It was supposed to be called Paintbrush, but Google told me that a MacOS software is already called "Paintbrush". Do you have any suggestions ?Maybe a mix between MS Paint and Nspire that gives nSpaint ?
Thanks to Inspired Lua for this page !I'm glad you liked it :)
Draw and erase tools !
Maybe a mix between MS Paint and Nspire that gives nSpaint ?I like your idea ! It's now called nSpaint
Did you update the 1st post tns attachment?Oh, I forgot that ! Sorry. The latest version is attached to this post.
Unless I have a cache problem, it is byte to byte identic with the one I downloaded 2 days ago...
I just have a small suggestion that could possibly be added later. There's a boolean that returns true if the calc is color, but if it's greyscale it returns false, you could make only one slider for the grey level in the color selector.Even if we can't see the color, I think that it's useful to create RGB pictures on greyscale calcs (because we can send pictures/lua scripts to CX calcs)
Updated code please?
Oh, I forgot that ! Sorry. The latest version is attached to this post.
I meant the Lua source code :DOnce again, nice job!
Updated code please?
Answer :Oh, I forgot that ! Sorry. The latest version is attached to this post.
=)
I meant the Lua source code :D
Did you try Luna (http://www.ticalc.org/archives/files/fileinfo/441/44113.html)?Just saw it and was amazed.
--basic
{"image1", "image2", "image3" .... "image1337"}-->listpic
--lua
img_d = var.recall("listpic")
img = {}
for i, #img_d do
img[i] = image.new(img_d[i])
end
"\123" == string.char(123)
\ codes are just ways to represent ascii chars :)I like the new features. I didn't try this yet but I should really do so, soon. I haven't read the thread yet but I am curious how the sprite saving/exporting (if any exporting) works? Is it possible to create sprites for use in other tns files? I don't recall the Nspire having any form of external file like on the 83+.
I see, but how do we retrieve it? Is there a function in Lua that does that or do you access memory directly?There are clipboard setter and getters, yes.
