Example Synatax
Width Specific
iipimage-server-url?FIF=/Full/Pyramid/Path&SDS=0,90&CNT=1.0&WID=128&QLT=75&CVT=jpeg
Height Specific
- iipimage-server-url?FIF=/Full/Pyramid/Path&SDS=0,90&CNT=1.0&HEI=128&QLT=75&CVT=jpeg
Minimal Details
- iipimage-server-url?FIF=/Full/Pyramid/Path&WID=128&CVT=jpeg
- iipimage-server-url?FIF=/Full/Pyramid/Path&HEI=128&CVT=jpeg
Variables
The order of the GET variables included in the URL is important, feel free to try and experiment :-)
- FIF: Absolute file path for the pyramidal image.
- SDS: Sorry not found a link for this one yet. Optional value.
- CNT: Contrast adjustment. Try decreasing or increasing this values by multiples of 0.1 to see the effect. Optional value.
- WID or HEI: Defined pixel dimension of the generate image, at the time of writing the specific dimension of the resultant images will be 1 below the defined number. I assume that this is a result of rounding issues or it may be related to the fact that many numerical systems within programming begin with 0 rather than 1. The maximum possible pixel dimension (width or height) irrespective of which variable is defined can be limited using the MAX_CVT server variable, see website for more details.
- QLT: Jpeg compression quality. A default value can be set for this using the JPEG_QUALITY server variable, see website for more details. Optional value.
- CVT: This lets the server know that you require a single full version of the image.
Notes
- Please note in the examples given below the &.jpg suffix at the end of some of the address within the MediaWiki syntax is not needed by IIPImage, it is just required to ensure that MediaWiki treats it like a normal external image.
