PPT: Incorrect Arguments in Export Method Help Topic Example (169732)

MORE INFORMATION

The ScaleWidth and ScaleHeight arguments define the number of pixels that are used to scale the width and height of the graphic when it is exported as a CompuServe Graphics Interchange Format (.gif), JPEG File Interchange Format (.jpg), or Portable Network Graphics (.png) file. These arguments are ignored when exporting as a Windows Metafile (.wmf) file.

Keep the following tips in mind when setting the ScaleWidth and ScaleHeight arguments:

• The arguments must be set to a value greater than one. A value less than or equal to one results in the ScaleWidth and ScaleHeight arguments being ignored.
• The default type for the arguments is Long (or long integer). Only integer values are stored for variables of type Long. If you set the arguments to a decimal number, anything to the right of the decimal point is rounded to the nearest whole number. For example, setting ScaleWidth to 1.49 yields a graphic that is 1 pixel wide, and setting ScaleWidth to 1.50 yields a graphic that is 2 pixels wide.
• The graphic formats, .png, .gif, and .jpg, are exported at a rate of approximately 96 pixels per inch. ScaleWidth and ScaleHeight values of less than 24 pixels result in a graphic that is less than 0.25 inches for either dimension. A graphic of this size would rarely have enough detail to clearly represent the slide image.
