#inkfilepicker_image_url(url, options = {}) ⇒ Object

w - Resize the image to this width.

h - Resize the image to this height.

fit - Specifies how to resize the image. Possible values are:

clip: Resizes the image to fit within the specified parameters without
      distorting, cropping, or changing the aspect ratio
crop: Resizes the image to fit the specified parameters exactly by
      removing any parts of the image that don't fit within the boundaries
scales: Resizes the image to fit the specified parameters exactly by
        scaling the image to the desired size
Defaults to "clip".

align - Determines how the image is aligned when resizing and using the “fit” parameter. Check API for details.

cache - Specifies if the image should be cached or not.

crop - Crops the image to a specified rectangle. The input to this parameter

should be 4 numbers for 'x,y,width,height' - for example,
'crop=10,20,200,250' would select the 200x250 pixel rectangle starting
from 10 pixels from the left edge and 20 pixels from the top edge of the
image.

format - Specifies what format the image should be converted to, if any.

Possible values are "jpg" and "png". For "jpg" conversions, you
can additionally specify a quality parameter.

quality - For jpeg conversion, specifies the quality of the resultant image.

Quality should be an integer between 1 and 100

watermark - Adds the specified absolute url as a watermark on the image.

watersize - This size of the watermark, as a percentage of the base

image (not the original watermark).

waterposition - Where to put the watermark relative to the base image.

Possible values for vertical position are "top","middle",
"bottom" and "left","center","right", for horizontal
position. The two can be combined by separating vertical
and horizontal with a comma. The default behavior
is bottom,right
