Abstract
Abstract Clipping individual rows or columns of pels from patterns stored as pels is accomplished by passing quads of pels through a clipper before rotation is effected. Integral numbers of quads are clipped by skipping their address when reading from the pattern store or inhibiting their transfer. This permits more detailed pages to be composed for printing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
A system for selectively moving prestored image patterns or segments thereof to construct an image, said image being composed in an image storage means for displaying/printing as pels comprising: pattern storage means for storing individual patterns in the forms of pels; first addressing means for retrieving from said pattern storage means quads of pels comprising a selected a pattern; transfer means for moving said quads of pels to said image storage means, said transfer means including, means for selectively removing a single row or column of original image pels from an edge of a quad being moved, and means for rotating said quads of pels; and second addressing means for supplying addresses in the image storage means at which said quads from said transferring means are stored to compose the image to be printed.
Claim 2
Independent Claim
134 words
A system for selectively moving prestored image patterns or segments thereof to construct an image, said image being composed in an image storage means for displaying/printing as pels comprising: pattern storage means for storing individual patterns in the forms of pels; first addressing means for retrieving from said pattern storage means quads of pels comprising a selected a pattern; transfer means for moving said quads of pels to said image storage means, said transfer means including, means for selectively removing a single row or column of original image pels from an edge of a quad being moved, and means for rotating said quads of pels; and second addressing means for supplying addresses in the image storage means at which said quads from said transferring means are stored to compose the image to be printed.
Claim 3
Dependent Claim
51 words
The system as claimed in claim 1 wherein said means for selectively removing a single row or column of original image pels comprises: means for generating control signals; and gating means controlled by said control signals for selectively gating signals representing said pels to be stored in the image storage means.
Claim 4
Dependent Claim
26 words
The system claimed in claim 1 wherein said means for rotating said quads of pels includes means for multiplexing signals representing said pels to be rotated.
Claim 5
Dependent Claim
117 words
In a system for displaying images in the form of dots, including means for prestoring patterns as rectangular groups of dots, means for cumulating an image to be displayed, and means for transferring selected prestored patterns into said cumulating means, the improvement comprising: clipping means included in said transferring means for selectively removing single rows or single columns of dots of original image information from certain patterns or rectangular groups of dots being transferred; and, means for rotating patterns being transferred, said rotating means including address control means for addressing said groups of dots of a prestored pattern in a selected sequence, and means for changing the sequence of dots in a group of dots being transferred.
Claim 6
Dependent Claim
117 words
In a system for displaying images in the form of dots, including means for prestoring patterns as rectangular groups of dots, means for cumulating an image to be displayed, and means for transferring selected prestored patterns into said cumulating means, the improvement comprising: clipping means included in said transferring means for selectively removing single rows or single columns of dots of original image information from certain patterns or rectangular groups of dots being transferred; and, means for rotating patterns being transferred, said rotating means including address control means for addressing said groups of dots of a prestored pattern in a selected sequence, and means for changing the sequence of dots in a group of dots being transferred.
Claim 7
Dependent Claim
21 words
The system claimed in claim 4 further including, in said rotating means, means for indicating the orientation of the prestored patterns.
