Luna::RHI::ICommandBuffer::copy_texture_to_buffer

virtual void copy_texture_to_buffer(IBuffer *dst, u64 dst_offset, u32 dst_row_pitch, u32 dst_slice_pitch, ITexture *src, SubresourceIndex src_subresource, u32 src_x, u32 src_y, u32 src_z, u32 copy_width, u32 copy_height, u32 copy_depth)=0

Copies texture data region from one texture to one buffer. Texture data is written to the buffer in row-major arrangement.

Parameters

• in dst

  The buffer to copy data to.

• in dst_offset

  The offset, in bytes, of the first data byte to copy data to in dst.

• in dst_row_pitch

  The number of bytes to advance between every row of data in dst.

• in dst_slice_pitch

  The number of bytes to advance between every slice (row * column) of data in dst.

• in src

  The texture to copy data from.

• in src_subresource

  The subresource in src to copy data from.

• in src_x

  The X position of the first pixel to copy data from.

• in src_y

  The Y position of the first pixel to copy data from.

• in src_z

  The Z position of the first pixel to copy data from.

• in copy_width

  The number of pixels to copy for each row.

• in copy_height

  The number of rows to copy for each slice.

• in copy_depth

  The number of slices to copy.
