applications – Software to generate and display OLED burn-in offset map as watermark over display?

Have a Galaxy S8+ with signs of burn-in – not serious but white screens are looking a little pink in regions.
Searching for fixes to burn-in only comes up with programs to flex the pixels which I don’t believe can do anything. What I would like to find if it exists is a way to display a semi-transparent watermark over the entire screen in order to boost the blue and green pixels in the burnt regions to even out the display – the image could be either traced by user on the effected screen, or generated from a photo taken by a second camera..

Is there either an existing app on the market to do this or a way of doing it by hand with some type of hackery?

What do I change in this Python script to stop the resizing of an image when adding a watermark

I have this script which is successfully applying a watermark to an image, resizing the watermark and setting the image “quality”.
I find that it’s actually reducing the quality and resizing it to be smaller than I want.

This is a telegram bot that I’m using, I send the image to the bot, the bot is adding the watermark and then resizing. I don’t want the resizing part at all. I want the original size + the watermark.

QUESTION: How do i change this so it doesn’t resize my original image that the watermark is added to?


  1. I sent image to my bot which activates the script
  2. The script adds a watermark and resizes the image
  3. The script sends the resized image back to me with the watermark included


  1. I send image to my bot which activates script
  2. The script adds a watermark but does not resize the original image
  3. The script sends the image back to me with the watermark included

c++ – Simplifying small watermark application

I recently started out with C++ and I am working on an application that can watermark entire directories of images at once.

Currently you can call the program with an argument of the target directory where the images are stored and an argument for the path of which watermark image to use.

It works so far but I think my code is a bit messy. I don’t really know how to make it more readable and more clean, so I am asking for your help.

I would really appreciate it if people could look at my code and review it. All feedback is welcome.

macos – Add page numbers using print dialog box’s “watermark” tool

In most applications, such as preview, the print dialog box has a watermark feature. It is possible to open a PDF document and watermark it e.g. bottom right with a text and print it again back in to a new PDF.
print dialog box
Is it possible / is there a hidden feature that allows inserting page numbers / total number of pages in the watermark field, where it is automatically replaced by corresponding numbers at the time of printing?

licensing – Is using image found on google (without watermark) and turning it into pixel art with some filter would be illegal?

I’m working on AI collage generator with multiple png images from the internet (using google images search) and I wonder would my program break the law or not.
Program checks for watermark and omits images with watermarks.
The images will be pixelified like very much, even PNG image of a flower 1024×768 will be transformed into 16×16 pixelified image.

It’s like you type “barn with a sun and a horse on a field nearby” will create image with taken images from over the internet, but it will be like pixel art.

Generated images can be used by anyone, no matter the purpose.

plugins – How to add watermark to wordpress media images and then sending them to remote cdn

I’m using wordpress Image Watermark plugin to add watermark to images when uploading. then for moving theme to cdn, i use Hacklog Remote Attachment plugin to move my media images from wordpress upload directory with FTP. but the problem is watermark doesn’t apply when using this FTP plugin. I try coding my own FTP connection with php using wp_get_attachment_metadata filter but it moves images right after uploading to cdn and because of this, watermark does not apply. Does anyone have any way to do this with coding or plugin?

magento2 – Watermark issue – Magento Stack Exchange

Currently we are running on Magento 2.2.6.
We have added a watermark for the base, thumbnail, swatch & small.

The watermark is appearing on the productlist page, but not in a good manner, see image.

But the worse thing is, it isn’t even showing on the productdetail page. Yes I see the image but not a watermark. Herefore i’m searching a solution. The first issue will be related to this older version of magento we are running.

enter image description here

Hopefully anyone has some experience for this topic and thanks for the help.



Watermark text-on-text repeated diagonally css/html (and possibly javascript)

How does one achieve a text-on-text watermark in HMTL and CSS? If adding javascript makes it cleaner, that is acceptable. I’m OK with writing HTML and simple CSS, but this would be my first foray into javascript.

The answers to this earlier question seemed to assume that the foreground was a single “img”. But my question is for when the foreground is multi-paragraph text.

The foreground text could be quite large, say, 100 lines in several paragraphs.

The short background text, typically one word “Draft”, and preferably diagonally, as in that earlier question, should be specified just once and repeated arbitrarily.

Showing how to implement that earlier question’s posed illustration using two “p” paragraphs for the foreground “Text Watermark” and “For Blogger” would be ideal (no need to worry here about the formatting within those paragraphs). Or take this question itself and put a repeated diagonal background text “Draft” behind it.
