anonymous enum |
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_BOX_AVERAGE |
Use surrounding pixels to calculate an average that will be used for new pixels. This method is typically used when reducing the size of an image. |
wxIMAGE_QUALITY_NORMAL |
Default image resizing algorithm used by wxImage::Scale(). Currently the same as wxIMAGE_QUALITY_NEAREST. |
wxIMAGE_QUALITY_HIGH |
Best image resizing algorithm. Since version 2.9.2 this results in wxIMAGE_QUALITY_BOX_AVERAGE being used when reducing the size of the image (meaning that both the new width and height will be smaller than the original size). Otherwise wxIMAGE_QUALITY_BICUBIC is used. |
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_THRESHOLD = 0x80 |
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.
