Description
Technical field
It is the present invention relates to planar design technology field, in particular to a kind of based on text paragraph structure and font size change rate
Autoplacement device.
Background technique
When carrying out planar design, designer's common practice is to use a Background as background, is then looked for
Then the foreground area of this back out places logo, decoration or text in these foreground areas.
These regions for being used to place text are referred to as " block " by we.Such as: with red dotted box mark in poster
Region out is exactly " block ", and there are four " blocks " altogether in this poster.These " blocks " need a layout, so as to than
Text is more aesthetically put into these regions.
Currently, the identification of the background and foreground area of a picture passes through these algorithms with the presence of a large amount of algorithm
It can identify " block ".But the autoplacement of content in " block " is still solved the problems, such as without good algorithm.If this
Problem is available preferably to be solved, and automatically generates such planar design then can realize along this thinking.
The present apparatus proposes a kind of autoplacement device based on text paragraph structure and font size change rate, may be implemented
The autoplacement of word content in " block " has established certain basis for intelligent automation planar design.
Summary of the invention
Therefore, for above-mentioned problem, the present invention proposes a kind of automatic based on text paragraph structure and font size change rate
Placement device, by the autoplacement device based on text paragraph structure and font size change rate, needs are laid out by user
Text carries out the confirmation of priority division and " block " size, so generates several layout trees, and the grid in layout tree can basis
The change rate of text changes automatically, therefore does not need designer and repeat adjustment lattice dimensions, to substantially reduce the repetition of designer
Work removes the trouble of repetition adjustment size and parameter from, improves out figure efficiency.
To realize above-mentioned technical problem, the solution that the present invention takes are as follows: one kind is based on text paragraph structure and font size
The autoplacement device of change rate, which is characterized in that including layout generator；The autoplacement method of the layout generator is such as
Under:
Step (1) user carries out preferentially content to the customized input content of layout generator, while according to content design intention
Grade setting, the priority level initializing rule are since P0, and number is smaller, represents that priority is higher, and the priority represents
The relative size of text font size in grid, the high content of priority are bound to the font size bigger using the content lower than priority.
Step (2) layout generator generates layout tree to content according to priority level initializing, wherein the tree node of layout tree
Grid is corresponding with priority-level to be generated；User can rotate the layout tree tree node of generation, adjust, and obtain different
Layout.
After step (3) layout tree generates, specific lattice dimensions, the ruler for drawing grids are obtained according to the algorithm flow of grid
Very little calculation method includes following process:
An initial size range S is arranged to P0 in process (1)a~Sb。
The font size value S that P0 is arranged in process (2) is Sb；
Process (3) calculates the font size value of different priorities according to the font size value and font size change rate function of P0；
Each grid is placed word content as independent one big section, according to process (3) by process (4)；Difference is calculated
Then the font size of priority puts these texts together, trial places them into " block ", is recycled according to result is put into
It calculates, the circulation is as follows:
1. whole texts can be put into, and the area of remaining space is less than or equal to the k% of " block " gross area, then jumping to
Process (5).
2. whole texts can be put into, and the area of remaining space is greater than the k% of " block " gross area, S is modifiedaValue
For (Sb+Sa)/2 are rounded downwards, then branch to process (3)；
3. can not be put into whole texts, the value for modifying Sb is (Sb+Sa)/2 round up, and then branch to process (3)；
4. the font size of the condition of satisfaction can not be found, after whole texts can be put by selection, the area accounting of remaining space is most connect
The font size of nearly k% is as calculated result；
Process (5) is accounted for according to the typesetting in process (4) as a result, calculating space of the text corresponding to each grid in " block "
Than.
The corresponding font size size of each priority and accounting of each grid in " block " are obtained according to above-mentioned process, most
Lattice dimensions are obtained eventually.
Further, the font size change rate functional relation includes:
Power function: f(x)=mxa, wherein m and a is empirical coefficient；
Exponential function: f(x)=lbx, wherein l and b is empirical coefficient；
Logarithmic function: f (x)=clog (x), wherein c is empirical coefficient.
By using preceding solution, the beneficial effects of the present invention are: being based on text paragraph structure and word as described above
The autoplacement device of number change rate, client can first determine the size of one " block ", later can be according to the demand pair of client
Text paragraph carries out priority distribution, selects distribution form further according to the hobby of oneself after distributing, at this time the grid in layout tree
Lattice will will do it automatic variation, solve the current text layout that changes and need to carry out cumbersome operation, so that the work of designer
The problem of decreasing efficiency.
Detailed description of the invention
Fig. 1 is the algorithm flow chart of lattice dimensions of the present invention.
Specific embodiment
Now in conjunction with the drawings and specific embodiments, the present invention is further described.
