Image Watermark:

The ImageWatermark node is designed to seamlessly integrate watermarks into images, providing a robust solution for protecting and branding your digital artwork. This node allows you to overlay text-based watermarks onto images, ensuring that your creative works are safeguarded against unauthorized use. By offering customizable options such as text content, font style, color, opacity, and positioning, the node empowers you to create watermarks that are both aesthetically pleasing and effective in conveying ownership. The ImageWatermark node is particularly beneficial for artists and designers who wish to maintain the integrity of their work while sharing it online, as it provides a straightforward method to apply consistent and professional watermarks across multiple images.

Image Watermark Input Parameters:

images

This parameter accepts the images to which the watermark will be applied. It is crucial as it determines the base on which the watermark will be overlaid. The images should be in a compatible format for processing.

text

This parameter specifies the text content of the watermark. It is the actual string that will appear on the image, serving as the primary identifier or message of the watermark.

font_file

This parameter defines the font style used for the watermark text. It allows you to choose a specific font file to ensure the text appears in the desired style, enhancing the visual appeal of the watermark.

angle

This parameter sets the rotation angle of the watermark text. By default, it is set to 30 degrees, allowing for diagonal placement, which can be adjusted to suit your design preferences.

red, green, blue

These parameters control the color of the watermark text by specifying the RGB color values. Each value ranges from 0 to 255, allowing you to customize the text color to match or contrast with the image.

opacity

This parameter determines the transparency level of the watermark, with a default value of 0.15. It ranges from 0 (completely transparent) to 1 (completely opaque), allowing you to adjust the visibility of the watermark.

size

This parameter specifies the font size of the watermark text, with a default value of 50. It allows you to control the prominence of the watermark on the image.

space

This parameter sets the spacing between repeated instances of the watermark text, with a default value of 75. It helps in creating a pattern or grid of watermarks across the image.

movement_type

This parameter allows you to choose the type of movement for the watermark, with options like "None", "up_down", "left_right", and "angel_change". It adds dynamic effects to the watermark placement.

movement_amount

This parameter defines the extent of movement for the watermark when a movement type is selected. It ranges from 0.2 to 5, with a default of 1, allowing for subtle or pronounced movement effects.

chars_per_line

This parameter sets the number of characters per line in the watermark text, with a default value of 8. It helps in formatting the text to fit within the desired space on the image.

font_height_crop

This parameter adjusts the height of the font, with a default value of 1.2. It allows for fine-tuning the vertical space occupied by the text, ensuring it fits well within the image.

Image Watermark Output Parameters:

images

The output is a tensor representing the watermarked images. This tensor contains the processed images with the applied watermark, ready for further use or distribution. The output ensures that your images are protected with a consistent and professional watermark.

Image Watermark Usage Tips:

• To achieve a subtle watermark effect, adjust the opacity parameter to a lower value, ensuring the watermark is visible but not overpowering the image.
• Experiment with different font_file and angle settings to create unique and visually appealing watermark designs that complement your artwork.
