Image File

Name and directory of the image file (example: “C:\Programme\images\logo.bmp”) CODESYS supports the following image formats: BMP, EMF, GIF, ICO, JPG, PNG, SVG, and TIFF. Please note that a controller may not support all formats.

Whether or not you can use images formatted as scalable vector graphics (*.svg) depends on the operating system. Any necessary information is located in the device description of the hardware vendor.
What do you want to do with the image file?
Remember the link

CODESYS saves only the link. CODESYS automatically updates any changes to an image file in the image pool. You must ensure that the path of the image file does not change.

When saving the project as an archive, CODESYS embeds the image file in the project archive.
Remember the link and embed into project

CODESYS copies the image to the image pool and the link information is retained. In this way, CODESYS recognizes any changes to the image file and then update the image pool can as needed. This behavior is controlled with the options in the next table.

Embedded image files increase the memory requirement of the project.
Embed into project

CODESYS copies the image to the image pool. If the image file is changed again afterwards, then it is not updated in the project. For libraries, you must embed the image in the project.

Embedded image files increase the memory requirement of the project.
