Client for Ethumbd server.
|

|
|

|
This client is the recommended way to generate thumbnails with
|
||||||
|
Ethumb. All you have to do is create a client instance, wait it to
|
||||||
|
be connected to server, configure thumbnail parameters and then
|
||||||
|
start feed it with file_set(), exists() generate(). Basic steps are:
|
||||||
|
|
||||||
|
- instantiate Client, wait for func to be called with success.
|
||||||
|
- set various parameters, like format and size.
|
||||||
|
- loop on original files:
|
||||||
|
|
||||||
|
- ``c.file_set(file)``
|
||||||
|
- ``if not c.exists(): c.generate(generated_cb)``
|
||||||
|
|
||||||
|
When the last reference to client is released, server is
|
||||||
|
automatically disconnected. Since callback may contain references
|
||||||
|
to server itself, it is recommended explicit call to
|
||||||
|
:py:func:`disconnect` function.

image is 1000x500, resulting thumbnail is 256x128.
|
||||||
|
|
||||||
|
If aspect is ignored (ETHUMB_THUMB_IGNORE_ASPECT), then image
|
||||||
|
will be distorted to match required thumbnail size. Example:
|

|
size is 256x256, image is 1000x500, resulting thumbnail is
|

|
256x256.
|
||||||

|
If crop is required (ETHUMB_THUMB_CROP), then image will be
|
||||||
|
cropped so the smallest dimension is not bigger than its
|
||||||
|
specified size (see :py:func:`size_get`) and the other dimension
|
||||||
|
will overflow, not being visible in the final image. How it
|
||||||
|
will overflow is speficied by :py:func:`crop_set`
|
||||||
|
alignment. Example: size is 256x256, image is 1000x500, crop
|
||||||
|
alignment is 0.5, 0.5, resulting thumbnail is 256x256 with 250
|
||||||
|
pixels from left and 250 pixels from right being lost, that is
|
||||||
|
just the 500x500 central pixels of image will be considered
|
||||||
|
for scaling.
