PdfPageImageTexture class abstract

Very limited support for Flutter's Texture based drawing. Because it does not transfer the rendered image via platform channel, it could be faster and more efficient than the PdfPageImage based rendrering process.

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}) → Future<bool>
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.

Operators

operator ==(Object other) → bool
The equality operator.

Static Methods

create({required PdfDocument pdfDocument, required int pageNumber}) → Future<PdfPageImageTexture>
Create a new Flutter Texture. The object should be released by calling dispose method after use it.
