How to save ALL document pages into one PNG file?

[FabioAntunes]

Hello, im trying to save a document (com.aspose.words.Document) into a png file, but for example for a template with 4 pages, the generated png have 4 document's first page instead of 4 different files.

The code im using is:

final ByteArrayOutputStream out = new ByteArrayOutputStream();

List images = new ArrayList();

int bigImageWidth = 0;

int bigImageHeight = 0;

ImageSaveOptions options = new ImageSaveOptions(SaveFormat.PNG);

options.setPageCount(1);

ByteArrayOutputStream imgStream = new ByteArrayOutputStream();

for (int i = 0; i < doc.getPageCount(); i++){

options.setPageIndex(i);

doc.save(imgStream, options);

ByteArrayInputStream imgInputStream = new ByteArrayInputStream(imgStream.toByteArray());

BufferedImage read = ImageIO.read(imgInputStream);

images.add(read);

bigImageWidth = (bigImageWidth < read.getWidth()) ? read.getWidth() : bigImageWidth;

bigImageHeight += read.getHeight();

imgInputStream.close();

}

imgStream.close();

BufferedImage finalImage = new BufferedImage(bigImageWidth, bigImageHeight, BufferedImage.TYPE_INT_RGB);

Graphics2D g2d = finalImage.createGraphics();

int x = 0;

int y = 0;

for (BufferedImage bufferedImage : images) {

g2d.drawImage(bufferedImage, null, x, y);

y += bufferedImage.getHeight();

}

ImageIO.write(finalImage, format, out);

am i missing something ? Could you please provide some help ?

Kind Regards,

Hi Fábio,

Thanks for your inquiry. Please use the following Java code to save all pages in Word document to a single big PNG image file:

Document doc = new Document(getMyDir() + “input.docx”);
List<BufferedImage> images = new ArrayList<BufferedImage>();
int bigImageWidth = 0;

int bigImageHeight = 0;
ImageSaveOptions options = new ImageSaveOptions(SaveFormat.PNG);

options.setPageCount(1);
for (int i = 0; i < doc.getPageCount(); i++){

options.setPageIndex(i);

}
BufferedImage finalImage = new BufferedImage(bigImageWidth, bigImageHeight, BufferedImage.TYPE_INT_RGB);

Graphics2D g2d = finalImage.createGraphics();

int x = 0;

int y = 0;
for (BufferedImage bufferedImage : images) {

g2d.drawImage(bufferedImage, null, x, y);

y += bufferedImage.getHeight();

}
ImageIO.write(finalImage, “PNG”, new File(“D:\Temp\out.png”));

I hope, this helps.

Best regards,
