THotPDF.GetRenderBackendStatistics

复制累计的后端执行计数器和最近一次的执行结果

声明

function GetRenderBackendStatistics(
  out Statistics: THPDFRenderBackendStatistics): boolean;

参数

Statistics receives attempts, successes, failures, fallbacks, serialised calls, last elapsed milliseconds, backend name, and failure reason

返回值

True when at least one assigned-backend request has been attempted, otherwise False

使用说明

统计信息在文档渲染锁的保护下更新
后端失败后由软件渲染成功接手时，FailureCount 和 FallbackCount 都会加一
Direct default-renderer calls made while PageRenderBackend 是 nil do not increment these counters
