Export snapshot as jpeg has black border?[SOLVED]

[ClipArtGuy]

Hello! Is it possible to use a script like this:

Code: Select all

export snapshot from grp 1 to file (specialfolderpath("Desktop")&"/"MyTestIMG.jpg) as jpeg

WITHOUT the resulting file having a thin black border? If I export as PNG it makes this border transparent, which is OK, but I need my jpgs to not have a border also. I have "showborder" unchecked in property inspector of img 1.... The border appears in Ubuntu 64 bit and windows 7 using stable 7.0.6

Thanks!

HI ClipArtGuy,

1. welcome to the forum!

2. "export snapshot..." is usually working correctly and not adding anything to the resulting image!
Maybe your group has a tiny border? Sorry, just guessing...

Hello Klaus,


Thanks for the fast reply!

This recipe produces an image with a border:

Create a new stack

1 - Create a new large rectangle image - uncheck "showborder" and fill with white

2 - Put a small graphic oval over the middle of img 1 (with a height and width much smaller than the first image)

3 - Group them together and run this in message box:

Code: Select all

export snapshot from grp 1  to file (specialfolderpath("Desktop")&"/MyTestImage.jpg") as jpeg

Every time I do this I get exactly what I would expect,but with a black border around the whole saved image that is a few pixels thick.
Can you confirm or deny that this happens for you? I have tested on Ubuntu and Windows with identical results using LiveCode 7.0.6

Thanks again!

It seems that when the group is created, The group is 2 pixels larger on all sides than the image. I am not sure if this is a bug or a feature....

This script is working for me in a button now.

Code: Select all

on mouseUp
   set the height of grp 1 to (the width of grp 1 - 4)
   set the width of grp 1 to (the width of grp 1 - 4)
   set the loc of img 1 to the loc of grp 1
   export snapshot from grp 1  to file (specialfolderpath("Desktop")&"/MyTestImage.jpg") as jpeg
end mouseUp

By default new groups have their margins property set to 4. You can change that before creation in the templateGroup, or after creation on the new group.

Hi ClipArtGuy,

yes, true!

Looks like the MARGINS (Inspector for group -> Text formatting) of the group are causing this!
When set to 0 it works as advertised
