关于TIFF和PNG格式的技术细节
Tagged Image File Format
Also known as TIF. Requires tiff-v3.6.1.tar.gz or later. Use -define to specify the rows per strip (e.g. -define tiff:rows-per-strip=8). To define the tile geometry, use for example, -define tiff:tile-geometry=128x128. To specify a signed format, use -define quantum:format=signed. To specify a single-precision floating-point format, use -define quantum:format=floating-point. Set the depth to 64 for a double-precision floating-point format. Use -define quantum:polarity=min-is-black or -define quantum:polarity=min-is-white toggle the photometric interpretation for a bilevel image. Specify the extra samples as associated or unassociated alpha with, for example, -define tiff:alpha=unassociated. Set the fill order with -define tiff:fill-order=msb|lsb. Set the TIFF endianness with -define tiff:endian=msb|lsb. Use -define tiff:exif-properties=false to skip reading the EXIF properties. You can set a number of TIFF software attributes including document name, host computer, artist, timestamp, make, model, software, and copyright. For example, -set tiff:software "My Company". If you want to ignore certain TIFF tags, use this option: -define tiff:ignore-tags=comma-separated-list-of-tag-IDs. Since version 6.9.1-4 there is support for reading photoshop layers in TIFF files, this can be disabled with -define tiff:ignore-layers=true. To preserve compression of the source image, use: -define tiff:preserve-compression=true.
Portable Network Graphics
Requires libpng-1.0.11 or later, libpng-1.2.5 or later recommended. The PNG specification does not support pixels-per-inch units, only pixels-per-centimeter. To avoid reading a particular associated image profile, use -define profile:skip=name (e.g. profile:skip=ICC).
