wxImage & Rescale (int width, int height, wxImageResizeQuality quality=wxIMAGE_QUALITY_NORMAL)
Changes the size of the image in-place by scaling it: after a call to this function,the image will have the given width and height.
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.
Around line 4322 in wxeud.e
public constant wxIMAGE_QUALITY_NORMAL = 0, wxIMAGE_QUALITY_HIGH = 1
