关於 TGA (Tagged Graphics) 文件
TGA 是由美国 Truevision 公司为其显示卡开发的一种图像文件格式,已被国际上的图形、图像工业所接受。现在已成为数字化图像,以及运用光线跟踪算法所产生的高质量图像的常用格式。TGA 文件的扩展名为 .tga。TGA 的结构比较简单,属于一种图形、图像数据的通用格式,目前大部分文件为24位或32位真彩色,在多媒体领域有着很大影响。由于 Truevision 公司推出 TGA 的目的是为了采集、输出电视图像,所以 TGA 文件总是按行存储、按行进行压缩的,这使得它同时也成为计算机生成图像向电视转换的一种首选格式。
TGA 图像格式最大的特点是可以做出不规则形状的图形、图像文件,一般图形、图像文件都为四方形,若需要有圆形、菱形甚至是缕空的图像文件时,TGA 可就派上用场了。TGA 格式支持压缩,使用不失真的压缩算法。
Dosch Viz-Images: People - Shopping & Travel is an effective way for adding people in various shopping or travel situations to your visualization. From shopping basket to standing in line ... from the newspaper-reading wait with suitcase to the impatient "watch-checking". Many such scenes are included here.
The clip-maPS are perfect "cut-outs", i.e. blend into their respective background and surrounding beautifully and naturally - they become part of the overall scene and don't look artificial or super-imposed. The high-resolution images have a size of around 1000 x 2500 pixel per person. |
