¶ ObjTextDataimage
The ObjTextDataimage object is a utility for embedding an image directly into an HTML <img> tag using a data URI. This is useful for displaying images that are generated on the fly or stored in a database, as it avoids the need to save the image as a file.
The object constructs the <img> tag with the source (src) attribute populated with the Base64-encoded image data.
¶ Methods
¶ Process(Param1: str, Param2: str, Param3: str, Param4: str, ...)
This method takes the necessary components of a data URI and constructs the complete <img> tag.
Parameters:
Param1(str): The MIME type of the image (e.g.,image/png,image/jpeg,image/svg+xml).Param2(str): The Base64-encoded string of the image data.Param3(str, optional): The alternative text (alt) for the image. Defaults to "Embedded Image".Param4(str, optional): The CSS class to apply to the image. Defaults toimg-fluid.
Returns:
- (str): A string containing the complete HTML
<img>tag with the embedded image.
Example Usage:
# A simple 1x1 red pixel PNG, Base64 encoded
base64_red_pixel = "iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAQAAAC1HAwCAAAAC0lEQVR42mP8/wcAAwAB/epv2AAAAABJRU5ErkJggg=="
image_generator = ObjProcessText()
image_html = image_generator.Process(
Param1="image/png",
Param2=base64_red_pixel,
Param3="A single red pixel",
Param4="img-thumbnail"
)
print(image_html)
This would output:
<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAQAAAC1HAwCAAAAC0lEQVR42mP8/wcAAwAB/epv2AAAAABJRU5ErkJggg==" class="img-thumbnail" alt="A single red pixel">
