Generally Add Watermark needs following permissions to be granted on your device:
WRITE_EXTERNAL_STORAGE: Allows an application to read from and write to device or external storage.
WAKE_LOCK: Allows to keep device from sleeping during processing of multiple images.
Beginning in Android 6.0, users grant permissions to apps while the app is running, not when they install the app.
When you start the app for the first time, you should see a permission request dialog:
Once allowed it doesn’t appear any more. But when you for some reason don’t allow, the app will generate errors when trying to load a source image or save processed image. In this case just restart the app, it will show the permission request again. Press “Allow” and that’s it!
Sometimes the permission request doesn’t appear, instead you see a “Screen overlay detected” message. This is because of another app with a floating overlay like Facebook Messenger, Twilight, CleanMaster, or Lux, that blocks permission requests from other apps. In this case please try to close all such floating activities then launch Add Watermark again. It is supposed to request permission without the “Screen overlay detected” error popping up.
Since version V3.0 there is full support of EXIF and XMP metadata in Jpeg images. That means, all metadata saved in the original image like photosphere tags, specific copter data, is also present in processed pictures.
For example, you can watermark a photosphere (360° panorama) to produce awesome 3D text effects. Viewing or posting processed pictures e.g. to Facebook works the same way like with original images. Make your spherical panoramas to eye-catcher!
How Facebook does determine whether a photo is in 360: – The photo must have a 2:1 aspect ratio, with maximum file dimensions of 6000 x 3000 pixels – The Exif XMP tag “ProjectionType=equirectangular” Learn more: Editing 360 Photos & Injecting Metadata
In the new version V3.0 we could fix an old aliasing problem, where a logo gets pixelased and can look ugly on the resulting image. This happened sometimes when the watermark image was rotated and downscaled too much.
Now the logo looks fine due to using of antialiasing filter while processing. Here you can see the difference before/after:
You don’t need to change or set anything in the settings. It works fully automatically.
Since the new version 3.0 you can easy recall up to 20 recently used watermarks with all their properties. Like using profiles to quick switch between many predefined settings. How this works:
Each time you save resulting image the app stores all watermark settings in the list “Recent texts” or “Recent images” depending on the current watermark type.
To reuse one of last used watermarks please follow the steps:
Open Settings (pressing edit or gear button)
Go to Text or Image settings depending on your need
Press button “Recent texts” or “Recent images”
Choose an entry from the list
You can see immediately the loaded settings
Close Settings (pressing the back button) to see how the watermark looks on the preview
Now you can save the resulting image
Please don’t forget: as a confirmation you need to save your resulting image to make sure your new/changed watermark’s properties can be recalled from the recent list.
If you apply changes to a recent watermark, they will be updated while saving resulting image until you change the watermark content itself (text or watermark file name). Then it will be saved under a new name.
After a new installation the list “Recent texts” already contains a preloaded set of watermark samples. Try them out!
The earlier watermarks (>20) will be replaced with last ones. Last saved comes always up in the list.
List of “Recent images” saves both types of image watermarks: built-in stickers and user’s custom logos.
When you are storing your images in Dropbox cloud, you may be wondering, how to watermark more than one image using batch mode. Because currently in Dropbox you can select only one single file to send it to another app.
Please find below a workaround. To say it short, you need first to download images to device.
1. Start Dropbox and mark needed images, then save them to device (use three point menu > save to device):
2. When they are saved (you can see the status on icons), open Add Watermark, select source (+) > process multiple images
3. Navigate to the Dropbox folder – it looks similar to /sdcard/Android/data/com.dropbox.and.android/files/XXXXXXX/scratch…,
select all images, then process them.
I don’t recommend to process more than 100 images at once, as it can take very long time (few minutes).
Problem: You have a Samsung Galaxy S4, S5 or Note3 with the newest Android 4.4.2 KitKat. When you try to save a watermarked image the following error is occurred: “X images were not processed due to errors…”
This is a known issue and it seems to be unique to the Android 4.4.2 KitKat update for the Galaxy S4 and Note 3 only. The new specifications in the Android API pretty much makes your microSD card useless. The third party apps will not be allowed to use it. More about here: http://goo.gl/xtPOye.
So, for example, you want to watermark some pictures taken with the standard camera app, stored on the microSD card. By default in Add Watermark the target folder is set to “Default folder”. This is the folder where the source images are stored. And this causes the problem. As applications are no longer able to create, modify, or remove files and folders on the external SD card due to new Android security policies.
You need to use the internal storage for saving images in Add Watermark. Please set the target folder in the save dialog to “Custom folder” and choose a place, for example “/storage/emulated/0/addwatermark”.
If you share your watermarked pictures via Instagram app, you might be wondering, why posted pictures on Instagram looks so pixelated and blurred. The pictures before posting does look pretty good, so it seems to be a problem of Instagram app or server.
That can be fixed in Instagram app’s settings:
Just go to your profile page, open “Options” (three dots on the top right), then go to “Settings” / “Camera“, disable “Use High-Quality Image Processing” as showed below:
By the way, if you are using the free version of Add Watermark:
The sharing is much easier in the full version. Simply check the option “Share after saving” in the Save dialogue.
