Set image size limits Leave feedback

GroupDocs.Viewer also provides the feature to set limits for width/height for the output image. Follow the below steps to achieve this functionality. If you want to render single image in PDF you can set width/height for the output image. If you set ImageMaxWidth/ImageMaxHeight options, if the image exceeds one of these limits - it will be resized proportionally.

Instantiate the Viewer object;
Instantiate the PdfViewOptions;
Set ImageMaxWidth and/or ImageMaxHeight values;
Call view() method.

The following code sample shows how to set the output image size limits when rendering the document.

try (Viewer viewer = new Viewer("sample.jpg")) {
    PdfViewOptions viewOptions = new PdfViewOptions("result.pdf");
    viewOptions.setImageMaxWidth(800);
    viewOptions.setImageMaxHeight(600);

    viewer.view(viewOptions);
}

In PdfViewOptions have following methods to set single image width/height in PDF.

/**
 * Max width of an output image in pixels. (When converting single image to HTML only)
 */
public int getImageMaxWidth();

/**
 * Max width of an output image in pixels. (When converting single image to HTML only)
 */
public void setImageMaxWidth(int imageMaxWidth);

/**
 * Max height of an output image in pixels. (When converting single image to HTML only)
 */
public int getImageMaxHeight();

/**
 * Max height of an output image in pixels. (When converting single image to HTML only)
 */
public void setImageMaxHeight(int imageMaxHeight);

/**
 * The width of the output image in pixels. (When converting single image to HTML only)
 */
public int getImageWidth();

/**
 * The width of the output image in pixels. (When converting single image to HTML only)
 */
public void setImageWidth(int imageWidth);

/**
 * The height of an output image in pixels. (When converting single image to HTML only)
 */
public int getImageHeight();

/**
 * The height of an output image in pixels. (When converting single image to HTML only)
 */
public void setImageHeight(int imageHeight);

Note: If you set Width/Height in options, MaxWidth/MaxHeight options will be ignored.
