Hi Mark,
Thank you for the information.
The file was still corrupt after using "binfile:", but I found out something.
I hexdump'ed the corrupted file, and obviously the PNG file did not have any
headers. But files created with "export" command (which is not supported by
Revolution Engine 2.5) do have headers. So it looks like "put into url" command
does not add any headers to the file to be saved. And I wonder if what kind of
format an image is in when the image is "put into url."

Hi Takaaki,
The reason you are getting corrupted PNG's is probably because you are putting the image into a 'text' URL. You should do put myImage into URL "binfile:imagedir/myimage.png"
To clarify what's going on, if you put something into a 'file' URL, Revolution will assume what you are putting is text and output the appropriate end-of-line markers for the platform you are on. Using a 'binfile' URL will stop Revolution meddling in this way :o)
Some of you may have noticed the 'corrupt PNG messages' appearing on the
console in an earlier alpha/beta of Revolution 2.5 then this was the
cause... (Ahem) I kinda got caught out on this one when importing images
for revOnline...
Best wishes,
Mark.

I would like to export the data of an image object in either PNG or JPG
format in CGI.
But when I do this, I get a corrupted PNG file. I use Revolution Engine
2.5
(which doesn't seem to support "export image" command yet).
Maybe "put into url" cannot be used with image objects?
set the paintCompression to PNG import snapshot from rect "0,0,100,100" put last image into myImage put myImage into url "file:imagedir/myimage.png"
