Detailed Description

Each GIMP image is composed of one or more layers. A layer can be one of any three basic types: RGB, grayscale or indexed. With an optional alpha channel, there are six possible types altogether.

Note: there is only ever one instance of this structure. The layer info is discarded after it is merged into the final QImage.

Member Data Documentation

bool XCFImageFormat::Layer::active

Is this layer the active layer?

Definition at line 92 of file xcf.h.

Tiles XCFImageFormat::Layer::alpha_tiles

For Grayscale and Indexed images, the alpha channel is stored separately (in this data structure, anyway).

Definition at line 80 of file xcf.h.

Q_UINT32 XCFImageFormat::Layer::apply_mask

Apply the layer mask?

Definition at line 97 of file xcf.h.

void(* XCFImageFormat::Layer::assignBytes)(Layer &layer, uint i, uint j)

The data from tile buffer is copied to the Tile by this method.

Depending on the type of the tile (RGB, Grayscale, Indexed) and use (image or mask), the bytes in the buffer are copied in different ways.

Definition at line 112 of file xcf.h.

Q_UINT32 XCFImageFormat::Layer::edit_mask

Is the layer mask the being edited?

Definition at line 98 of file xcf.h.

Q_UINT32 XCFImageFormat::Layer::height

Height of the layer.

Definition at line 68 of file xcf.h.

Q_UINT32 XCFImageFormat::Layer::hierarchy_offset

File position of Tile hierarchy.

Definition at line 71 of file xcf.h.

Tiles XCFImageFormat::Layer::image_tiles

The basic image.

Definition at line 77 of file xcf.h.

Q_UINT32 XCFImageFormat::Layer::linked

Is this layer linked (geometrically)

Definition at line 95 of file xcf.h.

struct { ... } XCFImageFormat::Layer::mask_channel

Additional information about a layer mask.

Q_UINT32 XCFImageFormat::Layer::mask_offset

File position of mask image.

Definition at line 72 of file xcf.h.

Tiles XCFImageFormat::Layer::mask_tiles

The layer mask (optional)

Definition at line 81 of file xcf.h.

Q_UINT32 XCFImageFormat::Layer::mode

Combining mode of layer (LayerModeEffects)

Definition at line 102 of file xcf.h.

char* XCFImageFormat::Layer::name

Name of the layer.

Definition at line 70 of file xcf.h.

uint XCFImageFormat::Layer::ncols

Number of columns of tiles (x direction)

Definition at line 75 of file xcf.h.

uint XCFImageFormat::Layer::nrows

Number of rows of tiles (y direction)

Definition at line 74 of file xcf.h.

Q_UINT32 XCFImageFormat::Layer::opacity

The opacity of the layer.

Definition at line 85 of file xcf.h.

Q_UINT32 XCFImageFormat::Layer::preserve_transparency

Preserve alpha when drawing on layer?

Definition at line 96 of file xcf.h.

Q_UINT32 XCFImageFormat::Layer::show_mask

Show the layer mask rather than the image?

Definition at line 99 of file xcf.h.

Q_UINT32 XCFImageFormat::Layer::tattoo

(unique identifier?)

Definition at line 89 of file xcf.h.

uchar XCFImageFormat::Layer::tile[TILE_WIDTH *TILE_HEIGHT *sizeof(QRgb)]

As each tile is read from the file, it is buffered here.

Definition at line 106 of file xcf.h.

Q_INT32 XCFImageFormat::Layer::type

Type of the layer (GimpImageType)

Definition at line 69 of file xcf.h.

Q_UINT32 XCFImageFormat::Layer::visible

Is the layer visible?

Definition at line 86 of file xcf.h.

Q_UINT32 XCFImageFormat::Layer::width

Width of the layer.

Definition at line 67 of file xcf.h.

Q_INT32 XCFImageFormat::Layer::x_offset

x offset of the layer relative to the image

Definition at line 100 of file xcf.h.

Q_INT32 XCFImageFormat::Layer::y_offset

y offset of the layer relative to the image

Definition at line 101 of file xcf.h.
