魔杖伪图像 - Python

Wand 支持许多图像格式规范，即一些使用 soem 算法创建的图像。伪图像非常重要，我们可以使用 wand 中的伪图像对图像进行各种操作。我们可以通过在Image()函数中设置伪参数来创建伪图像。

Some manipulations we can perform –

1. Create solid color image.
2. Create gradient images.
3. Create images with patterns
4. Creates a fractal image.

一些重要的伪图像：

Pseudo Image	Description
‘canvas:COLOR’, or ‘xc:COLOR’	Creates image with solid color, here COLOR is color value string
‘caption:TEXT’	Add text to image
‘gradient:START-END’	Generates a blended gradient between two colors, where both START and END are color value strings.
‘hald:’	Creates a Higher And Lower Dimension matrix table.
‘inline:VALUE’	where VALUE is a data-url / base64 string value..
‘label:TEXT’	where TEXT is a string message.
‘pattern:LABEL’	Generates image with a repeated pattern.
‘plasma:’	Generates a plasma fractal image
‘radial-gradient’	This is same as gradient but int this there is a circular blend of colors.
’tile:FILENAME’	Generates a repeating tile effect from a given images, where FILENAME is the path of a source image..

句法 ：

with Image(width=image_width, height=image_height,
                     pseudo='pseudo_type') as img:
    # other manipulation code
     

现在让我们继续研究伪图像的Python代码。

示例 1：创建带有渐变的图像

# Import Image from wand.image module
from wand.image import Image
  
# Create pseudo image using Image() function
with Image(width = 400, height = 300, 
        pseudo ='gradient:# 32a852-# 09e846') as img:
  
    # Save image with a validfilename
    img.save(filename ='gradient.png')

输出 ：

示例 2：创建带有图案的图像

# Import Image from wand.image module
from wand.image import Image
  
# Create image using Image() and label CROSSHATCH45 for pattern
with Image(width = 100, height = 100, pseudo ='pattern:CROSSHATCH45') as img:
  
    # Save image
    img.save(filename ='pattern.png')
