| | imgHCE | Homothetic extended centered: Image enlarged or reduced in size, respecting the proportions of the original image, so that the smaller side of the image is displayed entirely in the field and the image is centered in the field..
| | imgHCWIS | Homothetic without increasing size: If the image can be entirely displayed in the control, it is displayed at 100% and centered in the control. Otherwise, it is downsized, while maintaining its aspect ratio to fit and appear centered in the control. | | imgHE | Homothetic extended: Image enlarged or reduced while respecting the proportions of the initial image in order for the smallest side of the image to be entirely displayed in the control.

Observaciones - gImage can be used to insert an image:
- into the title and status bars of a window or into a Static Text control.
- into a Table control. In this case, the image must be inserted into a text column.
- To display a text over an image:
- Insert an image with gImage,
- Describe the background color of the text with gBackground and the Transparent constant,
- Display the text.
For example:
ListAdd(LIST_ListView, gImage(ImagePath) + gBackground(Transparent) + gCoord(0, 0) + ...
"Text")
- If a row of a Combo Box control displays an image via gImage, when this row is selected, the image is re-used in the main row.
Image height (List Box or Combo Box control) The height of the image displayed in an element of a List Box or Combo Box control is truncated to the number of pixels specified when the control was created ("Style" tab of the control description). Clasificación Lógica de negocio / UI: Código neutro
