7.2. Nytt lag

The New Layer… command opens the Create a New Layer dialog that allows you to add a new, empty layer to the layer stack of the image, just above the active layer.

7.2.1. Aktivering

  • You can access this command from the image menubar through LayerNew Layer…, or by clicking on the dedicated button in the layer dialog.

Figur 16.100. Dialogvindauget for «Nytt lag»

Dialogvindauget for «Nytt lag»

Under tittelen «Opprett eit nytt lag» kan du sjå namnet på det biletet dette laget vert oppretta i. Oppe til høgre vert det vist ein miniatyr av dette biletet. Dette som ein kontroll på at du har vald det rette biletet når du har fleire framme på skjermen samstundes.

Namn på laget

Her kan du skrive inn eit namn på laget. Namnet vert ikkje brukt til anna enn å gjere det lettare for deg å halde styr på dei ulike laga. Dersom du ikkje skriv inn noko her, vil det nye laget få namnet «Nytt lag». Skulle du velje eit namn som er i bruk frå før, vert det lagt til eit tal, for eksempel «Nytt lag#1», når du klikkar på knappen OK.

Color tag

If you click on one of these color buttons, the "Eye" icon box of the created layer will have this color. This is interesting when you have many layers in the image.

Mode

Default is Normal. The drop-down list offers all layer blend modes. On the right, another drop-down list to select between Default or Legacy group of modes.

Layer blend modes are described in Layer Modes.

Blend space

The space used by the layer mode. This option is not activated.

Composite mode

The layer's mode (sometimes referred to as its blend mode: Normal, Multiply, etc.) determines how the color values of the layer and its backdrop are combined, while the layer's composite mode determines how the alpha values of the layer and its backdrop are combined. (The layer's backdrop is the content against which the layer is composited; namely, it's the combination of the layers below it.)

There are two regions of interest when compositing the layer against its backdrop: the opaque region of the backdrop, and the opaque region of the layer. The layer's blend mode determines how to combine the colors of the intersection of these two regions: i.e., the common opaque region of both the backdrop and the layer (pixels belonging to only one of these regions don't need to be combined with anything, and retain their original color.). The layer's composite mode determines which part of these regions to keep, and which to discard.

The example images below show the composition of two layers -- the bottom layer containing a red feathered circle, and the top layer containing a green feathered circle -- using Addition mode, and different composite modes (applied to the top layer).

  • Union: keeps the opaque regions of both the layer and its backdrop, i.e their union.

    Union option example

  • Clip to backdrop: keeps only the opaque regions of the backdrop (this includes the common opaque region to both the backdrop and the layer i.e their intersection).

  • Clip to layer: keeps only the opaque region of the layer (this includes the common opaque region to both the backdrop and the layer, i.e their intersection).

  • Intersection: keeps only the opaque region to both the backdrop and the layer, i.e their intersection.

    Figur 16.104. Intersection option example

    Intersection option example

  • Auto: Auto mode is not a separate composite mode, but rather corresponds to one of the other composite modes, depending on the layer's blend mode: for Normal, Dissolve, and Merge, it corresponds to Union, and for the other modes (that support different composite modes) it corresponds to Clip to Backdrop.

Composite space

Default is Auto. In the drop-down list, you can choose between RGB linear and RGB perceptual.

Channel encodings are described in Glossary.

Opacity

Sets the opacity of painting on the layer. Default is 100%.

Breidde og høgde

Dette bestemmer storleiken på det nye laget. Dersom forslaget som står i tekstboksane ikkje passer, kan du skrive inn nye tal eller bruke piltastane til høgre for tekstboksen.

Offset X; Y

The origin of the new layer is the upper left corner of the image. Here, you can set precisely the position of layers smaller than the canvas, especially text layers.

Fill With

There are five options for the solid color that fills the layer: the current Foreground color, the current Background color, White, Transparency, and Pattern.

Switches

These switches reproduce options described in the Layer Dialog.
