Function to measure pixels

[bonngo]

Does anyone know of a function or calculation that measures the pixels of an image?

Thanks.

If it's inserted [x] As reference only, then the dimensions are available from the container.

GetAsText ( container field ) returns something like:

size:640,480

image:Pictures/Brooklin.jpg

imagemac:/Macintosh HD/Users/fej/Documents/FileMaker/My_FM/CONTAINER/ContainerPictures/Pictures/Brooklin.jpg

So you can parse it out of the 1st line, using GetValue().

If the image has been "embedded", ie., not as a reference, then you can't get the dimensions from FileMaker anymore (which is strange, but true). You just get the name.

You would have to Export Field Contents to copy it out as a file again. Then you could use AppleScript to get the dimensions.

Length(containerField) will give you the size in pixels.

Not exactly: Length() returns the size of the object (i.e. the embedded file) in bytes, which is not the same as pixels, esp. with compressed images.

Correct as usual Comment.
