Web图像不必要布局

写由基督教Nwamba客座作者

图像组成多数网络内容.但许多网站和应用程序我们浏览并非总能提供最优图像格式、大小、质量和维度.

开发者为二千千兆赫JPEG图像服务似乎效率低下,而我们可以压缩图像优化性能无损视觉质量

我们不是新人 负起这种责任但是,如果我们不快速交付,生产率最终会受到质询社区设计出几种模式帮助提高生产率少有这些模式基于类别

  • 优化格式
  • 第三方库
  • 第三方APIs

优化格式

自然使用图像格式如PNG、JPEG和GIF这三个问题相隔数年,但每个问题都有特征,在某些情况下会令你相互选择。引入额外格式并正在对其中一些格式实现标准化,以便提供更好的方法以最优化水平为图像服务

实例

  • WebP
  • JPEG-XR
  • BPG系统

最优化格式事实上是减少图像浮点的极佳尝试图像格式实现方便优化化压缩不使用第三方解决方案可惜图像格式战仍在继续,因为所有浏览器支持不足、限制、策略和其他因素难以确保每个图像格式均得到持续优化

第三方库

第三方库压缩图像数据库提供受暴露API方法,通过图像文件,指定压缩参数,并发回压缩图像配置

写自己的解决方案没有问题,但我们也在努力省时图书馆基于某些标准算法写作, 在一定程度上依赖这些算法是正常的但他们可能没有给你足够的弹性 处理压缩方式很难找到第三方库取PNG文件并交付最优压缩无损图像

第三方APIs

公共和溢价第三方API可用于处理发泡图像,并发回作为HTTP响应迄今最易使用,因为它只需要HTTP基本知识来压缩图像。贝斯特2200娱乐语言或平台依赖性不亚于其他人

实例:

外加,你遇到的问题与第三方SDKs相同:很难找到完全一解法足以解决你问题。

提供CDN的更好选择

贝斯特2200娱乐上文讨论平台常用压缩图像,但没有平台提供压缩优化综合智能解决方案图像传送和上传可能更加复杂化,需要时通过内容传送网络为图像服务(CDN)。增加问题复杂性的另一层

万一单项工具

  1. 上传、存储和通过CDN发送图像
  2. 变换图像(多色调等)
  3. 无损压缩图像

云化即解决之道综合图像管理工具 快速易处理图像问题 消除图像存储管理的挑战和风险

云化还智能处理图像压缩挑战图像变换特征提供图像质量控制,同时提供自动选择质量和格式的选项

云端最有意思的是所有这些特征都基于 URL,这意味着你只需要修改 URL实现你需要的配置sdks提供时,如果选择不操作 URL 操作,也可以使用 sdks

图像质量变换

浏览器,如Chrome支持特定格式,如WebP提高性能云人总知道时间和方式 并不会损及图像视觉质量

结论

网站图片可能会浮转或优化升到一定水平可使用图像格式、第三方库和API优化图像,但它们可能不象你需要的那样灵活。

云化提供综合图像管理解决方案,通过基于 URLAPI提供图像并变换图像可使用变换特征优化图像压缩

你可以注册免费云式账号并观察以URL解决方案优化图像的易易易性
