updateRect method

Future<bool> updateRect({ int destX = 0, int destY = 0, int? width, int? height, int srcX = 0, int srcY = 0, int? texWidth, int? texHeight, double? fullWidth, double? fullHeight, bool backgroundFill = true, })

Update texture's sub-rectangle (destX,destY,width,height) with the sub-rectangle (srcX,srcY,width,height) of the PDF page scaled to fullWidth x fullHeight size. If backgroundFill is true, the sub-rectangle is filled with white before rendering the page content. The method can also resize the texture if you specify texWidth and texHeight. Returns true if succeeded.

Implementation

Future<bool> updateRect({int destX = 0, int destY = 0, int? width, int? height, int srcX = 0, int srcY = 0, int? texWidth, int? texHeight, double? fullWidth, double? fullHeight, bool backgroundFill = true}) async {
  final result = await (_channel.invokeMethod<int>('updateTex', {
