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,
