webpmux

Add ICC profile,XMP metadata and EXIF metadata

from webptools import webpmux_add

# pass input_image(.webp image) path,output_image,set options(icc image profile,XMP metadata or EXIF metadata) and file.
# for options use keywords as below
# for ICC: icc
# for XMP metadata: xmp
# for EXIF metadata: exif
print(webpmux_add(input_image="in.webp", output_image="icc_container.webp",
                  icc_profile="image_profile.icc", option="icc"))

Extract ICC profile,XMP metadata and EXIF metadata

from webptools import webpmux_extract

# pass input_image(.webp image) path,output_image,set options(icc image profile,XMP metadata or EXIF metadata) and file.
# for options use keywords as below
# for ICC: icc
# for XMP metadata: xmp
# for EXIF metadata: exif
print(webpmux_extract(input_image="anim_container.webp",

print(webpmux_strip(input_image="icc_container.webp",
                    output_image="without_icc.webp", option="icc"))

Create an animated WebP file from Webp images

from webptools import webpmux_animate

# pass input_images(.webp image) path with FRAME_OPTIONS, as array,ouput image will be animated .webp image

# https://developers.google.com/speed/webp/docs/webpmux
# FRAME_OPTIONS

# -file_i +di[+xi+yi[+mi[bi]]]

# e.g -frame one.webp +100 -frame two.webp +100+50+50 -frame three.webp +100+50+50+1+b

# Where: file_i is the i'th frame (WebP format), xi,yi specify the image offset for this frame,
# di is the pause duration before next frame, mi is the dispose method for this frame (0 for NONE or 1 for BACKGROUND)
# and bi is the blending method for this frame (+b for BLEND or -b for NO_BLEND).
# Argument bi can be omitted and will default to +b (BLEND). Also, mi can be omitted if bi is omitted and
# will default to 0 (NONE). Finally,
# if mi and bi are omitted then xi and yi can be omitted and will default to +0+0.

# -loop n

# e.g 10

# Loop the frames n number of times. 0 indicates the frames should loop forever.
# Valid range is 0 to 65535 [Default: 0 (infinite)].

# -bgcolor A,R,G,B

# e.g 255,255,255,255

# Background color of the canvas. Where: A, R, G and B are integers in the range 0 to 255 specifying
# the Alpha, Red, Green and Blue component values respectively [Default: 255,255,255,255].

input = ["./frames/tmp-0.webp +100", "./frames/tmp-1.webp +100",
         "./frames/tmp-2.webp +100"]
print(webpmux_animate(input_images=input, output_image="anim_container.webp",
                      loop="10", bgcolor="255,255,255,255"))

Get a frame from an animated WebP file

from webptools import webpmux_getframe

# pass input_image(.webp image) path ,output_image and frame number
print(webpmux_getframe(input_image="anim_container.webp",
                       output_image="frame_2.webp", frame_number="2"))
