LoadPsdLayer Method

Loads the specified layer from the specified PSD file.
Public Function LoadPsdLayer( _ 
   ByVal fileName As String, _ 
   ByVal bitsPerPixel As Integer, _ 
   ByVal order As CodecsLoadByteOrder, _ 
   ByVal layer As Integer, _ 
   ByVal layerInfo As CodecsPsdLayerInfo _ 
) As RasterImage 


A String containing the name of the image file to load.

Resulting image pixel depth. Valid values are:

Value Meaning
0 Keep the original file's pixel depth (Do not convert).
1 to 8 The specified bits per pixel in the resulting image.
12 12 bits per pixel in the resulting image.
16 16 bits per pixel in the resulting image.
24 24 bits per pixel in the resulting image.
32 32 bits per pixel in the resulting image.
48 48 bits per pixel in the resulting image.
64 64 bits per pixel in the resulting image.

The desired color order.

Index of the layer to load. This index is zero-based. Pass 0 to load the first layer, 1 to load the second layer, etc.

a CodecsPsdLayerInfo object to be updated with information about the loaded layer. Pass a null reference for this parameter if layer information is not needed.

Return Value

The RasterImage object that this method loads.


Use this method to load PSD files only.

This method works similarly to a normal Load or LoadAsync methods, except that it loads only a layer from a PSD file. It loads the layer specified in layer.

Before calling this method, you may need to get or set file information, such as the number of layers on the file. Refer to CodecsPsdImageInfo.

The number of layers in a file is indicated in CodecsPsdImageInfo.Layers. If this number is 0, the file does not contains any layers and this method should not be called.


This example will create and save a PSD with layers before re-loading the first layer back
