macUtils
ttLib.macUtils.py – Various Mac-specific stuff.
- fontTools.ttLib.macUtils.getSFNTResIndices(path)[source]
Determine whether a file has a ‘sfnt’ resource fork or not.
- fontTools.ttLib.macUtils.openTTFonts(path)[source]
Given a pathname, return a list of TTFont objects. In the case of a flat TTF/OTF file, the list will contain just one font object; but in the case of a Mac font suitcase it will contain as many font objects as there are sfnt resources in the file.
- class fontTools.ttLib.macUtils.SFNTResourceReader(path, res_name_or_index)[source]
Bases:
BytesIO
Simple read-only file wrapper for ‘sfnt’ resources.
- close()
Disable all I/O operations.
- closed
True if the file is closed.
- detach()
Disconnect this buffer from its underlying raw stream and return it.
After the raw stream has been detached, the buffer is in an unusable state.
- fileno()
Returns underlying file descriptor if one exists.
OSError is raised if the IO object does not use a file descriptor.
- flush()
Does nothing.
- getbuffer()
Get a read-write view over the contents of the BytesIO object.
- getvalue()
Retrieve the entire contents of the BytesIO object.
- isatty()
Always returns False.
BytesIO objects are not connected to a TTY-like device.
- read(size=-1, /)
Read at most size bytes, returned as a bytes object.
If the size argument is negative, read until EOF is reached. Return an empty bytes object at EOF.
- read1(size=-1, /)
Read at most size bytes, returned as a bytes object.
If the size argument is negative or omitted, read until EOF is reached. Return an empty bytes object at EOF.
- readable()
Returns True if the IO object can be read.
- readinto(buffer, /)
Read bytes into buffer.
Returns number of bytes read (0 for EOF), or None if the object is set not to block and has no data to read.
- readinto1(buffer, /)
- readline(size=-1, /)
Next line from the file, as a bytes object.
Retain newline. A non-negative size argument limits the maximum number of bytes to return (an incomplete line may be returned then). Return an empty bytes object at EOF.
- readlines(size=None, /)
List of bytes objects, each a line from the file.
Call readline() repeatedly and return a list of the lines so read. The optional size argument, if given, is an approximate bound on the total number of bytes in the lines returned.
- seek(pos, whence=0, /)
Change stream position.
- Seek to byte offset pos relative to position indicated by whence:
0 Start of stream (the default). pos should be >= 0; 1 Current position - pos may be negative; 2 End of stream - pos usually negative.
Returns the new absolute position.
- seekable()
Returns True if the IO object can be seeked.
- tell()
Current file position, an integer.
- truncate(size=None, /)
Truncate the file to at most size bytes.
Size defaults to the current file position, as returned by tell(). The current file position is unchanged. Returns the new size.
- writable()
Returns True if the IO object can be written.
- write(b, /)
Write bytes to file.
Return the number of bytes written.
- writelines(lines, /)
Write lines to the file.
Note that newlines are not added. lines can be any iterable object producing bytes-like objects. This is equivalent to calling write() for each element.
