How do you copy a binary file?

ndoss

I want to copy a binary file from the resource area to the document area ("|D|"). I thought I'd be able to do it like so:

local function copyFile(destination, source) local ok = true   local infile = io.open(source, "rb") ok = ok and (infile ~= nil)   local outfile = io.open(destination, "wb") ok = ok and (infile ~= nil)   if ok then local indata = infile:read("*a") ok = ok and (indata ~= nil)   if ok then ok = ok and outfile:write(indata) end end   if infile then io.close(infile) end if outfile then io.close(outfile) end   return ok end   -- Code to see if it worked local copyWorked = copyFile("|D|out.png", "in.png") if copyWorked then stage:addChild(Bitmap.new(Texture.new("|D|out.png"))) end

When I run this, I get the following error:

|D|out.png: File is not a PNG file.

Any ideas about what I might be doing wrong? A better way to do this?

I'm running this on the desktop player under wine/linux. If I open the |D|out.png file with gimp, it opens correctly.

Hi,

Your code seems perfectly ok. When I tested it on Mac, Windows, Linux (wine) and Android, it worked. But my image is Examples/Graphics/Bird Animation/gfx/bird_white_01.png

Also in my test, "diff in.png |D|out.png" shows that these two files are same.

Can you attach your in.png?

Argh, I apparently chose a png that wouldn't load into Gideros at all ... it wasn't my copy that messed it up.

I've attached my bad png.

Looks like a jpeg file
