Resize
Resize layer (resize
) resizes data (image + annotation) to the certain size.
{ "action": "resize", "src": ["$data1"], "dst": "$data2", "settings": { "width": 800, "height": 600, "aspect_ratio": { "keep": true } } }
-
"aspect_ratio": "keep" — flag (
true
orfalse
). Iftrue
result should save original proportions. -
width
— width in pixels or-1
. If value is equal to-1
and"keep": true
then for specificheight
width
will be automatically computed to keep aspect ratio. The case when value is equal to-1
and"keep": false
is not allowed. -
height
— height in pixels or-1
. If value is equal to-1
and"keep": true
then for specificwidth
height
will be automatically computed to keep aspect ratio. The case when value is equal to-1
and"keep": false
is not allowed.
Use case: resize to specific width¶
{ "action": "resize", "src": ["$data1"], "dst": "$data2", "settings": { "width": 800, "height": -1, "aspect_ratio": { "keep": true } } }
Result will be the following:
Height will be automatically computed and it is 600 px in this example.
Use case: resize to specific height¶
{ "action": "resize", "src": ["$data1"], "dst": "$data2", "settings": { "width": 400, "height": 300, "aspect_ratio": { "keep": true } } }
Result will be the following:
Width will be automatically computed and it is 400 px in this example.
Use case: resize to specific width and height without keeping aspect ratio¶
{ "action": "resize", "src": ["$data1"], "dst": "$data2", "settings": { "width": 2000, "height": 500, "aspect_ratio": { "keep": false } } }
Result will be the following:
Use case: resize to specific width and height with keeping aspect ratio¶
{ "action": "resize", "src": ["$data1"], "dst": "$data2", "settings": { "width": 2000, "height": 500, "aspect_ratio": { "keep": true } } }
Result will be the following:
As we can see, additional black padding is added to save both certain image size (width=2000 and height=500) and original proportions.
