Bart van Strien c02ba91ef4 Fix segfault loading images from compressed data without an explicit sRGB flag 2015-08-01 14:22:36 +02:00
Alex Szpakowski 66942d5f31 Added the ability to use custom mipmaps in Images, via love.graphics.newImage(filename, {mipmap1, mipmap2, ...}). Resolves issue #1064.
All mipmap levels must be present if custom mipmaps are used (and their sizes must be half the size of the previous mipmap level, rounded down.)

Image:getData now returns all custom mipmaps in an Image.

Alex Szpakowski ed3f419747 Prevent redundant calls to glEnable/DisableVertexAttribArray. This should hopefully fix a performance regression compared to 0.9.2 as well. 2015-06-23 20:55:23 -03:00
Alex Szpakowski 0f986b10aa Cleaned up some code, the 'ry' parameter of love.graphics.rectangle now defaults to the value of 'rx' rather than defaulting to 0. 2015-05-27 17:36:27 -03:00
Alex Szpakowski c62b005ff3 Changed the default mipmap filter to be 'linear' instead of 'nearest'. 2015-04-13 12:51:48 -03:00

Alex Szpakowski a29b349014 Added love.math.compress(data, format [, level]) and love.math.decompress(compresseddata) / love.math.decompress(compressedstring, format).
Renamed the love.image CompressedData type to CompressedImageData.

love.math.compress returns a love.math CompressedData object which holds the newly compressed data. Currently supported formats are "lz4" and "zlib". Note that the formats are not file formats and don't compress filesystem hierarchies.

Alex Szpakowski 06ef263537 Added OpenGL debug groups for most graphics operations when love is built in debug mode for iOS. The Xcode frame capture tool uses them to create nice visual groups for OpenGL function calls. 2015-03-16 22:55:58 -03:00
Alex Szpakowski 4ef0d257e9 Added an optional font hinting argument to love.graphics.newFont / love.font.newRasterizer when loading TrueType fonts. Resolves issue #963.
Accepted values are "normal", "light", "mono", and "none".

Alex Szpakowski 8067d42df2 Canvases now have OpenGL ES support, updated Texture:setWrap to return false for repeat wrap modes in non-power-of-two textures if OpenGL ES 2 is used and the implementation doesn't have support for repeat on NPOT textures.

Alex Szpakowski 3a51f0ad08 Changed the love.graphics internal code to always use a default shader when none is set externally, and replaced the deprecated OpenGL vertex attribute code with the equivalent generic vertex attribute functions.
This will simplify the code and make it more maintainable when OpenGL ES 2+ support is added, compared to using the deprecated VA functions on desktop GL and the generic VA functions on GLES.

Alex Szpakowski 8ffe610659 Added love.graphics.getStats. It returns a table with performance-related graphics statistics. Currently it contains these fields:
drawcalls: The number of internal draw calls made so far in the current frame.

canvasswitches: The number of times the active Canvas has been changed so far in the current frame.

texturememory: The approximate amount of video memory (in bytes) used by OpenGL textures created by Images, Canvases, and Fonts.

images: The number of active Image objects.

canvases: The number of active Canvas objects.

fonts: The number of active Font objects.

Alex Szpakowski afc505e183 Added stack type enums to love.graphics.push (resolves issue #906.) Current enums are "transform" and "all". "transform" is the default (for compatibility.) When love.graphics.push("all") is used, love.graphics.pop() will restore all love.graphics module state to what it was when push was called.
Updated the graphics code to use a custom matrix stack rather than OpenGL1's APIs.

Alex Szpakowski 8483ea31a1 Changed love.graphics.newImage's optional second argument to be a table of flags. Current flags are 'mipmaps' and 'srgb'.
If mipmaps are enabled on image creation, the image will use the default mipmap filter (now 'nearest' by default.) Image:setMipmapFilter will error if the image was not created with mipmaps enabled.

The list includes RGBA with 4-bit components, RGBA with 10-bit R, G, and B components and a 2-bit alpha component, RGB with 9-bit RGB components and a 5-bit exponent component (for HDR rendering), and several more.

Alex Szpakowski ce4fdf4ac9 Added sRGB (gamma-correct) support for Images, Canvases, and the main screen.
love.graphics.newImage(path, “srgb”) creates a new Image whose texels are treated as being in the sRGB color space, so they are linearized when drawing/sampling from the image.

love.graphics.newCanvas(w, h, “srgb”) creates a new Canvas whose texels are treated as being in the sRGB color space, so drawing to the Canvas does a linear->sRGB conversion (but blends linearly), and sampling from it (drawing it or using it in a shader) converts from sRGB to linear space.

The "srgb" window flag does the same as Canvases for the main screen.

Alex Szpakowski aa69a695d3 Canvases can now be used in SpriteBatches, ParticleSystems, and Meshes (resolves issue #782).
Canvases and Images are now subclasses of the new Texture class.
Added setTexture and getTexture methods for Meshes, ParticleSystems, and SpriteBatches (the old set/getImage methods are deprecated but not removed.)
Canvas texture coordinates are no longer flipped.
