jbig

1. JBIG uses a form of arithmetic coding patented by IBM known as the Q-coder.

jbig使用了一种形式的算术编码专利，由ibm称为问答式编码器。

2. JBIG was designed for compression of binary images, particularly for faxes , but can also be used on other images.

jbig是专为压缩的二进制图像，尤其是对传真文件，但也可用于其他的图像。

3. JBIG also supports progressive transmission with small (around 5%) overheads.

jbig还支持渐进传输与小（约百分之五）的间接费用。

4. Moreover, the complexity of both the time and space to compress binary images is lower than that got by using JBIG standard.

同时该算法的时间复杂度和空间复杂度均低于采用JBIG标准来压缩二值图像。

5. In most situations JBIG offers between a 20% and 50% increase in compression efficiency over the Fax Group 4 standard, and in some situations, it offers a 30-fold improvement.

在大多数情况下jbig优惠之间的20%和50%的增长，压缩效率比传真第4组的水准，并在某些情况下，它提供了30倍的改善。

6. Now that the newer bi-level image compression standard JBIG2 has been released, JBIG is also known as JBIG1 .

现在较新的双水平图像压缩标准应用于jbig2已被释放，jbig又被称为jbig1。

7. Support for tiff, zlib, raw, png, mng, jpeg, jasper, jbig a variety of formats, such as image compression.

详细说明： C++的处理图像类。支持tiff、zlib、raw、png、mng、jpeg、jasper、jbig等各种格式压缩图片。
