Even though this step creates new images, as Mogrify documentation states, it is a dangerous tool and can easily destroy the original image. Then you need to make sure that the next image has an 1:1 aspect ratio, in this case a 128x128 image.īefore we start, make sure to have a backup in case something goes wrong. Images with different proportions can also be used, but they need to be ordered to prevent tile mismatching, for example lets say you have an image with 128圆4 resolution. And, lastly we are going to combine all these images into a single Texture Atlas. Once you are in the folder, we need to perform three actions, we need to convert multiple image types in a single one, then we need to resize them (in this tutorial I am going to resize images to 128x128), but you are free to choose the aspect ratio you want, be it 32, 64 or 256. In Windows 10 you have an option to open a folder in Windows PowerShell by right clicking that folder while holding the shift button (Shift+RClick), as shown in the image below. If you know how to navigate through folders using command line, you are free to skip the next part. We need to open that folder in the command line, you can achieve that through cmd.exe, or with Windows PowerShell or through Windows Explorer. Once you have ImageMagick installed, create or browse to a desired folder with all images you want to create your Texture set. There is a tutorial in this page, showing how to set Environment Variables in Windows 10. You can check if it is installed on the command line with the following command:Ĭode: magick identify -versionIf it is not available on your path, try to add manually to the System Path. At the time of installation there is an option that asks you to install legacy utilities, make sure to check it, because checking that box makes ImageMagick available to use through command line. The suggested package is " ImageMagick-7.0.11-1-Q16-HDRI-圆4-dll.exe", but if you have a 32bit Windows, you can download the Q16-HDRI-x86-dll.exe package. Well, for the sake of practicality of course, with ImageMagick we can convert dozens of single images into a readily available texture atlas which can be used by NGLE, Tomb Editor and even with the Classic Editor!īefore we jump into it, make sure to install ImageMagick Then I'm pretty sure you are going to ask, ImageMagick is capable of converting over 200 formats, including the most commonly available and used, such as PNG, JPEG, BMP and TGA. With it you can create, display, convert, modify and edit rasterized images. If there is only a single size image then it will be scaled as appropriate for the screen resolution.Hi everyone! I did something fun today, and I would like to share with you all.įor those who are wondering, ImageMagick is a free and open-source image manipulation software. If there are multiple sizes, your app will automatically choose the most appropriate size to display at runtime based on the type of screen being used. In your source code you refer to the image by its name as shown in the Navigator. You can use the contextual menu to open the image in the system default image editor or to show the location of the image on the drive. Press the Delete key to delete the image. You can click on any image in the Image Set Editor to select it. It is often convenient to create a ProjectImages folder next to your project where you place your images files and then drag them from there. This means if you move the external files or copy the project, the images may not be found. These images are not copied to your project, but are referenced as external items. Some tools (such as Photoshop) do not properly set the DPI which can cause Xojo to interpret the image as the wrong size. Make sure that that the tool you use to create or edit your images properly sets the image DPI (dots per inch). For example if your 1x image is 64圆4 72DPI, then the 2x image must be the same ratio (1:1) and would typically be 128x128 72DPI or 64圆4 144DPI. You can add additional 2x and 3x resolutions for use by HiDPI screens.Īll images must have the same aspect ratio. This size is used for standard (non-HiDPI) screen resolutions. When you drag an image into your project it is automatically assigned to the 1x size. The Image Set Editor displays three sizes for the image. The Image Set Editor lets you manage pictures and images dragged into your iOS projects and your desktop and web projects when the Supports HiDPI setting in Shared Build Settings is set to ON (this is the default on MacOS and Windows).
