Scaling Syntax

The basic format for the string is (terms in square brackets are optional):


where SCALING_INFORMATION has the format:

[fit] WIDTH [x HEIGHT]

with WIDTH and HEIGHT defined as whole numbers in terms of pixels. For example, "210" means "210px", but it is also possible to type "210px".


JPG/PNG/GIF/TIFF [low/med/hi] [prog(ressive)] [inter(laced)]

which allows you to set the file type, quality of the image and various further options (progressive for .jpg files and interlaced for .png files).



Scales an image to 80% of the original image, keeping the same file format as the input image.

500px x 50px

Scales the image to be 500px in width by 50px in height. The format is kept the same as the original.

x200 as gif

Scales the image to be 200px in height, maintaining the width so as to scale the image. Saves the result as a GIF file.

fit 640x480 as jpg high progressive

Creates a JPEG image that will fit within a 640x480 rectangle and is of high quality with progressive enabled.

50% as interlaced png

Creates a PNG with dimensions half of the original.

Trigger Events

Event Triggers can be run when images are resized or reformatted by this plug- in. For both actions, the "Event Trigger Object" will refer to the new image file(s).
