio between the different preferred text height and the single text height; and re-displaying the text on the display device at the adjusted height.
Claim 7
Dependent Claim
28 words
A method as recited in claim 4 wherein the step of selecting a subset of the displayed text includes the use of a cursor controlled by a user.
Claim 8
Dependent Claim
18 words
A method as recited in claim 4 wherein said preferred text height is retrieved from a storage device.
Claim 9
Dependent Claim
31 words
A method as recited in claim 6 further comprising a step of prompting a user to input said preferred text height, and storing said input text height on said storage device.
Claim 10
Dependent Claim
28 words
A method as recited in claim 7 wherein said step of prompting said user includes displaying a preferences window for a user to input said preferred text height.
Claim 11
Dependent Claim
33 words
A method as recited in claim 8 wherein said step of displaying a preferences window includes displaying example text in said preferences window corresponding to said preferred text height input by said user.
Claim 12
Dependent Claim
25 words
A method as recited in claim 5 wherein said step of adjusting the height of said text is performed when a scaling command is received.
