picLayer (Variable type)

In french: picCalque

The picLayer type is used to define all the advanced characteristics of a layer of an image loaded in a WDPic variable. You can define and change the characteristics of this layer using different WLanguage properties.

Note: For more details on the declaration of this type of variable and the use of WLanguage properties, see Declaring a variable.

Example

// Ouverture d'une image source
MonImage is WDPic
MonImage.FileName = fExeDir() + ["\"] + "Source.png"
// Ajout d'un calque contenant un rectangle
CalqueRectangle is picLayer
CalqueRectangle.Name = "Rectangle"
CalqueRectangle.Width = 100
CalqueRectangle.Height = 100
dRectangle(CalqueRectangle, 1, 1, 50, 50, DarkGreen, DarkBlue)
// Rotation du calque
dRotation(CalqueRectangle, 45, drAdapt)
CalqueRectangle.X = nXCalque
CalqueRectangle.Y = nYCalque
Add(MonImage.Layer, CalqueRectangle)
// Sauvegarde du résultat
PicSave(MonImage, fExeDir() + ["\"] + "Resultat.png")

Properties

Properties specific to picLayer variables

The following properties can be used to handle a layer of a WDPic image:

Property name	Type used	Effect

Height	Integer	Layer height expressed in pixels.
Image		Image associated with layer. If this property is specified, the Type property will correspond to the typeLayerImage constant.
Name	Character string	Layer name.
RTF	picRTF variable	String in Rich Text Format.
Text	picText variable	Layer text. The properties of the picText variable are used to find out and define the options of the text (font, opacity, alignment, etc.).
Type	Integer constant	Type of layer: typeImageLayer: Image type layer. The Image property gets and sets the image associated with the layer. typeLayerRTF: RTF-type layer. The RTF property gets and sets the content of the layer. typeTextLayer: Text layer. The Text property gets and sets the text associated with the layer.
Visible	Boolean	True if the layer is visible, False if the layer is invisible.
Width	Integer	Layer width expressed in pixels.
X	Integer	Horizontal position of layer on the image, expressed in pixels.
Y	Integer	Vertical position of layer on the image, expressed in pixels.
