| sensor_msgs::CompressedImage IZ::compressImage | ( | const sensor_msgs::Image & | image | ) |
Uses the ImageZero algorithm to compress a raw Image into a CompressedImage. The raw image must have 3 channels and either 8 or 16 bits per channel.
| [in] | image | An uncompressed 24-bit color image. |
Definition at line 55 of file ros_support.cpp.
| sensor_msgs::Image IZ::decompressImage | ( | const sensor_msgs::CompressedImageConstPtr & | compressed | ) |
Decompresses an image that had previous been compressed using ImageZero and returns a raw image.
| [in] | compressed | An image that was compressed with ImageZero. |
