Image
Image I/O and SKBitmap-Tensor conversion.
| Function | Description |
|---|---|
fromTensor tensor | Convert a [3, H, W] float32 tensor in [0, 1] to an SKBitmap. |
load path device | Load an image file as a [3, H, W] float32 tensor in [0, 1]. |
loadStream stream device | Load an image from a stream as a [3, H, W] float32 tensor in [0, 1]. |
save tensor path format _quality | Save a [3, H, W] float32 tensor as an image file. |
saveGrid tensor path format quality nrow | Save a batch tensor [N, C, H, W] as a grid image with nrow images per row. |
toTensor bitmap device | Convert an SKBitmap to a [3, H, W] float32 tensor in [0, 1]. |
| Alpha channel is discarded; output has 3 channels (RGB). |
