WBITMAP-LOAD-SYMBOL-FONT-EX

The WBITMAP-LOAD-SYMBOL-FONT-EX function generates a bitmap strip from multiple combinations of font, color and text.

This is particularly useful to generate icons from symbol fonts like Font Awesome or Material Design Icons.

Note - the feature is certified for Java 1.8.0_251 or higher. Previous Java versions may generate a bitmap smaller than the requested width.

Syntax:

CALL "W$BITMAP" USING WBITMAP-LOAD-SYMBOL-FONT-EX

imageWidth

WBITMAP-LSF-DATA

GIVING bitmapHandle

Parameters:

WBITMAP-LOAD-SYMBOL-FONT-EX	Constant
imageWidth	PIC 9(n)	Specifies the width in pixels of the bitmap frame. The function generates a frame for each character in the characters sequence and then combines all the frames into a bitmap strip. Regardless of the font size, characters will be resized to fit the width specified by this parameter.
WBITMAP-LSF-DATA	Group Item	Structure that hosts the information. This group item, defined in isgui.def, has the following structure: 01 wbitmap-lsf-data. 03 wbitmap-lsf-element occurs dynamic. 05 wbitmap-lsf-font handle of font. 05 wbitmap-lsf-characters pic n any length. 05 wbitmap-lsf-color pic s9(10). wbitmap-lsf-font An handle of font as returned by the W$FONT routine or one of the internal fonts available in the runtime (e.g. SMALL-FONT). wbitmap-lsf-characters Specifies the list of characters that will be included in the bitmap strip. Use a national data item or literal if the font requires Unicode representation of the characters. wbitmap-lsf-color Specifies the color of the characters. A negative value is treated as RGB color while a positive value is treated as COBOL color. See Color management for more information. If not set, then the black color is used.

Return code:

bitmapHandle must be declared as PIC S9(9) COMP-4 and provides additional information:

> 0	Receives the handle to the bitmap
0	An error occurred, probably the font handle is invalid
