[英]How to only set the width for a paperclip uploaded image?
I am uploading a large image to my model using Paperclip. 我正在使用Paperclip将大图像上传到我的模型。 I'd like to only set the width of the image and let it resize the height automatically.
我只想设置图像的宽度,让它自动调整高度。
has_attached_file :picture, :styles => { :large => "900", :medium => "300x300>", :thumb => "100x100>" }, :default_url => "/images/:style/missing.png"
In the :medium
and :thumb
sizes I am setting both height and width. 在
:medium
和:thumb
size我设置高度和宽度。 In the :large
I just want to set the width and let it be as high as it needs to be. 在
:large
我只想设置宽度,让它尽可能高。
Any suggestions? 有什么建议么?
Try using :large => "900x"
. 尝试使用
:large => "900x"
。 This should resize width to the desired value and keep original aspect ratio. 这应该将宽度调整为所需的值并保持原始宽高比。
Width only: :large => "900"
仅宽度
:large => "900"
Height only: :large => "x900"
仅高度
:large => "x900"
