This is a maintained fork of PySeq, with basic stereo support. This feature is not available via pip, only via a direct download from github. In addition to the usual features "eyes/views" can be specified via an envvar and then matching sequences get grouped together and displayed with %v/%V instead of the "eye/view" in the filename. (egg test.left.1001.exr and test.right.1001.exr) "eyes/views" can be more than two views such as (left2,left,middle,right,right2). There are additional convenience methods to iterate over items as this comes handy on the multiViewSequence class. - seq.getAllItems() Then a copy function will not work only for a normal sequence but for all its existing eyes/views. - img2pyseq is an attempt to construct a pyseq object without knowing its "boundaries", as uncompress does not satisfy that need
PySeq is a python module that finds groups of items that follow a naming convention containing a numerical sequence index (e.g. fileA.001.png, fileA.002.png, fileA.003.png...) and serializes them into a compressed sequence string representing the entire sequence (e.g. fileA.1-3.png). It should work regardless of where the numerical sequence index is embedded in the name. For examples, see basic usage below or http://rsgalloway.github.io/pyseq
Installation using setuputils:
% pip install pyseq
Using the "z1" file sequence example in the "tests" directory, we start by listing the directory
contents using ls
.
$ ls tests/files/z1* tests/files/z1_001_v1.1.png tests/files/z1_002_v1.3.png tests/files/z1_001_v1.2.png tests/files/z1_002_v1.4.png tests/files/z1_001_v1.3.png tests/files/z1_002_v2.1.png tests/files/z1_001_v1.4.png tests/files/z1_002_v2.2.png tests/files/z1_002_v1.1.png tests/files/z1_002_v2.3.png tests/files/z1_002_v1.2.png tests/files/z1_002_v2.4.png
Now we list the same directory contents using lss, which will find the sequences and display them in the default compressed format.
$ lss tests/files/z1* 4 z1_001_v1.%d.png [1-4] 4 z1_002_v1.%d.png [1-4] 4 z1_002_v2.%d.png [1-4]
... with a custom format:
$ lss tests/files/z1* -f "%h%r%t" z1_001_v1.1-4.png z1_002_v1.1-4.png z1_002_v2.1-4.png
... recursive:
$ lss -r tests tests ├── test_pyseq.py └── files ├── 012_vb_110_v001.1-10.png └── 012_vb_110_v002.1-10.png
Compression, or serialization, of lists of items
>>> s = Sequence(['file.0001.jpg', 'file.0002.jpg', 'file.0003.jpg']) >>> print s file.1-3.jpg >>> s.append('file.0006.jpg') >>> print(s.format("%h%p%t %R")) file.%04d.jpg [1-3, 6] >>> s.contains('file.0009.jpg') True >>> s.contains('file.0009.pic') False
Uncompression, or deserialization, of compressed sequences strings
>>> s = uncompress('012_vb_110_v002.1-150.dpx', format="%h%r%t") >>> len(s) 150 >>> seq = uncompress('./tests/012_vb_110_v001.%04d.png 1-10', format='%h%p%t %r') >>> print(seq.format('%04l %h%p%t %R')) 10 012_vb_110_v001.%04d.png [1-10]
