Embodiment Construction

[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0018] figure 1 Shows a flow chart of a method for controlling the scope of use of fonts according to an embodiment of the present invention, including:

[0019] Step S10, deforming the glyphs of the font using a deformation algorithm to obtain the deformed glyphs;

[0020] Step S20, generating a restoration instruction for restoring the deformed glyph according to the deformation algorithm, wherein specific conditions for normal restoration are set for the restoration instruction;

[0021] Step S30, adding the restoration instruction into the font library.

[0022] The prior art cannot control the range of use of the font, but in this embodiment, because the font is deformed and specific conditions for restoring the font are set, the problem that the prior art cannot control the range of use of the font can be solved by setting sp...

Abstract

The invention provides a method for controlling the serviceable range of a font library, which comprises the following steps: by using a transformation algorithm, transforming fonts of a font library to obtain transformed fonts; generating a reduction instruction for reducing the transformed fonts based on the transformation algorithm, wherein specific conditions for normal reduction are set for the reduction instruction; and adding the reduction instruction into the font library. The invention also provides a device for controlling the serviceable range of a font library, which comprises a transformation module, an instruction module and addition module, wherein the transformation module is used for transforming fonts of a font library to obtain transformed fonts based on the transformation algorithm; the instruction module is used for generating a reduction instruction for reducing the transformed fonts based on the transformation algorithm, and specific conditions for normal reduction are set for the reduction instruction; and the addition module is used for adding the reduction instruction into the font library. The invention protects the lawful rights and interests of the font library owner.

Description

technical field [0001] The invention relates to the field of digital typesetting, in particular to a method and a device for controlling the use range of a font library. Background technique [0002] TrueType is a font mathematical description technology jointly proposed by Apple Computer and Microsoft. TrueType uses quadratic B-spline curves and straight lines in geometry to describe the outline of fonts. Its characteristic is that TrueType can be used as both a printing font and a screen display. TrueType also provides operation instructions, and each operation instruction completes a single function. Operation instructions support loops, conditional branches, function calls, basic logic operations, and points in glyph outlines. The operation instruction can modify the glyph outline. [0003] Different output devices, resolutions and displayed font sizes vary widely. However, the TrueType font library supports almost all output devices, whether it is on a computer scre...
