Setting picturedata by reference

[cmclane]

I have not been able to set the picturedata of a draw rectangle graphic to a PNG image file by reference using what I think is a a correct path to the file. However, if I place the image file in the same folder as the SC project and use just the filename, not the full path, it works. What am I missing?

Supercard Help shows the example:

set the pictureData of bg grc “Holder” to reference file “Tree.pict” 

And says:

Only PICT files can be used with the reference keyword. Although other graphic formats (such as JPEG and GIF) can be used when embedding the source image directly in the object’s picture property, files in these formats cannot be used as referenced image files.

But in a recent post Mark said:

tt's probably also worth mentioning that . . . [setting the picturedata of a graphic] works MUCH better with pictureData set by reference (which nowadays supports any importable image format).

Can I set picturedata to a PNG file by reference? What is the best way to get the correct path? (I have tried the Get Info method and the drag the file to Terminal method with no success.) Do I need to set or reset file permissions somewhere?

That bit about only PICT files is obsolete.

Are you using an HFS path, and is this in SC or SE?

Here’s an update to the docs for this keyword:

Say what?

That’s a plain text file (for some unknown reason with no extension).

Did it show up differently at your end?

It comes up unformatted and un-wraped in BBEdit.

I'm just sayin'...

FWIW it ‘comes up’ as expected in TextEdit here.

One more reason (among many) I’m hatin’ the Google Groups UI…

1. I believe I am using the newer POSIX path format. I found this in a quick internet search:

Converting between formats

Assuming oldPath would be an alias or record of a finder item, use the following command to set a standard Applescript alias to a POSIX path:

 set thisPOSIXPath to (the POSIX path of oldPath)

 -- input: "Macintosh HD:Applications:Safari.app"

 -- output: "/Applications/Safari.app"

My path looks like the POSIX path, and that answers one of my questions because when I drop the file onto the Terminal the resulting path does NOT include "Macintosh HD:" which is apparently fine under the new format.

2. I am building the project (i.e. setting up the single card with a draw graphic rectangle object) in SE and then selecting Run which kicks me to SC. The script in the one button on the card that looks in the folder for the graphic loads it. The script in the other button on the card that looks to the desktop doesn't. (In fact there is not response, no error message, no nothing.)

It showed up here as a plain text file with no extension. But I can read it OK in TextEdit.

 For backwad compatibility SC still uses (and expects) HFS paths.

If you have a POSIX path, you can use posixToHFS() to convert it to HFS format.

That did it. Thanks Mark!
