----------------------------------
Summary: TIFF reading extremely slow in version 1.0-SNAPSHOT
Key: IMAGING-356
URL: https://issues.apache.org/jira/browse/IMAGING-356
Project: Commons Imaging
Issue Type: Bug
Components: Format: TIFF
Affects Versions: 1.0
Reporter: Gary Lucas
I am using the latest code from github (1.0-SNAPSHOT downloaded from github of
June 2023) to read a 300 megabyte TIFF file. Version 1.0-alpha3 required 673
milliseconds to read that file. The new code requires upward of 15 minutes.
Clearly something got broken since the last release.
The TIFF file is a 10000x10000 pixel 4 byte image format organized in strips.
The bottleneck appears to occur in the TiffReader getTiffRawImageData method
which reads raw data from the file in preparation of creating a BufferedImage
object.
I suspect that there may be a general slowness of file access. In debugging,
even reading the initial metadata (22 TIFF tags) took a couple of seconds.
