1.1本规程描述了一种数据格式，用于将信息从缝制产品计算机辅助设计软件程序传输到产生物理输出的设备，通常以打印或绘制在纸上的图像的形式。 1.2本规程基于惠普图形语言HPGL/2的子集。7.2中列出了支持的语法和限制。X1.1中列出了不支持的语法。 1.3本惯例仅支持 X-Y 矢量数据和一组有限的附加函数。没有规定支持喷墨打印等应用中使用的位图/光栅数据。 1.4本规程支持单一单位制，图像以100%比例固定，纵横比为1:1。不支持缩放和自定义单位系统。 1.5本规程不支持曲线插值或定义。 所有曲线均由离散向量（冲程）表示，并取决于CAD软件的分辨率。 1.6本规程要求所有坐标均为绝对坐标，而非HPGL/2参考中定义的相对坐标。 1.7本规程仅支持从单个 X-Y 坐标为0,0的原点。 1.8本惯例仅支持固定宽度字体。不支持可变宽度字体。 1.9本规程旨在传输静态图像，无需编辑。 1.10本规程假设单色输出。它不支持隐含的输出颜色。 1.11本规程对绘图数据的宽度或长度没有限制。硬件施加的物理限制及其对输出的影响由硬件制造商负责。 1.12本规程不支持帧推进命令或插入多个原点或浮动坐标系的任何方法。 1.13本规程将绘图文件限制为包含由兼容标头和终止符取消标记的单个数据块。不允许在单个文件中包含多个数据块。 1.14本规程的预期应用仅限于生产服装、纺织品、室内装潢和其他使用软材料或半刚性材料的缝制产品行业中的输出装置类别。 1.15 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 该实践提供了一种通用格式，允许计算机设计系统生成输出设备可以独立于硬件制造商准确复制的数据。

1.1 This practice describes a data format for transferring information from a sewn product computer aided design software program to a device that produces physical output, typically in the form of a printed or drawn image on paper. 1.2 This practice is based on a subset of the Hewlett Packard Graphics Language HPGL/2. Supported syntax and limitations are listed in 7.2. Unsupported syntax is listed in X1.1. 1.3 This practice only supports X-Y vector data and a limited set of additional functions. No provision is made to support bitmap/raster data used in applications like inkjet printing. 1.4 This practice supports a single system of units, an image fixed at 100 % scale and 1:1 aspect ratio. Scaling and custom unit systems are not supported. 1.5 This practice does not support curve interpolation or definitions. All curves are represented by discrete vectors (stroked) and are dependent on the resolution of the CAD software. 1.6 This practice requires that all coordinates are absolute, not relative, as defined in the HPGL/2 reference. 1.7 This practice only supports positive coordinates that are measured from a single X-Y origin point with coordinates 0,0. 1.8 This practice only supports fixed width fonts. Variable width fonts are not supported. 1.9 This practice intends to transfer a static image with no provision for editing. 1.10 This practice assumes monochromatic output. It does not support implied output colors. 1.11 This practice imposes no limits on the width or length of the plot data. Physical limitations imposed by the hardware and their effects on the output are the responsibility of the hardware manufacturer. 1.12 This practice does not support frame advance commands or any methods that insert multiple origin points or floating coordinate systems. 1.13 This practice limits the plot file to contain a single block of data demarked by a compatible header and terminator. Multiple blocks of data in a single file are not allowed. 1.14 The intended application of this practice is limited to the class of output devices found in the sewn product industries that produce apparel, textiles, upholstery, and others that use soft or semi-rigid materials. 1.15 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This practice provides a common format that allows a computer design system to generate data that an output device can accurately reproduce independent of the hardware manufacturer.
