字体渲染方法、装置及计算机可读存储介质 技术领域
本发明涉及文字处理技术领域，具体而言，涉及一种字体渲染方法，一种字体渲染装置，及一种计算机可读存储介质。
背景技术
传统的文字排版方式就是从左至右、从上到下、行间距、列间距固定模式，不够有创意、页面效果过于单调；表情展示字体只能是固定字，而且需要前期制作好，不能根据用户输入即时呈现效果；复制图片表情的时候无法对提取出汉字；此外，市面上的绘制方式都是通过上层或者CPU(Central Processing Unit，中央处理器)的方式来绘制，由于运算量大，不适合在低性能终端设备上使用，也做不出来效果比较酷炫的效果。
发明内容
本发明旨在至少解决现有技术或相关技术中存在的技术问题之一。
为此，本发明的一方面在于提出了一种字体渲染方法。
本发明的另一方面在于提出了一种字体渲染装置。
本发明的再一方面在于提出了一种计算机可读存储介质。
有鉴于此，本发明提出了一种字体渲染方法，包括：接收需要渲染的字符串，读取字体文件；解析字体文件，获得字符串对应的文字字形信息与模板信息；根据文字字形信息与模板信息生成动画单元；对动画单元进行渲染。
根据本发明的字体渲染方法，接收需要渲染的字符串，例如从客户端接收用户输入的字符串，读取字体文件如动态嗨爆TTF(TrueTypeFont)字库文件，对该字体文件进行解析，获得字符串对应的文字字形信息与模板信息，将文字字形信息与模板信息进行融合，生成动画单元，其中动画的频率可以是固定的帧间隔或者不规律帧间隔，再对动画单元进行渲染，渲染后输出进行效果呈现。通过本发明的字体渲染方法，可以根据不同的字体效果，不同的行列来自定义对应的模板效果，支持文字大小混排、自 定义文字位置、自定义文字颜色与特效、更适合场景搭配与图文结合，从而更充分地表达语义主次，增强文字视觉冲击力，突显语言重心，彰显文字意境，并且可根据用户输入即时呈现任意不同风格的个性化效果，极大满足了用户在信息交互时的个性化需求。

本发明实施例提供的字体渲染方法，打破了传统从左至右，从上到下，行间距，列间距固定排版模式，支持文字大小混排，更充分地表达语义主次；支持自定义文字位置，增强文字视觉冲击力；支持任意文字颜色与特效的定义，突显语言重心；具有设计感更适合场景搭配与图文结合，彰显文字意境；同时用户输入即时呈现效果，用户可根据自己想表达的内容任意输入文字，就可以得到根据文字数量对应的模板生成一个动态嗨爆效果；用户可以复制已经呈现出来的动态嗨爆效果，粘贴后还原成之前输入的文字，然后根据自己的需要重新进行编辑或者粘贴到记事本等，进一步 进行文字处理。此外，基于OpenGL技术的GPU渲染，提高了渲染速度，节省了系统资源的消耗，保证了系统的流畅性，对用户有很好的流畅度体验，并适用于低性能终端，进一步提高了用户的体验。
本发明实施例还提供了一种计算机可读存储介质，包括：如上述实施例中任一项的字体渲染装置。
本发明实施例的计算机可读存储介质，包括如上述实施例中任一项的字体渲染装置，因而具有该字体渲染装置全部的有益效果，不再赘述。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
