LoadPsdChannel Method (original) (raw)
Summary
Loads the specified channel 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.
channelIndex
Index of the channel to load. This index is zero-based. Pass 0 to load the first channel, 1 to load the second channel, etc.
channelInfo
a CodecsPsdChannelInfo object to be updated with information about the loaded channel. Pass a null reference for this parameter if channel information is not needed.
Return Value
The RasterImage object that this method loads.
