Classes | |
class | wxImageHandler |
This is the base class for implementing image file loading/saving, and image creation from data. More... | |
class | wxImage |
This class encapsulates a platform-independent image. More... | |
class | wxImage::RGBValue |
A simple class which stores red, green and blue values as 8 bit unsigned integers in the range of 0-255. More... | |
class | wxImage::HSVValue |
A simple class which stores hue, saturation and value as doubles in the range 0.0-1.0. More... | |
Enumerations | |
enum | wxImageResolution { wxIMAGE_RESOLUTION_NONE = 0, wxIMAGE_RESOLUTION_INCHES = 1, wxIMAGE_RESOLUTION_CM = 2 } |
Possible values for the image resolution option. More... | |
enum | wxImageResizeQuality { wxIMAGE_QUALITY_NEAREST, wxIMAGE_QUALITY_BILINEAR, wxIMAGE_QUALITY_BICUBIC, wxIMAGE_QUALITY_NORMAL, wxIMAGE_QUALITY_HIGH } |
Image resize algorithm. More... | |
enum | wxImagePNGType { wxPNG_TYPE_COLOUR = 0, wxPNG_TYPE_GREY = 2, wxPNG_TYPE_GREY_RED = 3 } |
Possible values for PNG image type option. More... | |
Functions | |
void | wxInitAllImageHandlers () |
Initializes all available image handlers. | |
Variables | |
const unsigned char | wxIMAGE_ALPHA_TRANSPARENT = 0 |
Constant used to indicate the alpha value conventionally defined as the complete transparency. | |
const unsigned char | wxIMAGE_ALPHA_OPAQUE = 0xff |
Constant used to indicate the alpha value conventionally defined as the complete opacity. | |
wxImage | wxNullImage |
An instance of an empty image without an alpha channel. |
enum wxImagePNGType |
Possible values for PNG image type option.
enum wxImageResizeQuality |
Image resize algorithm.
This is used with wxImage::Scale() and wxImage::Rescale().
wxIMAGE_QUALITY_NEAREST |
Simplest and fastest algorithm. |
wxIMAGE_QUALITY_BILINEAR |
Compromise between wxIMAGE_QUALITY_NEAREST and wxIMAGE_QUALITY_BICUBIC. |
wxIMAGE_QUALITY_BICUBIC |
Highest quality but slowest execution time. |
wxIMAGE_QUALITY_NORMAL |
Default image resizing algorithm used by wxImage::Scale(). |
wxIMAGE_QUALITY_HIGH |
Best image resizing algorithm, currently same as wxIMAGE_QUALITY_BICUBIC. |
enum wxImageResolution |
Possible values for the image resolution option.
const unsigned char wxIMAGE_ALPHA_OPAQUE = 0xff |
Constant used to indicate the alpha value conventionally defined as the complete opacity.
const unsigned char wxIMAGE_ALPHA_TRANSPARENT = 0 |
Constant used to indicate the alpha value conventionally defined as the complete transparency.
An instance of an empty image without an alpha channel.
