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 overlaying 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, overlaying conflicts between the graphics image and an alphanumeric character added by the operator are resolved in favor of the alphanumeric character. When an overlaying 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: 7
Claim 1
Independent Claim
195 words
A word processing system having an interactive display terminal for displaying alphanumeric and calculated graphic images while maintaining the integrity of the calculated graphic data comprising: first storage means for storing data representative of calculated graphic data; second storage means for storing alphanumeric character data entered by a user; merging means connected to said first and second storage means for merging the data in said first and second storage means for display on said display terminal; detecting means in said merging means for detecting overlaying conflicts between the merged data by resolving said overlaying conflicts in favor of the data from said second storage means while preserving the data in said first storage means, whereby erasure of conflicting data in said second storage means results in the display of data from said first storage means previously in overlaying conflict with data erased from said second storage means, said detecting means providing an output indicating an overlaying conflict between the data in said first and second storage means; and means responsive to said detecting means output for causing the corresponding data from said second storage means to be highlighted in its display on said display terminal.
Claim 2
Dependent Claim
195 words
A word processing system having an interactive display terminal for displaying alphanumeric and calculated graphic images while maintaining the integrity of the calculated graphic data comprising: first storage means for storing data representative of calculated graphic data; second storage means for storing alphanumeric character data entered by a user; merging means connected to said first and second storage means for merging the data in said first and second storage means for display on said display terminal; detecting means in said merging means for detecting overlaying conflicts between the merged data by resolving said overlaying conflicts in favor of the data from said second storage means while preserving the data in said first storage means, whereby erasure of conflicting data in said second storage means results in the display of data from said first storage means previously in overlaying conflict with data erased from said second storage means, said detecting means providing an output indicating an overlaying conflict between the data in said first and second storage means; and means responsive to said detecting means output for causing the corresponding data from said second storage means to be highlighted in its display on said display terminal.
Claim 3
Dependent Claim
147 words
The word processing system according to claim 1 wherein said word processing system further includes a printer, at least said display terminal being a character box device, said word processing system further comprising: third storage means for storing data representative of high resolution printed graphics in the form of a bit array; calculating means connected to said third storge means for calculating the data in said first storage means at a lower resolution compatible with said character box device from the data in said third storage means; second merging means connected to said second and third storage means for merging the data in said second and third storage means to produce a printer data stream; and second detecting means in said second merging means for detecting any overlaying conflicts between the data and resolving detected overlaying conflicts in favor of the data in said second storage means.
Claim 4
Independent Claim
176 words
A method of displaying images of alphanumeric data entered by a user and calculated graphic data on a display terminal while maintaining the integrity of the claculated graphic data comprising the steps of: storing said calculated graphic data; storing said alphanumeric character data as it is entered by a user; merging the stored calculated graphic data with the stored alphanumeric character data; detecting overlaying conflicts between the calculated graphic data and the stored alphanumeric character data merged in said merging step; displaying images of the merged calculated graphic data and alphanumeric character data while resolving detected overlaying conflicts between said calculated graphic data and said alphanumeric character data in favor of said alphanumeric character data for purposes of displaying said images; if conflicting alphanumeric character data is erased, then displaying the calculated graphic data image; detecting during said merging step overlaying conflicts between said calculated graphic data and said alphanumeric character data; and highlighting the displayed alphanumeric character data detected to conflict with stored calculated graphic data to show the user where an overlaying conflict exists.
Claim 5
Independent Claim
176 words
A method of displaying images of alphanumeric data entered by a user and calculated graphic data on a display terminal while maintaining the integrity of the claculated graphic data comprising the steps of: storing said calculated graphic data; storing said alphanumeric character data as it is entered by a user; merging the stored calculated graphic data with the stored alphanumeric character data; detecting overlaying conflicts between the calculated graphic data and the stored alphanumeric character data merged in said merging step; displaying images of the merged calculated graphic data and alphanumeric character data while resolving detected overlaying conflicts between said calculated graphic data and said alphanumeric character data in favor of said alphanumeric character data for purposes of displaying said images; if conflicting alphanumeric character data is erased, then displaying the calculated graphic data image; detecting during said merging step overlaying conflicts between said calculated graphic data and said alphanumeric character data; and highlighting the displayed alphanumeric character data detected to conflict with stored calculated graphic data to show the user where an overlaying conflict exists.
Claim 6
Dependent Claim
87 words
The method according to claim 3 wherein the step of displaying is performed on a character box display device and wherein the step of storing said calculated graphic data is performed by storing said calculated graphic data in high resolution in the form of a bit array and further comprising the step of deriving a lower resolution version of said calculated graphic data which is compatible with said character box display device, said lower resolution version being merged with said alphanumeric character data in said merging step.
Claim 7
Dependent Claim
70 words
The method according to claim 4 further comprising the steps of: merging said stored alphanumeric character data with the data in said bit array to generate a printer data stream by resolving overlaying conflicts between said stored alphanumeric character data with the data in said bit array in favor of said alphanumeric character data; and printing images of the merged alphanumeric character data and the data in said bit array.
