ImageViewer использует настройки рендеринга из свойства VintasoftImage.RenderingSettings для рендеринга изображения, если значение свойства ImageViewer.ImageRenderingSettings равно null.

Вот C#/VB.NET код, который демонстрирует, как загрузить 2 PDF документа с разными настройками рендеринга в ImageViewer:


// disable management of rendering settings in ImageViewer
imageViewer1.ImageRenderingSettings = null;

// create temporary image collection
Vintasoft.Imaging.ImageCollection images = new Vintasoft.Imaging.ImageCollection();
// add all pages of the first PDF document to temporary image collection
images.Add("testFile1.pdf");
// for each image in temporary image collection
for (int i = 0; i < images.Count; i++)
    // change rendering settings of image
    images[i].RenderingSettings.Resolution = new Vintasoft.Imaging.Resolution(300, 300);

// add images from temporary image collection to the image viewer
imageViewer1.Images.AddRange(images.ToArray());

// clear temporary image collection
images.Clear();
// add all pages of the second PDF document to temporary image collection
images.Add("testFile2.pdf");
// for each image in temporary image collection
for (int i = 0; i < images.Count; i++)
    // change rendering settings of image
    images[i].RenderingSettings.Resolution = new Vintasoft.Imaging.Resolution(100, 100);

// add images from temporary image collection to the image viewer
imageViewer1.Images.AddRange(images.ToArray());

VB.NET


' disable management of rendering settings in ImageViewer
imageViewer1.ImageRenderingSettings = Nothing

' create temporary image collection
Dim images As New Vintasoft.Imaging.ImageCollection()
' add all pages of the first PDF document to temporary image collection
images.Add("testFile1.pdf")
' for each image in temporary image collection
For i As Integer = 0 To images.Count - 1
    ' change rendering settings of image
    images(i).RenderingSettings.Resolution = New Vintasoft.Imaging.Resolution(300, 300)
Next

' add images from temporary image collection to the image viewer
imageViewer1.Images.AddRange(images.ToArray())

' clear temporary image collection
images.Clear()
' add all pages of the second PDF document to temporary image collection
images.Add("testFile2.pdf")
' for each image in temporary image collection
For i As Integer = 0 To images.Count - 1
    ' change rendering settings of image
    images(i).RenderingSettings.Resolution = New Vintasoft.Imaging.Resolution(100, 100)
Next

' add images from temporary image collection to the image viewer
imageViewer1.Images.AddRange(images.ToArray())
