Lua Player version 0.20

[Shine]

On http://www.luaplayer.org you can get the new version 0.20. It is updated to Lua 5.1, there are some bugfixes and a new function for loading images from memory. I'll try to add pspgl the next week.

The changelog:

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:

  Code: Select all

      proportional = Font.createProportional()
      proportional:setPixelSizes(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.:

  Code: Select all

       screen:print(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:

  Code: Select all

       image = Image.createEmpty(400, 200)
       proportional = Font.createProportional()
       proportional:setPixelSizes(0, 16)
       image:fontPrint(proportional, 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:

  Code: Select all

       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
