Lua Player .20 released!
Lua Player .20 has been released!
new stuff:
v0.20
==========
- updated for gcc 4.1 and Lua 5.1. Some things you need to change for 5.1:
- change table iteration code:
"for i, value in someTable do" to
"for i, value in ipairs(someTable) do"
(but use "pairs" for tables like "t={foo=bar, foobar=99}"
and "ipairs" for tables like "t={foo, bar}")
- it's pure Lua 5.1: no binary operators and double as number type
(e.g. now you can use one number for storing IP addresses)
- Sound.load doesn't crash any more on invalid filenames
- fixed problems with daylight saving time
- Font:getTextSize fixed. Test case:
proportional = Font.createProportional()
proportional:setPixelSize s(0,8)
test = proportional:getTextSize( 'some text')
assert(test.width == 39)
assert(test.height == 6)
- blit operation from screen to image works now, e.g.:
screen rint(10, 10, "hello", Color.new(255,255,255))
image = Image.createEmpty(480, 272)
image:blit(0, 0, screen, 480, 272, 480, 272, true)
and now you have an "image" with the text "hello"
- TTF font plotting to images now sets the alpha value to opaque, so
you can write e.g. something like this for buffering texts in images:
image = Image.createEmpty(400, 200)
proportional = Font.createProportional()
proportional:setPixelSize s(0, 16)
image:fontPrint(proportio nal, 0, 20, 'Hello', Color.new(0, 255, 0))
screen:blit(0, 0, image)
screen:blit(3, 3, image)
- new function Image.loadFromMemory for loading images from memory:
jpegFile = io.open("test.jpg", "rb")
data = jpegFile:read("*a")
jpegFile:close()
image = Image.loadFromMemory(data )
PNG and JPEG is supported and autodetected
- image-to-image blitting now uses alpha full blending [Callum Bethune]
- System.rename(oldName, newName) for renaming files and directories
