GstVideoScale Scale a video buffer This library implements a scaling algorithm for video buffers. the different scaling methods available. @GST_VIDEOSCALE_POINT_SAMPLE: perform a point sample filter @GST_VIDEOSCALE_NEAREST: use a nearest neighbor algorithm @GST_VIDEOSCALE_BILINEAR: use a bilinear filter @GST_VIDEOSCALE_BICUBIC: use a bicubic filter @source_width: @source_height: @dest_width: @dest_height: @format: @method: @copy_row: @temp: @scale: @scaler: @filter: the actual scaler implementation @scale: @src: @dest: Create a new video scaler @sw: the width of the source bitmap @sh: the height of the source bitmap @dw: the width of the destination bitmap @dh: the height of the destination bitmap @format: the format of the source and destination bitmaps @method: the filter method @Returns: a new scaler Perform the scale @scaler: the scaler @src: the source buffer @dest: the destination buffer Destroy the scaler @scale: the scaler to destroy
