Abstract
Abstract To process the layout of graphical objects, elastics data structures are established for the graphical objects to define minimum and preferred sizes, stretch properties and compression properties. Composite graphical objects include elastics properties computed from their components through add and max operations which are dependent on relative elasticities of the components. The positions of origins within graphical objects are defined by pairs of elastics in each of two dimensions. One application of elastics is with respect to text blocks where preferred width and compressibility of each text block is a function of the amount of text in the text block. The elastics and dimensions of graphical objects are processed in a three pass layout negotiation. In the first pass, preferred sizes and elasticities of the graphical objects are computed along a first dimension. In a second pass, size values of the graphical objects along the first dimension are computed from the preferred sizes and elasticities, and preferred sizes and elasticities of the graphical objects along a second dimension are computed based on the size values of the graphical objects along the first dimension. In a final pass, size values of the graphical objects along the second dimension are computed from the preferred sizes and elasticities.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
71 words
A method of processing plural blocks of text to lay out the text comprising: defining a preferred width and compressibility of each block of text as a function of the amount of text in the block of text; defining a stretchiness to each block of text distinct from the compressibility; and processing the widths and compressibilities of the blocks of text to define an overall layout of the blocks of text.
Claim 2
Independent Claim
71 words
A method of processing plural blocks of text to lay out the text comprising: defining a preferred width and compressibility of each block of text as a function of the amount of text in the block of text; defining a stretchiness to each block of text distinct from the compressibility; and processing the widths and compressibilities of the blocks of text to define an overall layout of the blocks of text.
Claim 3
Dependent Claim
19 words
A method as claimed in claim 1 wherein the stretchiness of the text is substantially greater than its compressibility.
Claim 4
Dependent Claim
42 words
A method as claimed in claim 2 wherein stretchiness is defined by a stretch order and stretchiness coefficient and compressibility is defined by a compress order and compressibility coefficient and the stretch order of the text is greater than the compressibility order.
Claim 5
Dependent Claim
29 words
A method as claimed in claim 1 further comprising defining a preferred size of each block of text to lay out the text in a minimal number of lines.
Claim 6
Dependent Claim
20 words
A method as claimed in claim 4 wherein a compressibility coefficient is defined to be proportional to a text length.
Claim 7
Dependent Claim
19 words
A method as claimed in claim 5 wherein the stretchiness of the text is substantially greater than its compressibility.
Claim 8
Dependent Claim
42 words
A method as claimed in claim 6 wherein stretchiness is defined by a stretch order and stretchiness coefficient and compressibility is defined by a compress order and compressibility coefficient and the stretch order of the text is greater than the compressibility order.
Claim 9
Dependent Claim
79 words
A data structure in a data processing system defining a block of text comprising: text data; a preferred width of the text data; a compressibility property for the width of the text data, the preferred width and the compressibility property of the block of text defined as a function of the amount of the text data in the block of text; and a stretchiness property for the width of the text data which is distinct from the compressibility property.
Claim 10
Dependent Claim
79 words
A data structure in a data processing system defining a block of text comprising: text data; a preferred width of the text data; a compressibility property for the width of the text data, the preferred width and the compressibility property of the block of text defined as a function of the amount of the text data in the block of text; and a stretchiness property for the width of the text data which is distinct from the compressibility property.
Claim 11
Dependent Claim
20 words
A data structure as claimed in claim 8 wherein the stretchiness of the text is substantially greater than its compressibility.
Claim 12
Dependent Claim
43 words
A data structure as claimed in claim 9 wherein stretchiness is defined by a stretch order and stretchiness coefficient and compressibility is defined by a compress order and compressibility coefficient and the stretch order of the text is greater than this compressibility order.
Claim 13
Dependent Claim
30 words
A data structure as claimed in claim 8 further comprising defining a preferred size of each block of text to lay out the text in a minimal number of lines.
Claim 14
Dependent Claim

Claim 16
Dependent Claim
43 words
A data structure as claimed in claim 13 wherein stretchiness is defined by a stretch order and stretchiness coefficient and compressibility is defined by a compress order and compressibility coefficient and the stretch order of the text is greater than this compressibility order.
