Command line usage¶
General¶
When installing flask-resize with pip you’ll get a command installed along it called flask-resize. See below for the sub commands and what they’re used
for.
Usage¶
usage: flask-resize [-h] {generate,list,sync,clear} ...
Sub-commands:¶
generate¶
Generate images passed in through stdin. Return URL for resulting image
Useful to generate images outside of the regular request/response cycle of a web app = happier visitors who don’t have to wait until image processing by Flask-Resize completes. Care has to be taken so that the exact same arguments are passed in as what is specified in code/templates - the smallest difference in passed in options will cause flask resize to generate a new image.
Use GNU Parallel or similar tool to parallelize the generation
flask-resize generate [-h] [-d DIMENSIONS] [-f FORMAT] [-q QUALITY] [-F]
[-b BGCOLOR] [-u] [--progressive] [--placeholder]
filename
Positional Arguments¶
| filename | None |
Named Arguments¶
| -d, --dimensions | |
| None | |
| -f, --format | None |
| -q, --quality | 80 Default: 80 |
| -F, --fill | False Default: False |
| -b, --bgcolor | None |
| -u, --upscale | True Default: True |
| --progressive | True Default: True |
| --placeholder | False Default: False |
sync¶
Undocumented
flask-resize sync [-h] {cache} ...
Sub-commands:¶
Syncs paths stored in the cache backend with what’s in the storage backend
Useful when the storage backend destination is shared between multiple environments. One use case is when one has synced generated imagery from production into one’s development environment (for example with aws s3 sync –delete s3://prod-bucket s3://my-dev-bucket). The cache can then be synced with what’s been added/removed from the bucket my-dev-bucket.
flask-resize sync cache [-h]
