Stored procedures
Saves an image:
  • in a file in JPEG format.
  • in memory.
This image corresponds to the image contained in a Image control.
Remarks:
  • Only the visible part of the Image control is saved.
  • This function can only be used to save the images for screen resolutions up to 32 bits.
  • This function cannot be used with the Image controls found in the reports.
  • This function can also be used to save the modifications performed by ImageInfoModify on the Exif tags of an image.
  • Java Saving images in JPEG format is supported only if the application is run by the Java Virtual Machine (JVM) distributed by SUN. Images in JPEG format cannot be saved with other Java virtual machines.

Saving an image in a file in JPEG format Hide the details

<Result> = <Image control>.SaveJPEG(<File name> [, <Quality> [, <Exif tag>]])
<Result>: Boolean
  • True if the image was saved,
  • False otherwise. To get the details of the error, use ErrorInfo with the errMessage constant.
<Image control>: Control name
  • Name of Image control, Bar Code control or Web Camera control to use. The Image controls found in a report cannot be used.
  • Windows Mobile Name of the Image control or Web Camera control to use.
  • AndroidJava Name of the Image control to use.
<File name>: Character string (with quotes)
Name and full (or relative) path of JPEG file. A UNC path can be used. The file extension is optional.
Caution:
  • The destination directory must exist in order for the image to be saved.
  • The existence of the JPEG file is not checked. This file is automatically overwritten if it already exists.
Windows Mobile Name and full path of JPEG file to create. The file extension is optional.
<Quality>: Optional integer
Quality of the image saved. Value included between 1 and 100 (80 by default). Lower image quality translates into higher image compression rate and smaller file size.
<Exif tag>: Optional constant (or combination of constants)
Record Exif markers modified using the ImageInfoModify function:
imgAddThumbnailAdds a thumbnail into the image file (<File name>).
If there is a thumbnail in the image file displayed in the Image control, this constant is not taken into account.
Java This constant is not available.
imgProgressiveJPEGUsed to save the image in progressive JPEG format. This format is mainly used for the Web sites. It allows the pages to be loaded faster (the images being loaded and displayed progressively).
imgGrayScaleUsed to save the image in black and white ("Grayscale" display mode).
imgSaveTagSaves the Exif tags.
If there is a thumbnail in the image file displayed in the Image control, a new thumbnail is recalculated.
Java This constant is not available.

By default, the Exif tags are not saved, no operation is performed on the thumbnails.
This parameter is available only if <Control name> corresponds to the name of an Image control.

Saving an image in memory Hide the details

<Result> = <Image control>.SaveJPEG(<inMemory> [, <Quality> [, <Exif tag>]])
<Result>: Buffer
Byte string containing the image in JPEG format.
Then this byte string can be assigned to an Image control, saved in a file (fSaveText), sent via a network (with the Socket functions), ...
<Image control>: Control name
  • Name of Image control, Bar Code control or Web Camera control to use. The Image controls found in a report cannot be used.
  • Windows Mobile Name of the Image control or Web Camera control to use.
  • AndroidJava Name of the Image control to use.
<inMemory>: Constant
inMemory: Constant used to save an image in memory.
<Quality>: Optional integer
Quality of the image saved. Value included between 1 and 100 (80 by default). Lower image quality translates into higher image compression rate and smaller file size.
<Exif tag>: Optional constant (or combination of constants)
Record Exif markers modified using the ImageInfoModify function:
imgAddThumbnailAdds a thumbnail into the image file (<File name>).
If there is a thumbnail in the image file displayed in the Image control, this constant is not taken into account.

Java This constant is not available.

By default, the Exif tags are not saved, no operation is performed on the thumbnails.
This parameter is available only if <Control name> corresponds to the name of an Image control.

Image found in a Web Camera control

Only the image displayed when <Image>.SaveJPEG is run will be saved. To save this image, you can also use:
PHP

Pattern and PHP

In PHP, the drawing functions are based on the graphic library GD. This library is commonly used by the PHP hosting companies and therefore it is always enabled. The version of the GD library must be version 2.0.28 (or later). This library can be downloaded from the PHP site.
To enable (if necessary) this library locally, the following elements are required:
  • PHP installed.
  • the PHP.INI file found in the Windows directory must contain the following line: "extension=php_gd2.dll" (instead of ";extension=php_gd2.dll").
  • the php_gd2.dll file must exist in the directory of PHP extensions. This directory is defined in the PHP.INI file by the "extension_dir" variable.
Component: wd260pnt.dll
Minimum version required
  • Version 24
