Scale the image slice in srcSlice and put the resulting scaled slice in the image in dst. A slice is a sequence of consecutive rows in an image. Slices have to be provided in sequential order, either in top-bottom or bottom-top order. If slices are provided in non-sequential order the behavior of the function is undefined.

Parameters:
c - the scaling context previously created with sws_getContext()
srcSlice - the array containing the pointers to the planes of the source slice
srcStride - the array containing the strides for each plane of the source image
srcSliceY - the position in the source image of the slice to process, that is the number (counted starting from zero) in the image of the first row of the slice
srcSliceH - the height of the source slice, that is the number of rows in the slice
dst - the array containing the pointers to the planes of the destination image
dstStride - the array containing the strides for each plane of the destination image

Returns:
the height of the output slice

Check if context can be reused, otherwise reallocate a new one. If context is NULL, just calls sws_getContext() to get a new context. Otherwise, checks if the parameters are the ones already saved in context. If that is the case, returns the current context. Otherwise, frees context and gets a new context with the new parameters. Be warned that srcFilter and dstFilter are not checked, they are assumed to remain the same.

Convert an 8-bit paletted frame into a frame with a color depth of 32 bits. The output frame will have the same packed format as the palette.

Parameters:: src - source frame buffer; dst - destination frame buffer; num_pixels - number of pixels to convert; palette - array with [256] entries, which must match color arrangement (RGB or BGR) of src

Convert an 8-bit paletted frame into a frame with a color depth of 24 bits. With the palette format "ABCD", the destination frame ends up with the format "ABC".

Parameters:: src - source frame buffer; dst - destination frame buffer; num_pixels - number of pixels to convert; palette - array with [256] entries, which must match color arrangement (RGB or BGR) of src
