# Fit
Resizes the image to fit into a specified **width** and **height** box, adds padding (image or solid color) to keep proportions, and delivers the resulting image via CDN.
**func=fit**
The padding can be customised using the following additional operations:
| Operation | Syntax | Description |
|---|
| gravity | gravity=X
X=[north|south][east|west] | sets the position of the image in the fit box |
| solid background | bg_color=X | bg_colour=X
X={hex color}|auto | defines a background color with a hex code, color name or automatically, based on the image palette |
| blurred background | bg_img_fit=1 | sets blurred image background |
| bg_blur=X | applies Gaussian blur to the background image |
| bg_opacity=X
X=0..1 | specifies background image opacity |
| bg_colourise=X | bg_colorize=X | defines a color to tint the background image |
| image upscaling | fit_enlarge=1 | allows upscaling smaller images to the desired dimensions (will result in inferior image resolution) |
## Gravity
| **northwest** | **north** | **northeast** |
| ------------------------------------------------ | -------------------------------------------------------------------------------------------------------- | ------------------------------------------------ |
| **west** | **center** \| **centre** (default) | **east** |
| **southwest** | **south** | **southeast** |

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.scaleflex.com/dynamic-media-optimization-dmo/transformations/image-optimization/operations/fit.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
