Description

Displays external JPEG or BMP image in a separate window.

First parameter sets file to load and requires either

a) folder path + video file name, or
b) path macro + video file name

Second parameter is optional and can be used to center image window on the screen:

CENTER

Code Examples

**View JPEG file NewImage.jpg placed in folder c:\My Project
ViewImage("c:\My Project\NewImage.jpg","")

**View BMP file HotImage.bmp placed in <SrcDir> folder
**having window centered on screen
ViewImage("<SrcDir>\HotImage.bmp","CENTER")

Additional Info

Position of image window is saved and will be used on the next window opening if second parameter (CENTER) is not set.

Description

Replaces current image of specified Bitmap, HotSpot or Polygonal HotSpot object with an external JPEG or BMP file.

Use first parameter to set Bitmap object label, for example:

MainImage

Second parameter sets file to load and requires either

a) folder path + video file name, or
b) path macro + video file name

Code Examples

**Replace image in bitmap object labeled MainImage with JPEG file
**NewImage.jpg placed in folder c:\My Project
ReplaceImage("MainImage","c:\My Project\NewImage.jpg")

**Set image in hotspot object labeled ColdSpot from BMP file
**HotImage.bmp placed in <SrcDir> folder
ReplaceImage("ColdSpot","<SrcDir>\HotImage.bmp")

Additional Info

Using this command without second parameter will clear image in the specified object:

ReplaceImage("FacePicture","")

Description

Sets status of background color under Bitmap object. If used, Bitmap object is filled with background color before displaying image.

Use first parameter to set Bitmap object label, for example:

MyImage

Second command parameter enables or disables image back color:

• 1 : sets image background color on
• 0 : sets image background color off

Code Examples

**Set image background color on for Bitmap object "MyImage":
UseImageBkgColor( "MyImage","1")

**Set image background color off for Bitmap object "MyImage":
UseImageBkgColor( "MyImage","0")

Additional Info

Use SetImgBkgColor command to set image background color.

Description

Sets image background color.

Use first parameter to set Bitmap object label, for example:

BigImage

Color setting uses RGB ( Red, Green, Blue) system containing 3 components.

Each component can have one of 256 levels. Greater value of component increases color intensity. If you specify value 0, color component will not be used. Value 255 uses maximum color intensity.

Second parameter for SetImageBkgColor is a comma-separated array of string values, each representing one RGB component (first: red, second: green, third: blue) in value range 0-255.

 

Example of second parameter:

150, 79, 205

Put together, command with parameters looks like this:

SetImageBkgColor("BigImage"," 150, 79, 205")

You can also use string variable for color setting:

color$=' 150, 79, 205'
SetImageBkgColor("BigImage","color$")

Code Examples

**Set blue background color for image labeled "RearImage":
SetImageBkgColor(" RearImage ","0,0,255")

**Set cyan background color for image labeled "RearImage" using
**string variable as a color source:
MyColor$='0,255,255'
SetImageBkgColor(" RearImage ","MyColor$")

Description

Sets starting point (origin), relative to the top left image corner, that will be used for image resizing and rotation.

Both resizing and rotation will be performed around this point.

Use first parameter to set Bitmap object label, for example:

RotoImage

Second command parameter consists of two coordinates.

Horizontal (X) coordinate, for e.g.:

80

Vertical (Y) coordinate, for e.g.:

30

Coordinates in second parameter are separated with commas, so here's an example of complete command:

SetImageOrigin("RotoImage","80,30")

Code Example

**Set starting point for object "RotoImage" to 154 (X), 84 (Y):
SetImageOrigin( "RotoImage","154,84")

Description

Resize the Image Object to the new size specified using the origin as the transformation center.

Use first parameter to set Bitmap object label, for example:

AlterImage

Second command parameter consists of two coordinates.

Horizontal (W) coordinate, for e.g.:

80

Vertical (H) coordinate, for e.g.:

60

Coordinates in second parameter are separated with commas, so here's an example of complete command:

Code Example

**Resize Bitmap object image "AlterImage":
ResizeImage("AlterImage","80,30")

**Set image Origin to Right-Bottom corner and then resize image "AlterImage" to half size of the original image:
IW=ImageWidth(AlterImage)
IH=ImageHeight(AlterImage)
SetImageOrigin("AlterImage","IW,IH")
ResizeImage("AlterImage","IW/2,IH/2")

Description

Rotates Bitmap object image relatively from current angle.

Use first parameter to set Bitmap object label, for example:

RotoImage

Second command parameter sets relative rotation angle in degrees.

Value in degrees can be either positive or negative. For e.g.:

80 - rotates image 80 degrees clockwise

-80 - rotates image 80 degrees counterclockwise

Code Examples

**Relatively Rotate image in Bitmap object "RotoImage"
**45 degrees clockwise
RotateImageRel( "RotoImage","45")

**Relatively Rotate image in Bitmap object "RotoImage"
**45 degrees counterclockwise
RotateImageRel( "RotoImage","-45")

Description

Performs absolute rotation of Bitmap object image in degrees, starting from 0 (default object angle).

Use first parameter to set Bitmap object label, for example:

RotoImage

Second command parameter sets absolute rotation angle in degrees.

Value in degrees can be either positive or negative. For e.g.:

80 - rotates image 80 degrees clockwise

-80 - rotates image 80 degrees counterclockwise

Code Examples

**Perform absolute rotation of image in Bitmap object "RotoImage"
**45 degrees clockwise
RotateImageTo( "RotoImage","45")

**Perform absolute rotation of image in Bitmap object "RotoImage"
**45 degrees counterclockwise
RotateImageTo( "RotoImage","-45")

Description

Sets displayed part of Bitmap object image using coordinates from the second command parameter. This can be used when image has a different width or height than Bitmap object canvas.

Use first parameter to set Bitmap object label, for example:

BigImage

Second command parameter sets image section upper left coordinates.

When image is smaller than Bitmap object canvas, use positive coordinates to move displayed section to left (x) and up (y).

Positive horizontal (X) coordinate, for e.g.:

80

Positive vertical (Y) coordinate, for e.g.:

30

When image is larger than Bitmap object canvas, use negative coordinates to move displayed section to right (x) and down (y).

Negative horizontal (X) coordinate, for e.g.:

-80

Negative vertical (Y) coordinate, for e.g.:

-30

Coordinates in second parameter are separated with commas, so here's an example of complete command:

ScrollImageView ("BigImage","-80,-30")

Code Examples

**Display section of Bitmap object "BigImage" starting with coordinates
**-130 (X), -80 (Y)
ScrollImageView( "BigImage","-130,-80")

**Display section of Bitmap object "SmallImage" starting with coordinates
**30 (X), 80 (Y)
ScrollImageView( "SmallImage","30,80")

Additional Info

To obtain actual X/Y position of the left top corner of an image inside the Image object use ImageScrollX, ImageScrollY functions.

Description

Zooms in or out image of specified Bitmap object.

Use first parameter to set Bitmap object label, for example:

MapImage

Second command parameter sets zoom percentage. Default image zoom value is 100. You can use both lower and higher values than default one.

Zooming out to 80% of image original size:

80

Zooming in to 150% of image original size:

150

Code Examples

**Zoom out Bitmap object image "MapImage" to 50% of original:
ZoomImageView( "MapImage","50")

**Zoom in Bitmap object image "MapImage" to 200% of original:
ZoomImageView( "MapImage","200")

Description

Resets size and rotation angle of specified Bitmap object.

Use first parameter to set Bitmap object label, for example:

AlterImage

Code Example

**Restore Bitmap object image "AlterImage":
RestoreImage("AlterImage")
