rectangle | Rectangle | The rectangle to load pixels from. |
Return Value
The loaded pixels array.
Examples
This example shows how to Loads Pixel information in an Array of Type Color, manipulates the array and set it back to the image. To perform these operations, this example creates a new Image file (in PSD format) using MemoryStream object.
[C#]
//Create an instance of MemoryStream
using (System.IO.MemoryStream stream = new System.IO.MemoryStream())
{
//Create an instance of PsdOptions and set its various properties including the Source property
Aspose.PSD.ImageOptions.PsdOptions psdOptions = new Aspose.PSD.ImageOptions.PsdOptions();
psdOptions.Source = new Aspose.PSD.Sources.StreamSource(stream);
//Create an instance of Image
using (Aspose.PSD.RasterImage image = (Aspose.PSD.RasterImage)Aspose.PSD.Image.Create(psdOptions, 500, 500))
{
//Get the pixels of image by specifying the area as image boundary
Aspose.PSD.Color[] pixels = image.LoadPixels(image.Bounds);
//Loop over the Array and sets color of alrenative indexed pixel
for (int index = 0; index < pixels.Length; index++)
{
if (index % 2 == 0)
{
//Set the indexed pixel color to yellow
pixels[index] = Aspose.PSD.Color.Yellow;
}
else
{
//Set the indexed pixel color to blue
pixels[index] = Aspose.PSD.Color.Blue;
}
}
//Apply the pixel changes to the image
image.SavePixels(image.Bounds, pixels);
// save all changes.
image.Save();
}
//Write MemoryStream to File
stream.WriteTo(new System.IO.FileStream(@"C:\temp\output.psd", System.IO.FileMode.CreateNew));
