Imagesequence module Introduction to Python image processing library pil

imagesequence The module includes a wrapper class that allows users to iterate through each frame of an image in a sequence of graphics.

function of the imagesequence Module

1. Iterator

Definition:imagesequence.iterator (image)? Iterator Instance

Meaning: Create an iterator instance that allows the user to iterate through all the frame images in the sequence.

Examples: see below for examples.

Second, the method of Imagesequence module

1. Operator

Definition: Operator []

Meaning: The user invokes the operator, starting from 0 .

When there is no other frame image. This iterator will produce a indexerror exception.

Examples:

From PIL import image, Imagesequenceim = Image.open ("d:\\code\\python\\test\\img\\test01.gif") index = 1for frame in Image Sequence.iterator (IM):    print "Image:index%d, mode%s, size%s"% (index, Frame.mode, frame.size)    Frame.save ("fr Ame%d.png "% index"    index = index + 1iter = Imagesequence.iterator (IM) print "Image 10:mode%s, size%s"% (iter[10].m Ode, Iter[10].size) Iter[10].show ()

The image is test01.gif as multiple dynamic images.

An iterator to the im of the image object is obtained through the function imagesequence.iterator (IM) , and each picture is taken out of one sheet. Their patterns and dimensions are printed. The corresponding image in the iterator is obtained later by the operator [] . iter[10] corresponds to the tenth image.

The program outputs such as the following:

Image:index 1, Mode P, size (450, 450)

Image:index 2, Mode P, size (450, 450)

Image:index 3, Mode P, size (450, 450)

Image:index 4, Mode P, size (450, 450)

Image:index 5, Mode P, size (450, 450)

Image:index 6, Mode P, size (450, 450)

Image:index 7, Mode P, size (450, 450)

Image:index 8, Mode P, size (450, 450)

Image:index 9, Mode P, size (450, 450)

Image:index, Mode P, size (450, 450)

Image:index, Mode P, size (450, 450)

Image:index, Mode P, size (450, 450)

Image:index, Mode P, size (450, 450)

Image:index, Mode P, size (450, 450)

Image:index, Mode P, size (450, 450)

Image:index, Mode P, size (450, 450)

Image:index, Mode P, size (450, 450)

Image:index, Mode P, size (450, 450)

Image:index, Mode P, size (450, 450)

Image:index, Mode P, size (450, 450)

Image:index, Mode P, size (450, 450)

Image:index, Mode P, size (450, 450)

Image:index, Mode P, size (450, 450)

Image10:mode P, size (450, 450)

Image Test01.gif such as the following:

The second image is:

Watermark/2/text/ahr0cdovl2jsb2cuy3nkbi5uzxqv/font/5a6l5l2t/fontsize/400/fill/i0jbqkfcma==/dissolve/70/gravity /center ">

The 20th image is:

Watermark/2/text/ahr0cdovl2jsb2cuy3nkbi5uzxqv/font/5a6l5l2t/fontsize/400/fill/i0jbqkfcma==/dissolve/70/gravity /center ">

The tenth image obtained by the operator [] is followed by the following example:
