Image Compression (original) (raw)
LEADTOOLS has been the leading supplier of standard-based and superior proprietary alternative image compression and decompression SDK for many commercial applications. It brings over decades of optimized code from compressing bi-tonal images used in document management to extended grayscale images widely used in life science industries.
The wide range of compression technology offered by LEAD can greatly improve performance of any imaging application or system. Various lossless compressions can be used to compress an image without compromising integrity of the image data; whereas with a little loss of image data, an application or system can achieve tremendous performance gains by greatly reducing the image size, image loading and saving time, and transmission time over the network.
LEADTOOLS offers optimized image compression with the following benefits to an application:
- Decreased storage requirement
- Improved transmission speed within a system, over networks, and over phone lines
- Improved load/save time (i.e., relatively smaller amount of time to perform data read/write to disk)
The following compression formats are supported by LEADTOOLS software:
