Adding watermarks in Telegram

FLOWIN lets you set up automatic watermarks for forwarded images, videos, PDF documents, and even audio files.

Watermark capabilities

A watermark can be text, an image, or an audio clip. Watermarks have many settings, including size, visibility, offset, and position.

In FLOWIN, a new message arrives at the destination with the watermark already added. There is no need to publish the message first and then edit or delete it. A text watermark can include information that changes, such as the message date and time.

FLOWIN lets you set up several watermarks: use them for different channels or apply them to the same original media file. The option to add watermarks to text messages lets you attach your own images or audio to forwarded messages without media.

Once set up, new messages with the selected media types will be forwarded from the source to your chat or channel with watermarks.

Text watermarks

Watermarks in FLOWIN let you add any text to forwarded videos, images, or PDF documents.

Creating a text watermark

For example, a pottery studio posts photos of its work in a channel. Let’s add the name “Pottery Studio” so that it stays on the photos when they are forwarded again.

0. Open @flow_in_bot, send the /start command, and click “Control panel”.

   

1. Open “Menu” → “Watermarks” → “Inserting text” and click “Create”.

   

   

2. In the “Text” field, enter Pottery Studio. To make the text stand out on the photo, set “Size” to 40px and click “Create”.

   

   

3. Click “Apply” next to the watermark you created. Select the forward for the studio’s photos and click “Save”.

   

   

4. “Forwards [1]” will appear in the watermark’s row. New photos in the selected forward will arrive with “Pottery Studio” on them.

   

   

   

How to edit a watermark

Let’s look at the text watermark settings using the watermark we created.

1. Click “Change” with the pencil icon in the watermark’s row. Its settings dialog will open.

   

2. Change the settings you need. For example, enter Studio name on photos in “Description” and click “Save”. The description will appear in the watermark’s row.

   

   

Text watermark settings

Text

The watermark content added to forwarded media files.

You can use metatags in this field.

Where

The watermark’s position on the media:

• “Left Top”, “Right Top”, “Left Bottom”, “Right Bottom”: one of the four corners.
• “Center”: the center of the image.
• “Repeat”: the watermark is repeated across the image.
• “Random”: the position is chosen randomly.

Color

The text color. Click the colored circle next to the “Where” field and choose a color.

Size

The text size in pixels, from 8 to 128.

Visibility

The text’s visibility, from 1% to 100%. The lower the value, the more transparent the watermark.

Offset

The offset from the selected position, in pixels. A negative value adds margins to the original image, where the watermark is placed. A negative offset applies only to images and PDF documents.

Optimize quality

Reduces the resulting media file’s size and speeds up processing at the cost of a slight reduction in quality.

Media types

• “Add to images” enables the watermark on forwarded images.
• “Add to pdf” enables the watermark on forwarded PDF documents.
• “Add to videos” enables the watermark on forwarded videos.

Description

An optional comment for your convenience. It does not affect how the watermark works.

Metadata in a text watermark

You can use special metatags in the watermark text to add message information. The main metatags are:

• message date: <message-date>
• message time: <message-time>
• author ID: <author-id>
• author name: <author-name>
• author name as a link: <author-name-link>
• author name as a tag: <author-name-tag>
• author username: <author-username>
• message text in the source: <src-message-text>
• message ID in the source: <src-message-id>
• message link in the source: <src-message-link>
• source chat ID: <src-chat-id>
• source chat name: <src-chat-name>
• source chat username: <src-chat-username>
• source topic ID: <src-topic-id>
• source topic name: <src-topic-name>
• message text at the destination: <dst-message-text>
• destination chat ID: <dst-chat-id>
• destination chat name: <dst-chat-name>
• destination chat username: <dst-chat-username>
• destination topic ID: <dst-topic-id>
• destination topic name: <dst-topic-name>
• regular expression: <regexp>(short|sell)</regexp>
• random text: <random>1|2|3|4|5</random>

Below the “Text” field, the “metatags” tooltip has the current list. For example, Pottery Studio · <message-date> adds the original message’s date to the name. A link or author name on the image itself will be part of the watermark text; it cannot be clicked as a link.

Image watermarks

FLOWIN lets you use a PNG or JPEG image as a watermark.

Creating an image watermark

For example, let’s add the studio’s image mark to the photos instead of its name. Use the forward you prepared in “Copy” mode.

1. Open “Menu” → “Watermarks” → “Inserting image” and click “Create”.

   

   

2. Click “Upload watermark” and select the image you prepared. To make the studio’s mark clearly visible, set “Size” to 30% and click “Create”.

   

   

   

3. Click “Apply” next to the new watermark and select a forward, as you did for the text watermark.

   

4. A linked forward will appear next to the watermark. New photos will arrive with the selected image on them.

   

   

   

Image watermark settings

Let’s look at the settings of the image watermark we created. To edit it, click “Change” next to it.

Save changes with the “Save” button, as in the editing instructions.

Image

The image added to forwarded media files. Click it to choose another one.

Where

The watermark’s position on the media. The same seven position options are available as for a text watermark.

Size

The image size relative to the original media, from 5% to 100%.

Offset

The offset from the selected position, in pixels. A negative value adds margins for the watermark only to images and PDF documents.

Optimize quality

Reduces the file size and speeds up processing at the cost of a slight reduction in quality, as with a text watermark.

Which messages to add it to

• “Add to text messages” attaches the selected image to forwarded messages without other media.
• “Add to images” overlays the watermark on forwarded images.
• “Add to pdf” overlays the watermark on forwarded PDF documents.
• “Add to videos” overlays the watermark on forwarded videos.

Audio watermarks

FLOWIN lets you use an audio clip as a watermark: it is automatically added to forwarded voice messages or audio files.

Creating an audio watermark

For example, let’s add a short “Pottery Studio” intro at the beginning of each audio lesson. Prepare the intro in MP3 or OGG format and set up a forward in “Copy” mode for the lessons.

1. Open “Menu” → “Watermarks” → “Inserting audio” and click “Create”.

   

   

2. Click “Upload watermark”, select the audio intro, and click “Create”.

   

   

3. Click “Apply” next to the new watermark and select the forward for the audio lessons.

   

4. A linked forward will appear next to the watermark. The selected intro will play at the beginning of new forwarded audio lessons.

   

   

   

Audio watermark settings

Let’s look at the settings of the audio watermark we created. To edit it, click “Change” next to it.

After making changes, click “Save”.

Audio

The audio clip added to forwarded audio files. Click it to choose another one.

Where

Where the clip is inserted into the original audio:

• “Start”: before the original recording.
• “End”: after the original recording.
• “Random”: at a random point.

Volume

The volume of your audio clip, from 5% to 500%.

Insert as Background

Overlays your clip on the original audio as background audio.

Which messages to add it to

• “Add to text messages” attaches the selected audio to forwarded messages without other media.
• “Add to audio” enables insertion of the clip into forwarded audio recordings.

Removing watermarks from images

FLOWIN lets you not only add watermarks but also automatically make them less visible on forwarded images. The feature changes the image’s contrast, brightness, and saturation, so a semi-transparent watermark may become invisible.

Setting up watermark removal from images

Let’s test the setting on our own light image with faint text. Use a separate forward in “Copy” mode to adjust the settings before processing other images.

1. Open “Menu” → “Watermarks” → “Removing from images” and click “Create”. Confirm by clicking “Create” in the dialog that opens.

   

   

   

2. Click “Apply” and select the forward you prepared.

   

3. Compare the original and forwarded images. FLOWIN will apply the selected contrast, brightness, and saturation. In this example, the faint watermark on the light background will become less visible.

   

   

   

How to adjust removal settings

The form has “Contrast”, “Brightness”, “Saturation”, and an optional “Description”. If you are not satisfied with the result, try different values.

1. To adjust watermark removal, click “Change” in its row, change the settings, and click “Save”.

   

   

2. Compare the next forwarded image with the original, as in the example above. Changing the settings will affect new processing results.

Available watermark actions

The “Change” button with the pencil icon opens the watermark’s main settings. Other actions are available in the “More” menu:

• “Apply”: select forwards for this watermark.
• “Duplicate”: create a copy of the watermark with the same settings.
• “Select project”: add the watermark to a project.
• “Delete”: delete the watermark.

The “Forwards [number]” button shows the number of linked forwards. Click it to change the selection, then click “Save”.
