LoadPsdLayer Method (original) (raw)
Summary
Loads the specified layer from the specified PSD file.
Syntax
Parameters
fileName
A String containing the name of the image file to load.
bitsPerPixel
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. |
order
The desired color order.
layer
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.
layerInfo
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.
Example
This example will create and save a PSD with layers before re-loading the first layer back
