Changes the 24-bit images registered and placed in a project to 16-bit images. Used when changing from a model that supports the number of colors described in [Before Conversion] in the table below to another model.
24-bit image data refers to images with a blink setting of 65536 colors in the [Reduce Colors] setting with blink, or images with 262144 colors or more in the [Reduce Colors] setting. If you have selected a model that does not support the number of colors described in [Before Conversion] in the table below, an error will occur in the error check if 24-bit image is placed in the project, and the project cannot be transferred. However, if you are using ST-6300TA or STC-6300TA, the transfer is possible because it is treated as a warning in the error check.

For the colors supported by each model, refer to the following.
