GetImage()

Slide::GetImage(float, float) method

Returns a Thumbnail Image object with custom scaling.

System::SharedPtr<IImage> Aspose::Slides::Slide::GetImage(float scaleX, float scaleY) override

Arguments

ParameterTypeDescription
scaleXfloatThe value by which to scale this Thumbnail in the x-axis direction.
scaleYfloatThe value by which to scale this Thumbnail in the y-axis direction.

Return Value

IImage object.

Remarks

The following example shows how to generate thumbnails from PowerPoint Presentation:

System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>(u"ThumbnailFromSlide.pptx");

// Access the first slide
System::SharedPtr<ISlide> sld = pres->get_Slide(0);
// Create a full scale image
System::SharedPtr<IImage> bmp = sld->GetImage(1.0f, 1.0f);
// Save the image to disk in JPEG format
bmp->Save(u"Thumbnail_out.jpg", Aspose::Slides::ImageFormat::Jpeg);

The following example shows how to converting slides to bitmap and saving the images in PNG:

System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>(u"Presentation.pptx");

// Converts the first slide in the presentation to a Bitmap object
System::SharedPtr<IImage> bmp = pres->get_Slide(0)->GetImage();
// Saves the image in the PNG format
bmp->Save(u"Slide_0.png", Aspose::Slides::ImageFormat::Png);

The following example shows how to convert PowerPoint PPT/PPTX to JPG:

System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>(u"PowerPoint-Presentation.ppt");

for (auto&& sld : pres->get_Slides())
{
    // Create a full scale image
    System::SharedPtr<IImage> bmp = sld->GetImage(1.f, 1.f);
    // Save the image to disk in JPEG format
    bmp->Save(System::String::Format(u"Slide_{0}.jpg", sld->get_SlideNumber()), Aspose::Slides::ImageFormat::Jpeg);
}

The following example shows how to convert PowerPoint PPT/PPTX to JPG with customized dimensions:

System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>(u"PowerPoint-Presentation.pptx");

// Define dimensions
int32_t desiredX = 1200;
int32_t desiredY = 800;
// Get scaled values of X and Y
float scaleX = (float)(1.0 / pres->get_SlideSize()->get_Size().get_Width()) * desiredX;
float scaleY = (float)(1.0 / pres->get_SlideSize()->get_Size().get_Height()) * desiredY;

for (auto&& sld : pres->get_Slides())
{
    // Create a full scale image
    System::SharedPtr<IImage> bmp = sld->GetImage(scaleX, scaleY);
    // Save the image to disk in JPEG format
    bmp->Save(System::String::Format(u"Slide_{0}.jpg", sld->get_SlideNumber()), Aspose::Slides::ImageFormat::Jpeg);
}

Remarks

The following example shows how to converting slides to images with custom sizes using C#.

System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>(u"Presentation.pptx");

// Converts the first slide in the presentation to a Bitmap with the specified size
System::SharedPtr<IImage> bmp = pres->get_Slide(0)->GetImage(System::Drawing::Size(1820, 1040));

// Saves the image in the JPEG format
bmp->Save(u"Slide_0.jpg", Aspose::Slides::ImageFormat::Jpeg);

Remarks

The following example shows how to converting slides With notes and comments to Images using C#.

System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>(u"PresentationNotesComments.pptx");

// Create the rendering options
System::SharedPtr<IRenderingOptions> options = System::MakeObject<RenderingOptions>();
// Create notes and comments layouting options
System::SharedPtr<NotesCommentsLayoutingOptions> notesCommentsLayouting = System::MakeObject<NotesCommentsLayoutingOptions>();
// Sets the position of the notes on the page
notesCommentsLayouting->set_NotesPosition(NotesPositions::BottomTruncated);
// Sets the position of the comments on the page
notesCommentsLayouting->set_CommentsPosition(CommentsPositions::Right);
// Sets the width of the comment output area
notesCommentsLayouting->set_CommentsAreaWidth(500);
