How to set alt text on image using figure caption? #245
Description
Hello,
How to use the figure caption text from the source Ms Word document as alt text on the generated tag?
In the source document.xml I see the following:
<w:drawing>
<wp:inline distT="0" distB="0" distL="0" distR="0">
<wp:extent cx="5943600" cy="8210550"/>
<wp:effectExtent l="0" t="0" r="0" b="0"/>
<wp:docPr id="16" name="Picture 16"
descr="Image description."
title="Image description"/>
<wp:cNvGraphicFramePr>
.......
I need to grab the value of the descr="Image description" or title="Image description" from the above excerpt of the source document.xml
I am currently using below custom image export function, which allows me to save my images to a local folder:
[]( def get_image_tag(self, image, width=None, height=None, rotate=None):
# unique_filename = str(uuid.uuid4())
img_src = self.get_image_source(image)
if img_src:
# Getting images from the source
attrs = {
'src': img_src
}
# get base64 file extension from bytes
# https://matthewdaly.co.uk/blog/2015/07/04/handling-images-as-base64-strings-with-django-rest-framework/
format, img_src2 = img_src.split(';base64,') # format ~= data:image/X,
ext = format.split('/')[-1] # guess file extension
# Capture the generated filename with the proper extension to use in img source attribute
img_src_new = 'img_' + image_name() + '.' + ext
# Function to convert base64 string to image using urlretireve
urlretrieve(img_src, 'c:/git/output/' + img_src_new)
# Set the image source to the newly created filename
attrs = {
'src': img_src_new
}
if width and height:
attrs['width'] = width
attrs['height'] = height
if rotate:
attrs['style'] = 'transform: rotate(%sdeg);' % rotate
return HtmlTag('img', allow_self_closing=True, allow_whitespace=True, **attrs))
Thanks for your help.
