Detailed Description

Todo:
use our own longjmp instead of libpng's. this way we don't need to use PNG_SETJMP_SUPPORTED in Windows, and don't depend on png_ptr->jmpbuf in older versions of libpng.

const char* GetVersion (    )  [inline]
 

Return the Corona version string.

Returns:
Corona version information

Definition at line 391 of file corona.h.

FileFormatDesc** GetSupportedReadFormats (    )  [inline]
 

Returns a null-terminated array of FileFormatDesc* pointers that describe the file formats Corona can read. The array is owned by Corona, so do not delete it when you are done using it.

Definition at line 401 of file corona.h.

FileFormatDesc** GetSupportedWriteFormats (    )  [inline]
 

Returns a null-terminated array of FileFormatDesc* pointers that describe the file formats Corona can write. The array is owned by Corona, so do not delete it when you are done using it.

Definition at line 410 of file corona.h.

Image* CreateImage (  int    width,
int    height,
PixelFormat    format,
void *    pixels = 0
)  [inline]
 

Create a new, blank image with a specified width, height, and format. If pixels is specified, Corona uses them to initialize the contents of the image. Corona does *not* take ownership of the pixel memory, so the caller is responsible for cleaning up after itself. If pixels is not specified, the new image is filled with zeroes.

Parameters:
width width of the new image
height height of the new image
format format the pixels are stored in, cannot be PF_DONTCARE
pixels pixel buffer used to initialize the new image
Returns:
newly created blank image

Image* CreateImage (  int    width,
int    height,
PixelFormat    format,
int    palette_size,
PixelFormat    palette_format
)  [inline]
 

Create a new, blank image with a specified width, height, format, and palette.

Parameters:
width width of image
height height of image
format format of palette indices, should be PF_I8
palette_size number of colors in palette
palette_format pixel format of palette entries

Image* CloneImage (  Image *    source,
PixelFormat    format = PF_DONTCARE
)  [inline]
 

Create a new image from an old one. If format is specified, the new image is converted to that pixel format. If format is not specified, the new image simply uses the same format as the source. If the image could not be cloned or the pixel format is invalid, CloneImage returns 0.

Parameters:
source image to clone
format format the new image is stored in, defaults to PF_DONTCARE
Returns:
new image cloned from the source, 0 if failure

Image* OpenImage (  const char *    filename,
PixelFormat    pixel_format = PF_DONTCARE,
FileFormat    file_format = FF_AUTODETECT
)  [inline]
 

Opens an image from the default filesystem. This function simply forwards the call to OpenImage(file, file_format, pixel_format) with a standard C library file.

See OpenImage(fs, filename, file_format, pixel_format) for more information.

Parameters:
filename image filename to open
file_format file format the image is stored in, or FF_AUTODETECT to try all loaders
pixel_format desired pixel format, or PF_DONTCARE to use image's native format
Returns:
the image loaded from the disk, or 0 if it cannot be opened

Image* OpenImage (  File *    file,
PixelFormat    pixel_format = PF_DONTCARE,
FileFormat    file_format = FF_AUTODETECT
)  [inline]
 

Opens an image from the specified file.

If file_format is FF_AUTODETECT, the loader tries to load each format until it finds one that succeeds. Otherwise, it tries the specific loader specified.

If pixel_format is PF_DONTCARE, the new image object has the pixel format closest to the image's format on disk. Otherwise, the pixels are converted to the specified format before the image is returned.

Parameters:
file name of the file that contains the image
file_format file format the image is stored in, or FF_AUTODETECT to try all loaders
pixel_format desired pixel format, or PF_DONTCARE to use image's native format
Returns:
the image loaded from the file, or 0 if it cannot be opened

bool SaveImage (  const char *    filename,
FileFormat    file_format,
Image *    image
)  [inline]
 

Saves an image to a file in the default filesystem. This function simply calls SaveImage(file, file_format, image) with a standard C library file.

See SaveImage(fs, filename, file_format, image) for more information.

Parameters:
filename name of the file to save the image to
file_format file format in which to save image. if FF_AUTODETECT, SaveImage guesses the type from the file extension
image image to save
Returns:
true if save succeeds, false otherwise

References corona::hidden::file_format, FileFormat, and corona::hidden::image.

bool SaveImage (  File *    file,
FileFormat    file_format,
Image *    image
)  [inline]
 

Saves an image to the specified file. This function saves image to a file of type file_format. If file_format is not a supported output type, the function fails. As of now, Corona only supports saving images of type FF_PNG and FF_TGA.

Note:
This function may create the file even if the save does not succeed, so users of this library should remove the file after the call to SaveImage().
Parameters:
file file in which to save the image
file_format file format in which to save image -- must not be FF_AUTODETECT
image image to save
Returns:
true if the save succeeds, false otherwise

References corona::hidden::file_format, FileFormat, and corona::hidden::image.

Image* ConvertImage (  Image *    source,
PixelFormat    format
)  [inline]
 

Converts an image from one format to another, destroying the old image. If source is 0, the function returns 0. If format is PF_DONTCARE or the source and target formats match, returns the unmodified source image. If a valid conversion is not found, ConvertImage destroys the old image and returns 0. For example, ConvertImage does not support creating a palettized image from a direct color image yet.

Parameters:
source image to convert
format desired format -- can be PF_DONTCARE
Returns:
valid image object if conversion succeeds, 0 otherwise

Image* ConvertPalette (  Image *    source,
PixelFormat    palette_format
)  [inline]
 

Converts the palette of a palettized image from one format to another, destroying the old image. If the source is 0, the palette_format is PF_DONTCARE, or the source and target formats match, the function returns the unmodified source image. If a valid conversion is not found or invalid inputs are given (such as a direct-color source image), this function destroys the old image and returns 0.

Parameters:
source palettized image to convert
palette_format desired pixel format of palette
Returns:
valid image object if conversion succeeds, 0 otherwise

Image* FlipImage (  Image *    source,

)  [inline]
 

Flips the pixels in the image around the given axis.

Parameters:
source image to flip
coordinate_axis Axis around which to flip. Both CA_X and CA_Y can be specified by ORing them together.
Returns:

File* CreateMemoryFile (  const void *    buffer,
int    size
)  [inline]
 

Creates a File implementation that reads from a buffer in memory. It stores a copy of the buffer that is passed in.

The File object does not take ownership of the memory buffer. When the file is destroyed, it will not free the memory.

Parameters:
buffer Pointer to the beginning of the data.
size Size of the buffer in bytes.
Returns:
0 if size is non-zero and buffer is null. Otherwise, returns a valid File object.
