LoadImageSheet (Function)

In french: ChargePlancheImage

Loads an image sheet in memory so that it can be used later by gImage.

Example

// The MULTI.BMP image includes 130 components
// No border will be displayed around each one of these components
LoadImageSheet(2, "MULTI.BMP", 16, 16)
// Display the images in a graphic list
FOR Subscript = 1 to 10*13
ListAdd(LIST_GraphicList, gImage(2, Subscript))
END

Syntax

<Result> = LoadImageSheet(<Image Identifier> , <Image Name> , <Image Width> , <Image Height> [, <Border>])

<Result>: Boolean

True if the image sheet was loaded in memory,
False otherwise.

<Image Identifier>: Integer

Identifier of image loaded in memory (included between 1 and 9). If this identifier is already used, the loaded image replaces the previous image. This identifier will be used by gImage.

<Image Name>: Character string

Name and full (or relative) path of image to load. A UNC path can be used.
No relative path or UNC path can be used.

<Image Width>: Integer

Width of an image found in the image sheet.

<Image Height>: Integer

Height of an image found in the image sheet.

<Border>: Optional character

"C" if no border must be displayed around each drawing. By default, a 1-pixel border is displayed around each drawing found in the image sheet.

Remarks

Numbered drawings

The image sheets includes several drawings organized in rows and columns. All these drawings must have the same size and they can be enclosed in a 1-pixel border.

The drawings are numbered from 1 to <Number of Rows> * <Number of Columns> from left to right and from top to bottom.

Notes:

Unlike LoadImage, if the number of drawings changes in the image, the images displayed will not be truncated and the corresponding code will not have to be modified.
Versions 21 and later
gImageExists is used to find out whether an image was loaded in memory by LoadImage or LoadImageSheet.
New in version 21
gImageExists is used to find out whether an image was loaded in memory by LoadImage or LoadImageSheet.
gImageExists is used to find out whether an image was loaded in memory by LoadImage or LoadImageSheet.

Limits

LoadImageSheet must not be used in the code of the project. Indeed, this function must be used in the window where the image must be handled.
