Enumeration Type Documentation
| anonymous enum |
| enum wxImagePNGType |
Possible values for PNG image type option.
- See also
- wxImage::GetOptionInt().
| Enumerator | |
|---|---|
| wxPNG_TYPE_COLOUR |
Colour PNG image. |
| wxPNG_TYPE_GREY |
Greyscale PNG image converted from RGB. |
| wxPNG_TYPE_GREY_RED |
Greyscale PNG image using red as grey. |
| wxPNG_TYPE_PALETTE |
Palette encoding. |
| enum wxImageResizeQuality |
Image resize algorithm.
This is used with wxImage::Scale() and wxImage::Rescale().
| Enumerator | |
|---|---|
| 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.
- See also
- wxImage::GetOptionInt().
| Enumerator | |
|---|---|
| wxIMAGE_RESOLUTION_NONE |
Resolution not specified. |
| wxIMAGE_RESOLUTION_INCHES |
Resolution specified in inches. |
| wxIMAGE_RESOLUTION_CM |
Resolution specified in centimetres. |
