Abstract

Abstract A word processing system is provided with separate data structures in system memory (4). One of these, the internal image, contains the calculated graphics image and another the operator's alphanumeric character input. When displaying, the two images are merged together with the annotation overlay effectively overlying the graphics overlay. In this way, if the operator erases something on the annotation overlay, the contents of the graphics overlay reappear. During the display of the calculated image and as the operator adds annotations to the display, conflicts between the graphics image and an alphanumeric character added by the operator are resolved in favor of the alphanumeric character. When a conflict does exist, the alphanumeric character is highlighted by video reversing to indicate that it is hiding a portion of the graphics image.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 125 words
In a word processing system having an interactive display terminal, the improvement comprising apparatus for displaying alphanumeric and calculated graphic images on said display terminal while maintaining the integrity of the calculated graphic data, said apparatus being characterized in that it includes : - first storage means for storing data representative of calculated graphic data, - second storage means for storing alphanumeric character data entered by a user, and - means merging the data in said first and second storage means for display on said display terminal with conflicts between the data being resolved in favor of the data from said second storage means, whereby erasure of conflicting data in said second storage means results in the display of data from said first storage means.
Claim 2
Dependent Claim 125 words
In a word processing system having an interactive display terminal, the improvement comprising apparatus for displaying alphanumeric and calculated graphic images on said display terminal while maintaining the integrity of the calculated graphic data, said apparatus being characterized in that it includes : - first storage means for storing data representative of calculated graphic data, - second storage means for storing alphanumeric character data entered by a user, and - means merging the data in said first and second storage means for display on said display terminal with conflicts between the data being resolved in favor of the data from said second storage means, whereby erasure of conflicting data in said second storage means results in the display of data from said first storage means.
Claim 3
Dependent Claim 109 words
Apparatus according to claim 1 wherein said word processing system further includes a printer, at least said display terminal being a character box device, said apparatus further comprising : - third storage means for storing data representative of high resolution printed graphics in the form of a bit array, the graphic data in said first storage means being of lower resolution and calculated from the data in said third storage means, and - means for merging the data in said second and third storage means to produce a printer data stream with any conflicts between the data being resolved in favor of the data in said second storage means.
Claim 4
Dependent Claim 58 words
Apparatus according to claim 1 or 2 wherein said means for merging includes means for detecting a conflict between the data in said first and second storage means, said apparatus further comprising means responsive to said detecting means for causing the corresponding data from said second storage means to be highlighted in its display on said display terminal.
