object.pixelWidth

概述

指示图像宽度（以像素为单位）的整数。

您可以将此属性的像素宽度转换为 Corona与内容相适应的坐标（相对于在 config.lua 文件中设置的内容宽度和高度），方法是将此属性乘以 display.contentScaleX 属性。

示例

local steamworks = require( "plugin.steamworks" )

-- Fetch information about the logged in user's medium avatar image
local imageInfo = steamworks.getUserImageInfo( "avatarMedium" )

if ( imageInfo ) then
    -- Print the avatar size in pixels
    local message1 = string.format(
        "Medium Avatar Pixel Size: %dx%d",
        imageInfo.pixelWidth,
        imageInfo.pixelHeight )
    print( message1 )

    -- Print the avatar size in Corona's content scaled coordinates
    local message2 = string.format(
        "Medium Avatar Content Size: %dx%d",
        imageInfo.pixelWidth * display.contentScaleX,
        imageInfo.pixelHeight * display.contentScaleY )
    print( message2 )
end
