Re: export imagedata into a file ?

[Jacques Hausser via use-livecode]

Sorry, I didn’t read carefully.
But I think that the imageData needs a kind of “frame” to become an image. So 
the simplest way to do it is to populate, for instance, an hidden image with 
the imageData and then export it.

Re: export imagedata into a file ?

[Colin Holgate via use-livecode]

I was failing to even get the image in! But, the thing I would have tried if 
that had worked would be to set the paintCompression of the image to “jpeg".

Re: export imagedata into a file ?

[Jacques Hausser via use-livecode]

Hi jbv

I’m using not the imageData, but the image itself

Export image  “mage_testI” to URL”binfile:/test.jpg” as JPEG

It works

Hi list,
I have a script that starts as follows :

  put URL "binfile:/myFile.jpg" into tImageData
  put tImageData into image "Image_test"
  put the imagedata of image "Image_test" into tImageData
  -- tImageData processing

After tImageData is processed, I would like to export
its content directly into a file.
I tried :
  put tImageData into URL "binfile:/test.jpg"
but the file is considered corrupted and can't be opened.

I also tried :
  put tImageData into URL "binfile:/test.jpg" as JPEG
but it returns an error.

I know I can set the imagedata of an image to the content
of tImageData, and then use "export snapshot", but for some
reasons too long to explain, I would like to follow a different
path.
So, How can I export the binary content of tImageData to
a jpeg or png file that can be opened like any similar
file ?

Thanks in advance,
jbv

export imagedata into a file ?
