apart from saving graphic from rendered texture, everything was possible even before, as with UrlLoader, you can download image to |D| folder and create a bitmap from texture that is saved there

thanks, can UrlLoader be also used to 'load' an image from the sd card? usually such files that the user wants to use are locally on the machine.

ar2rsawseen · October 2013

unfortunately no, UrlLoader is only meant for networking

keszegh · October 2013

so then the exact case what i asked for - even the import/load part - is not possible after all, it seems. could it be made possible? of course i can write my own 'file explorer' class, with the appropriate gideros file functions this is already possible, but at the end i need to import the image into |D|, which is apparently not yet possible.
thanks

@keszegh, I think lfs plugin (bundled with Gideros) might be what you are looking for, but not 100% sure:
http://keplerproject.github.io/luafilesystem/manual.html#reference

for example listing files in a directory:

require"lfs"
 
function listdir (path)
	for file in lfs.dir(path) do
		if file ~= "." and file ~= ".." then
			local f = path..'/'..file
			print (f)
		end
	end
end
 
listdir (".")

i think i was not clear, i meant that listing part IS possible (indeed with lfs, i did not remember it from my head). but i'm not sure if its possible to copy a file from some folder on the sd to |D| so that it can be used as a bitmap. your previous comment implied that it is not yet possible (or is it with file.read/write?). thus i asked for this feature, as it would be quite handy and should be easy to implement in gideros.

ah I'm so sorry, I've catched a cold and probably not thinking straight.

Well I know something like this works on PC:

local function copy(src, dst)
	local srcf = io.open(src, "rb")
	local dstf = io.open(dst, "wb")
	local size = 2^13      -- good buffer size (8K)
	while true do
		local block = srcf:read(size)
		if not block then break end
		dstf:write(block)
	end
	srcf:close()
	dstf:close()
end
copy("D://test.txt", "|D|test.txt")

but on mobile phones there might be some OS restrictions and some sections can be off the limit, although sdcard usually seems to be accessible

keszegh · October 2013

thanks for your help, that sounds good, it's still some time till i will have an opportunityi to use it in my app (probably after gideros 2.0 so i can also change the imported image), i will complain at that time if it's not working.

keszegh · October 2013

@ar2rsawseen, actually i've found that earlier i've asked and answered the same question, no comment: www.giderosmobile.com/forum/discussion/2072/how-to-load-images-from-a-folder-on-sdcard

Happens to the best of us

Any update on version 2? From what I've seen written on the forum, this is probably holding off a lot of other goodies (desktop,etc).

tkhnoman · December 2013

Hmm... Just wondering.
Would Sprite and MovieClip have setEffect?

ar2rsawseen · December 2013

@gianmichele sorry somehow I missed your post.
Currently some bug fixes etc are getting in the way of developing 2.0 version, but it has progress, as for example LuaJIT which will soon be released

@tkhnoman I think that eventually all texture holders (and probably also Sprite inherited objects) would get setEffect

I had forgotten to check if Shader support was done and just remembers as I was doing some OpenGL 3.0 work and I thought "I wonder if Gideros ever finished getting OpenGL 2.0 running?". I'm guessing not as no one seems to be talking about it hear. I am confused as now that 3.0 is out and even some mobile devices like Tegra 5 soon to be on the horizon have full GL 4.3 support how you are going to keep up...or should I say get caught up. There are some great performance boosts with 3.0 and you still don't have 2.0? I liked Gideros when I worked with it but found it just too limiting even with basic features like clipping.

ar2rsawseen · January 2014

@BlueByLiquid don't worry, we will get there

But no one would actually justify having 3.0 support, while it is not supported by majority. Unless it is completely backwards compatible.

Hmm, then maybe we should skip 2.0 and move to 3.0
