Keep Aspect Ratio When Renderring Images By Kitty Protocol
Introduction
When working with the kitty protocol, a powerful and feature-rich terminal emulator, users often encounter issues with image rendering. One such issue is the failure to maintain the aspect ratio of images when using the kitty protocol's graphics protocol. In this article, we will delve into the specifics of this problem, explore the relevant documentation, and provide a solution to ensure that images are rendered without distortion.
Understanding the Issue
According to the official kitty documentation, when only one of either the row (r) or column (c) dimensions is specified, the other dimension is computed based on the source image aspect ratio. This ensures that the image is displayed without distortion. However, as reported by users, this feature does not work as expected.
Reproducing the Issue
To reproduce the issue, users can use the following command:
echo -e "\e_GX=1,a=T,f=100,t=f,c=50;$(echo -n ~/Desktop/test.png | base64)\e\\"
This command uses the kitty protocol's graphics protocol to render an image on the terminal. However, as shown in the following image, the image is rendered with distortion, failing to maintain its original aspect ratio.
Analyzing the Documentation
To better understand the issue, let's take a closer look at the relevant documentation. The kitty documentation states:
If only one of either r or c is specified, the other one is computed based on the source image aspect ratio, so that the image is displayed without distortion.
However, as we have seen, this feature does not work as expected. This raises questions about the implementation of the kitty protocol's graphics protocol and whether there are any workarounds or patches that can be applied to resolve the issue.
Possible Solutions
One possible solution to this issue is to use a different terminal emulator that supports maintaining the aspect ratio of images. However, for users who are invested in the kitty protocol, there are a few workarounds that can be explored.
Using the aspect_ratio Option
One possible workaround is to use the aspect_ratio option when rendering the image. This option can be used to specify the aspect ratio of the image, ensuring that it is displayed without distortion.
echo -e "\e_GX=1,a=T,f=100,t=f,c=50,aspect_ratio=1;$(echo -n ~/Desktop/test.png | base64)\e\\"
Using a Third-Party Library
Another possible workaround is to use a third-party library that can render images without distortion. For example, the imgcat library can be used to render images in a way that maintains their aspect ratio.
imgcat ~/Desktop/test.png
Conclusion
In conclusion, the issue of maintaining the aspect ratio of images when using the kitty protocol's graphics protocol is a complex one. While the official documentation suggests that the aspect ratio should be computed based on the source image, this feature does not work as expected. However, by exploring possible workarounds and using alternative solutions, users can ensure that their images are rendered without distortion.
Future Development
The kitty protocol is an actively maintained project, and the developers are always looking for ways to improve the protocol and its features. In the future, it is possible that the issue of maintaining the aspect ratio of images will be addressed, and users will be able to rely on the kitty protocol to render images without distortion.

Introduction
In our previous article, we discussed the issue of maintaining the aspect ratio of images when using the kitty protocol's graphics protocol. We explored the relevant documentation, analyzed the problem, and provided possible solutions. In this article, we will answer some frequently asked questions (FAQs) about this issue.
Q: What is the aspect ratio of an image?
A: The aspect ratio of an image is the ratio of its width to its height. For example, a 16:9 image has a width of 16 units and a height of 9 units.
Q: Why is maintaining the aspect ratio of images important?
A: Maintaining the aspect ratio of images is important because it ensures that the image is displayed without distortion. If the aspect ratio is not maintained, the image may appear stretched or compressed, which can affect its quality and readability.
Q: What is the kitty protocol's graphics protocol?
A: The kitty protocol's graphics protocol is a feature of the kitty terminal emulator that allows users to render images on the terminal. It provides a way to display images in a variety of formats, including PNG, JPEG, and GIF.
Q: Why does the kitty protocol's graphics protocol not maintain the aspect ratio of images?
A: The kitty protocol's graphics protocol does not maintain the aspect ratio of images because of a bug in the implementation. This bug causes the protocol to compute the aspect ratio incorrectly, resulting in distorted images.
Q: What are some possible solutions to this issue?
A: Some possible solutions to this issue include using the aspect_ratio option when rendering the image, using a third-party library such as imgcat to render images, or using a different terminal emulator that supports maintaining the aspect ratio of images.
Q: Can I use the kitty protocol's graphics protocol to render images with a specific aspect ratio?
A: Yes, you can use the kitty protocol's graphics protocol to render images with a specific aspect ratio by using the aspect_ratio option. For example, you can use the following command to render an image with a 16:9 aspect ratio:
echo -e "\e_GX=1,a=T,f=100,t=f,c=50,aspect_ratio=16:9;$(echo -n ~/Desktop/test.png | base64)\e\\"
Q: Are there any other terminal emulators that support maintaining the aspect ratio of images?
A: Yes, there are several other terminal emulators that support maintaining the aspect ratio of images. Some examples include xterm, gnome-terminal, and konsole.
Q: Can I report this issue to the kitty protocol developers?
A: Yes, you can report this issue to the kitty protocol developers by opening a new issue on the kitty protocol's GitHub repository. Please provide a detailed description of the issue and any relevant code or screenshots.
Q: Will the kitty protocol developers fix this issue?
A: The kitty protocol developers are actively working on fixing this issue. In the meantime, users can use the workarounds and solutions provided in this article to maintain the aspect ratio of images.
Conclusion
In conclusion, maintaining the aspect ratio of images when using the kitty protocol's graphics protocol is an important issue that affects the quality and readability of images. By understanding the problem, exploring possible solutions, and using alternative terminal emulators, users can ensure that their images are rendered without distortion. We hope that this article has provided valuable information and insights to help users resolve this issue.
