Hi Aspose Team,
We are currently evaluating Aspose for implementing document stamping functionality and would like to confirm if the library supports stamping on TIFF image files.
Specifically, we would like to know:
Does Aspose support adding text or image stamps on TIFF files?
Is stamping supported for both single-page and multi-page TIFF formats?
Can we position stamps (e.g., top-left, center, bottom-right) on each page of a multi-page TIFF?
Are there any limitations regarding color depth, compression type (e.g., LZW, CCITT), or file size when stamping TIFF images?
Which Aspose product or namespace should be used for this (e.g., Aspose.Imaging, Aspose.PDF, or Aspose.Words)?
If supported, could you please share a code snippet or example demonstrating how to stamp text or an image onto a TIFF file (both single and multi-page)?
Our use case involves processing TIFFs generated from scanned documents, and we need to apply stamps such as watermarks, approval labels, or timestamps on each page before saving the final file.
Thank you for your assistance.
Looking forward to your guidance and best practices for handling TIFF stamping using Aspose.
Best regards,
Ragu

Short answer
Yes – Aspose.Imaging can add both text and image stamps to TIFF files, whether the file has a single page or many pages. The same API works for all common TIFF compressions (LZW, CCITT Group 3/4, PackBits, JPEG, etc.) and lets you place the stamp anywhere you like.
Below is a clean, production‑ready C# example (the Java version uses the same classes in the com.aspose.imaging namespace).
1. Product / namespace
| Feature |
Aspose product |
Primary namespace |
| Image‑level stamping (text / image) on TIFF, PNG, JPEG, BMP, … |
Aspose.Imaging |
Aspose.Imaging – classes Image, TiffImage, ImageStamp, TiffOptions |
Aspose.PDF and Aspose.Words do not handle TIFF stamping.
2. What is supported?
| Item |
Support |
| Text stamp (Unicode, custom font, colour, opacity) |
 |
| Image stamp (PNG, JPEG, BMP, GIF – including transparent PNG) |
 |
| Single‑page TIFF |
 |
| Multi‑page TIFF (frames) |
– iterate the Frames collection |
Positioning – HorizontalAlignment / VerticalAlignment or explicit X / Y |
 |
| All standard TIFF compressions (LZW, CCITT Group 3/4, PackBits, Deflate, JPEG) |
 |
| Colour depths 1‑bit, 8‑bit, 24‑bit, 32‑bit, CMYK, etc. |
(conversion is automatic) |
| Very large TIFFs |
– load frames on‑demand with TiffLoadOptions.LoadAllFrames = false |
Edge cases
- 1‑bit (binary) TIFF – stamping forces a conversion to a higher‑bit format (e.g., 24‑bit). The library does this automatically; the file will no longer be 1‑bit.
- Huge multi‑page TIFFs – use on‑demand loading to keep memory usage low.
3. C# code example
using System;
using System.Drawing; // Font, Color
using Aspose.Imaging;
using Aspose.Imaging.FileFormats.Tiff;
using Aspose.Imaging.ImageOptions;
using Aspose.Imaging.LoadOptions; // TiffLoadOptions
class TiffStampDemo
{
static void Main()
{
const string inputPath = @"C:\Images\source.tif";
const string outputPath = @"C:\Images\stamped.tif";
// Load the TIFF without forcing all frames into memory (optional for huge files)
var loadOptions = new TiffLoadOptions { LoadAllFrames = false };
using (Image img = Image.Load(inputPath, loadOptions))
{
// Cast to TiffImage to work with frames
var tiff = (TiffImage)img;
// ---------- Text stamp ----------
var textStamp = new ImageStamp
{
Text = "APPROVED",
Font = new Font("Arial", 36),
TextColor = Color.Red,
Opacity = 0.5f, // 0 = fully transparent, 1 = opaque
HorizontalAlignment = HorizontalAlignment.Center,
VerticalAlignment = VerticalAlignment.Center
// X = 10, Y = 10 // use for exact coordinates instead of alignment
};
// ---------- (Optional) Image stamp ----------
// var logo = Image.Load(@"C:\Images\logo.png");
// var imageStamp = new ImageStamp
// {
// Image = logo,
// Opacity = 0.7f,
// X = 20,
// Y = 20
// };
// Apply the stamp to every frame (page) of the TIFF
foreach (var frame in tiff.Frames)
{
frame.AddStamp(textStamp);
// frame.AddStamp(imageStamp); // uncomment if you need an image stamp
}
// ---------- Save ----------
var saveOptions = new TiffOptions(TiffExpectedFormat.Default);
// Keep the original compression (optional)
// saveOptions.Compression = ((TiffFrame)tiff.Frames[0]).Compression;
tiff.Save(outputPath, saveOptions);
}
Console.WriteLine("Stamping completed.");
}
}
How the snippet works
| Step |
What it does |
Image.Load(..., TiffLoadOptions) |
Reads the TIFF; LoadAllFrames = false keeps memory low for huge files. |
Cast to TiffImage |
Gives access to the Frames collection (one frame = one page). |
Create ImageStamp |
Configures either a text stamp (Text, Font, TextColor) or an image stamp (Image). |
frame.AddStamp(...) |
Adds the stamp to the current page. |
TiffOptions |
Allows you to preserve the original compression or choose a new one. |
tiff.Save(...) |
Writes the stamped TIFF back to disk. |
For a single‑page TIFF you can skip the foreach loop and call tiff.AddStamp(textStamp) directly.
4. Best‑practice tips
| Situation |
Recommendation |
| Very large multi‑page TIFF (hundreds of MB or thousands of pages) |
Use TiffLoadOptions.LoadAllFrames = false and process frames one‑by‑one. |
| Preserve original compression |
Read ((TiffFrame)frame).Compression from the first frame and assign it to TiffOptions.Compression before saving. |
| Transparent PNG stamp |
Use a PNG with an alpha channel; control overall transparency with Opacity. |
| Batch processing |
Wrap the stamping logic in a method that receives input path, output path, stamp definition, and an optional list of page indexes to stamp. |
| Memory pressure |
Dispose of any temporary images (e.g., a logo) as soon as they are no longer needed (logo.Dispose()). |
5. Limitations / gotchas
| Limitation |
Details |
| Binary (1‑bit) TIFF |
After stamping the image is automatically converted to a higher‑bit format (usually 24‑bit). |
| CCITT‑compressed TIFF |
Supported for read/write. Stamping rasterises the image, then re‑encodes it with the same CCITT compression if you keep TiffOptions.Compression set accordingly. |
| File‑size limit |
No hard limit in the library; only the host process memory. Use on‑demand loading for extremely large files. |
| ICC profile |
Preserved automatically; stamping does not alter it. |
6. Quick FAQ
| Question |
Answer |
| Do I need a separate license for TIFF stamping? |
No. A license for Aspose.Imaging covers all image formats, including TIFF. |
| Can I stamp only selected pages of a multi‑page TIFF? |
Yes. Iterate tiff.Frames and call AddStamp only on the frames whose indexes you want to modify. |
| Is there a Java version? |
Absolutely. The same classes exist in com.aspose.imaging (Image, TiffImage, ImageStamp, TiffOptions). Replace C# syntax with Java equivalents. |
| What if I first convert a PDF to TIFF? |
Use Aspose.PDF (PdfConverter) to create the TIFF, then apply the same Aspose.Imaging stamping code. |
TL;DR
Use Aspose.Imaging (ImageStamp + TiffImage) to add text or image stamps to any TIFF—single‑ or multi‑page, any compression. The example above shows a clean, production‑ready workflow that works for large files and lets you control placement, opacity, and output compression.
