Namespaces | |
| namespace | ImageUtil |
Functions | |
| bool | ImageUtil::loadFile (const std::string &file, char *&buf, size_t &size) |
| loads a file into memory, returns true if successful | |
| void | ImageUtil::releaseFile (char *buf, size_t size) |
| releases memory from a previous call to loadFile, triggering munmap() or 'delete' as appropriate | |
| bool | ImageUtil::decodeJPEG (char *inbuf, size_t inbufSize, size_t &width, size_t &height, size_t &channels, char *&outbuf, size_t &outbufSize, const std::string &filename="") |
| decodes a JPEG image already in memory, returns true if successful | |
| bool | ImageUtil::decodePNG (char *inbuf, size_t inbufSize, size_t &width, size_t &height, size_t &channels, char *&outbuf, size_t &outbufSize) |
| decodes a PNG image already in memory, returns true if successful | |
| bool | ImageUtil::decodeImage (char *inbuf, size_t inbufSize, size_t &width, size_t &height, size_t &channels, char *&outbuf, size_t &outbufSize) |
| decodes an image already in memory -- if it looks like a PNG decodePNG() will be called, otherwise decodeJPEG(); returns true if successful | |
| bool | ImageUtil::loadJPEG (const std::string &file, size_t &width, size_t &height, size_t &channels, char *&outbuf, size_t &outbufSize) |
| decodes a JPEG from disk, returns true if successful | |
| bool | ImageUtil::loadPNG (const std::string &file, size_t &width, size_t &height, size_t &channels, char *&outbuf, size_t &outbufSize) |
| decodes a PNG from disk, returns true if successful | |
| bool | ImageUtil::loadImage (const std::string &file, size_t &width, size_t &height, size_t &channels, char *&outbuf, size_t &outbufSize) |
| decodes an image from file on disk -- if it looks like a PNG decodePNG() will be called, otherwise decodeJPEG(); returns true if successful | |
| size_t | ImageUtil::encodeJPEG (char *inbuf, size_t inbufSize, size_t width, size_t height, size_t inbufChannels, char *&outbuf, size_t &outbufSize, size_t outbufChannels, int quality) |
| encodes a JPEG from a pixel buffer into another memory buffer, returns number of bytes used, 0 if error | |
| size_t | ImageUtil::encodeJPEG (char *inbuf, size_t inbufSize, size_t width, size_t height, size_t inbufChannels, char *&outbuf, size_t &outbufSize, size_t outbufChannels, int quality, jpeg_compress_struct &cinfo) |
| encodes a JPEG from a pixel buffer into another memory buffer, returns number of bytes used, 0 if error | |
| size_t | ImageUtil::encodeJPEG (char *inbuf, size_t inbufSize, size_t width, size_t height, size_t inbufChannels, char *&outbuf, size_t &outbufSize, size_t outbufChannels, int quality, unsigned int yskip, unsigned int uvskip, jpeg_compress_struct &cinfo) |
| encodes a JPEG from a pixel buffer into another memory buffer, returns number of bytes used, 0 if error | |
| size_t | ImageUtil::encodePNG (char *inbuf, size_t inbufSize, size_t width, size_t height, size_t inbufChannels, char *&outbuf, size_t &outbufSize, size_t outbufChannels) |
| encodes a JPEG from a pixel buffer into another memory buffer, returns number of bytes used, 0 if error | |
