Image Zero Disk Usage Slicer
Splits an image into 4 separate images of the same size, each dimension of original image is halved.
Runs on port :9090 by default. Set env variable PORT to change it.
Send POST to :9090 with the following JSON body:
{
"image_url": "<url to image>"
}Optionally you can specify ?scale=<size> (size in px) to downscale the image.
Aspect ratio will be preserved.
0 means no scaling.
You'll receive Response Stream. Each chunk represents a single image, yet you should not rely on chunks too much. In case of small images (downscaled) multiple chunks might be sent quickly. You need to parse the total byte sequence and find the beginning of each image.
For PNG (the only supported format for now) you should search for (0x87 PNG) header:
HEX: [0x89, 0x50, 0x4E, 0x47] or
Decimal: [137, 80, 78, 71]
Feel free to use CLI client for testing and example purposes.
