Config Fill Modes · PAG官网

Usage Scenarios

The PAG fill mode is mainly used in the following two scenarios:

When the rendered size (PAGView, PAGSurface size) is inconsistent with the size of the pag file
When the size of the placeholder image n the pag file is inconsistent with the size of the filled image

The Effect of Fill Mode

PAG supports the following fill modes:

None: No scaling. Cropping starts at the upper left corner.
LetterBox: Black edge. Scaling to the available screen size of the device while maintaining aspect ratio ensures that the image does not deform. If the image size and filling area ratio are not consistent, black edges will appear, making it the default fill mode
Stretch: Filling without maintaining aspect ratio can cause deformation loss
Zoom: Cropping. Scaled to completely fill the available screen size while maintaining the aspect ratio

How to set fill mode

Settings in the Export Panel

The fill mode of placeholder images can be set in the AE export panel

API Settings

It can be set in PAGView, PAGImageView, PAGPlayer and PAGImage by the following method

- (void)setScaleMode:(PAGScaleMode)value

It can also be set through the system's built-in contentMode method in the PAGImageView on the iOS platform.

@property(nonatomic) UIViewContentMode contentMode;

If the above fill mode does not meet the requirements, it is supported to set the matrix of PAG rendering content or fill images through the following interface

// iOS
- (void)setMatrix:(CGAffineTransform)value;

// Android
void setMatrix(Matrix matrix);
