| image | Specifies the image storage to load. If an image storage with the specified storage name (excluding extension) plus _m exists, it will be loaded as a mask (opacity) image. If an image storage with the specified storage name (excluding extension) plus _p exists, it will be loaded as a province (region) image. |
| colorkey | Specifies the color key (transparent color) for the image to be loaded. If a color is specified in 0xRRGGBB format, that color is used as the color key. If a value consisting of clPalIdx plus an arbitrary palette index is specified, that palette index becomes the transparent color (for images with 256 colors or less). If clAdapt is specified, the most frequently used color in the top line of the image automatically becomes the transparent color. If a value consisting of clAlphaMat plus a color in 0xRRGGBB format is specified, the image is overlaid on that color using alpha blending (ltAlpha method). For example, if (clAlphaMat + 0xffffff) is specified, the loaded image is overlaid on white. The resulting image will be completely opaque (Note that while the image becomes opaque, the tag information is not modified at all in this mode). |
