I am following this link for adding background image to excel
<pre style=“background-color: rgb(255, 255, 255); font-family: “Fira Code”; font-size: 9pt;”>ClassLoader classLoader = getClass().getClassLoader();
File file = new File(classLoader.getResource(“base.png”).getFile());
byte[] imageData = new byte[(int) file.length()];
FileInputStream fis = new FileInputStream(file);
fis.read(imageData);
for (int i = 0; i < workbook.getWorksheets().getCount(); i++) {
Worksheet worksheet = workbook.getWorksheets().get(i);
worksheet.setBackgroundImage(imageData);
}<pre style=“background-color: rgb(255, 255, 255); font-family: “Fira Code”; font-size: 9pt;”>
<pre style=“background-color: rgb(255, 255, 255); font-family: “Fira Code”; font-size: 9pt;”>The above code is applying background image to excel file, but the size of excel file<pre style=“background-color: rgb(255, 255, 255); font-family: “Fira Code”; font-size: 9pt;”>is becoming very large in MB (10 to 20MB).<pre style=“background-color: rgb(255, 255, 255); font-family: “Fira Code”; font-size: 9pt;”>I am not able to figure out this behavior, please inform me if there is any solution.
