Normally DPI isn't specified in reolution but since some devices don't provide the means to query the actual DPI it is \"faked\" on those devices using the resolution.\n </p>\r\n <p>\n Notice that multi-images aren't intended for use as a replacement for scaling/tiling, or anything of that kind since that would become prohibitively expensive as the resource grows and would also be ineffective since phones tend to change their resolution during runtime e.g. by rotation or poping up some types of virtual keyboards.\n </p>\n <p>\n The multi-image is very similar in spirit to LWUIT's SVG support and is mostly targeted at designers who have raster images rather than vector resources or those who would normally target devices without SVG. \n </p>\n <p>\n Working with the multi-image is seamless and LWUIT will replace the images on loading during runtime (this is 100% seamless to developers). Use the combo box at the top to select the proper DPI/resolution and create an icon that would look decent in that resolution. Keep in mind that you do not need to support all resolutions and that LWUIT will pick the \"best\" image it can if none is defined for a specific DPI. E.g. if an image isn't defined for the very low resolution LWUIT will look to higher resolution resources until it finds an image. \n </p>\n </body>\r\n</html>\r\n"); // NOI18N
