This is a file about image that I found in phalcon. I looked at the source code and roughly understood how to implement it. The image.zep file defines an Image class, which defines some constants
as follows

Beginner to phalcon In the image folder, an abstract class Adapter is defined in adapter.zep, which defines some objects and many methods, including the following

public getImage () ... public getRealpath () ...
public getWidth () Image width public getHeight () Image
height public getType () Image type Driver dependent
public getMime () Image mime type
public resize ([unknown $width], [unknown $height],
[unknown $master] ) Resize the image to the given size
public liquidRescale (unknown $width, unknown $height,
[unknown $deltaX], [unknown $rigidity]) This method scales the images
using liquid rescaling method. Only support Imagick
public crop (unknown $width, unknown $height, [unknown $offsetX],
[unknown $offsetY]) Crop an image to the given size
public rotate (unknown $degrees) Rotate the image by a given
amount public flip (unknown $ direction) Flip the image along the
horizontal or vertical axis public sharpen (unknown $amount)
Sharpen the image by a given amount
public reflection (unknown $height, [unknown $opacity],
[unknown $fadeIn]) Add a reflection to an image
public watermark (unknown $watermark, [unknown $offsetX],
[unknown $offsetY], [unknown $opacity]) Add a watermark to an image
with the specified opacity public text (unknown $text,
[unknown $offsetX], [unknown $offsetY], [unknown $opacity],
[unknown $color], [unknown $size], [unknown $fontfile]) Add a text to
an image with a specified opacity public mask (unknown $watermark)
Composite one image onto another
public background (unknown $color, [unknown $opacity]) Set the
background color of an image public blur (unknown $radius) Blur
image public pixelate (unknown $amount) Pixelate image
public save ([unknown $file], [unknown $quality]) Save the image
public render ([unknown $ext], [unknown $quality]) Render the
image and return the binary string

Excerpted from Official documentation, not translated. . .

The AdapterInterface interface is defined in adapterinterface.zep, which declares many methods

In the adapter folder, there are two files that define two subclasses and many methods respectively.
