Format notes
- Lossless compression for JPEG-2000 (JP2): ABIC uses the OpenJPEG library (see this page) for compression and decompression of JPEG-2000 images. The other well-known open source JPEG-2000 codec, jasper, is not able to losslessly compress and decompress 16-bit images. Please keep that in mind when using images created with ABIC with other software.
- TIFF compressions: ABIC allows to generate LZMA compressed TIFFs. This format is marked "experimental" by the TIFF authors. Most other software will not be able to read such files. Also JPG-compressed TIFFs are not supported by most other software. ABIC in turn does not support 12-bit JPEGs embedded in TIFFs.
- WebP files can be compressed either losslessly or lossy. The lossy compression can be defined with a quality value, similar to JPEG. But for WebP there are two more compression schemes: Quality-based (PSNR) and Ratio (resulting file size). Both schemes in fact only iteratively estimate the quality value to reach the target value of PSNR or ratio. To reach the target value more accurately, increase the "passes" (iterations) value.
- The support for vector graphics formats MVG and SVG is limited: They can only be read, not written; drawing text depends on the availability of fonts; complex SVG files are rendered incorrectly.
The following table shows the capabilities of the 5 main image file formats supported by ABIC:
| Lossy | Lossless | 16-bit capable | |
|---|---|---|---|
| JPG | X | ||
| JP2 (JPEG-2000) | X | X | X |
| PNG | X | X | |
| TIFF | X | X | X |
| WebP | X | X |
Supported formats
The following table shows all image file formats that ABIC can read and/or write. Some of the formats in this list are duplicates, some are obsolete.
The formats EMF and WMFWIN32 are only supported on Windows.
The column "R" indicates whether ABIC can read this file format, the column W indicates whether ABIC can write this format.
