A mark file can specify abstract color using various color systems, or color spaces that fall into three broad categories:

  • Device color spaces (DeviceGray, DeviceRGB, DeviceCMYK) directly specify colors or shades of gray that an output device produces.
  • CIE-based color spaces (CalGray, CalRGB, ICCBased) are based on an international standard for color specification, and specify colors that are independent of the characteristics of any particular output device.
  • Special color spaces add features or properties to an underlying color space, allowing for patterns, color mapping, separations, and high-fidelity, multi-tone color. The corresponding color space categories are Pattern, Indexed, Separation, and DeviceN. Indexed color spaces must specify a base color space that may be a CIE-based, Device, Separation, or DeviceN space. Separation and DeviceN color spaces must specify an alternate color space.

Pandora lets you add (but not edit) the attributes of marks constructed with specific color space information or graphic objects.

标记文件可以使用各种颜色系统,或者使用归入以下三大类颜色空间,来指定抽象颜色:

  • 设备颜色空间 (DeviceGray、DeviceRGB、DeviceCMYK)直接指定输出设备产生的颜色或灰影。
  • 基于 CIE 的颜色空间 (CalGray、CalRGB、ICCBased)基于一种国际标准颜色规范,并独立于任何特定的输出设备的特征来指定颜色。
  • 特殊颜色空间 向基础颜色空间添加特性或属性,添加时会考虑模式、颜色映射、分色、高逼真度和多色调色。 相应的颜色空间类别是 Pattern、Indexed、Separation 和 DeviceN。 Indexed 颜色空间必须指定一个基础颜色空间,该基础颜色空间可以是基于 CIE 的颜色空间、Device、Separation 或 DeviceN 颜色空间。 Separation 和 DeviceN 颜色空间必须指定备用颜色空间。

对于用特定颜色空间信息或图形对象构建的标记,Pandora 允许您添加(但不能编辑)其属性。
