Originated in
Troi URL Plug-in 2.0
Compatibility
FileMaker Pro 16 to 19
Considerations
Some web pages have images which have the wrong extension, for example abc.jpg, which is then actually a GIF. This function makes it possible to detect this.
v7.0 added the switch “-ImageFileName”
Example
TURL_GetLastProperties ( "-ImageType" )will for example return “JPEG”.
Example 2
Set Field [ containerField ; TURL_Get ( "-unused" ; "https://www.troi.com/ima/sm_peter.jpg" ) ]
Set Field [ imageType ; TURL_GetLastProperties ( "-ImageType" ) ]
Set Field [ imageWidth ; TURL_GetLastProperties ( "-ImageWidth" ) ]
Set Field [ imageHeight ; TURL_GetLastProperties ( "-ImageHeight" ) ]This will get an image and put it into a containerField and fill the other fields with JPEG, 48 and 48 respectively.
