The High Efficiency File Format (HEIF) is described in ISO/IEC 23008-12. LEADTOOLS supports reading and writing HEVC (H265) compressed single-image HEIC files.
The file constants associated with HEIC are:
|Constant||Read Support||Write Support||Description|
|Heic||24, 32, 48, 64 BPP||24 BPP||High Efficiency File Format with HEVC compression (HEIC).|
LEADTOOLS supports the following HEIC features:
8-bit and 10-bit components. Save 24-bit HEIC images using 8-bit color planes. Most HEIC files use three 8-bit color planes. Those files are loaded and saved as 24-bits per pixel. HEIC also supports 10-bits per pixel color planes. By default, HEIC files with 10-bit planes are loaded as 48-bit.
Alpha channel/transparency information. Use SetAlphaValuesCommand to manipulate the Alpha plane from fully translucent to fully opaque. If the HEIC file has an Alpha plane, LEADTOOLS will automatically load it. HEIC files with 8-bit color planes plus an Alpha plane use 32-bits per pixel of memory when loaded. HEIC files with 10-bit color planes plus an Alpha plane use 64-bits per pixel of memory when loaded. Alpha color component values provide full translucidity, semi-translucency or full opacity control as described in the table below:
Rotate, flip, and reverse transformations. Perform a lossless rotate, flip, or reverse transformation of an existing file using the Transform method.
