Load(Uri,int,CodecsLoadByteOrder,int,int) Method (original) (raw)
Summary
Loads the specified image URL using specified options.
Syntax
Parameters
uri
The Uri containing the input image data.
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
Color order for 16-bit, 24-bit, 32-bit, 48-bit, and 64-bit images. If the resulting image is less than 16 bits per pixel, this will have no effect since palletized images have no order. The following are valid values.
| Value | Meaning |
|---|---|
| CodecsLoadByteOrder.Rgb | Red, green, and blue color order in memory |
| CodecsLoadByteOrder.Bgr | Blue, green, and red color order in memory |
| CodecsLoadByteOrder.Gray | 12 or 16-bit grayscale image. 12 and 16-bit grayscale images are only supported in the Document/Medical Imaging editions. |
| CodecsLoadByteOrder.RgbOrGray | Load the image as red, green, blue OR as a 12 or 16-bit grayscale image. 12 and 16-bit grayscale images are supported in the Document/Medical Imaging editions |
| CodecsLoadByteOrder.BgrOrGray | Load the image as blue, green, red OR as a 12 or 16-bit grayscale image. 12 and 16-bit grayscale images are supported in the Document/Medical Imaging editions |
| CodecsLoadByteOrder.Romm | ROMM order. ROMM only supports 24 and 48-bit images |
| CodecsLoadByteOrder.BgrOrGrayOrRomm | Load the image as red, green, blue OR as a 12 or 16-bit grayscale image OR as ROMM. 12 and 16-bit grayscale images are supported in the Document/Medical Imaging editions only. ROMM only supports 24 and 48-bit color images. |
firstPage
1-based index of the first page to load.
lastPage
The 1-based index of the last page to load. Must be greater than or equal to firstPage. You can pass -1 to load from firstPage to the last page in the file.
Return Value
The RasterImage object that this method loads.
Example
This example will load an image from a uri with different bits per pixel
using Leadtools;
using Leadtools.Codecs;
using Leadtools.ImageProcessing;
using Leadtools.ImageProcessing.Color;
using Leadtools.Svg;
public void LoadUri2Example()
{
RasterCodecs codecs = new RasterCodecs();
// Load the image with 1 bits/pixel
Uri uri = new Uri(@"https://www.leadtools.com/images/page_graphics/leadlogo.png");
RasterImage image = codecs.Load(uri, 1, CodecsLoadByteOrder.Rgb, 1, 1);
// Show information about tha image
Debug.WriteLine("Size: {0} by {1} pixels", image.Width, image.Height);
Debug.WriteLine("Bits/Pixel: {0}", image.BitsPerPixel);
image.Dispose();
// Clean up
codecs.Dispose();
}
