Update V4.6<\/strong><\/p>\n\n\n\n

The Data format<\/strong> and Data Structure<\/strong> Parameters for the export of Graphic LCD Fonts have been extended and split in two tabs on the Font Panel<\/strong>.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

The Tab names are Data<\/strong> and Struct<\/strong> and Header<\/strong><\/p>\n\n\n

There’s a choice between 4 different GLCD data structures<\/strong>.<\/p>\n\n\n\n

The Font character descriptors \/ Font Char Header information \/ can optionally be enabled or disabled and their order of appearance in the code defined. <\/p>\n\n\n\n

<\/p>\n\n\n\n

Character<\/strong> Descriptors \/ Font Char Header<\/strong><\/p>\n\n\n\n

Switch the needed descriptors to True<\/strong> or False<\/strong>, if you need them or not in your code export. the adjust then order of their appearance in the code at the right.<\/p>\n\n\n\n

Char Adress<\/strong> : It’s the Ascii Code of the Char (In the case of Editable Custom Fonts, you can adjust the Ascii Offset<\/strong> in the Data Parameters to adjust the Char address.<\/p>\n\n\n\n

Start Address : Start Address of the Data array of the char.<\/p>\n\n\n\n

Char Width Bits :<\/strong> Width in bits of the char.<\/p>\n\n\n\n

Char Height Bits<\/strong> : Height in bits of the char.<\/p>\n\n\n\n

Char Size Bytes<\/strong> : Size in bytes of the char.<\/p>\n\n\n\n

Char Size Bits<\/strong> : Size in bits of the char. Example : If the bottom right pixel of the char is X18 , Y31 (in the Char Grid of the Font Panel) + the X0 Y0 bits, so 19 bits in width x 32 bits in height, the Char size in Bits is 19 x 32 = 608 pixels<\/p>\n\n\n\n

An X <\/strong>and Y Offset<\/strong> system is available to remove lines of blank pixels<\/strong> in the code ( char background ) and save memory space. The blank lines at the top and at the bottom of the data are removed from the code output and replaced by Offset<\/strong>s in the descriptors.<\/p>\n\n\n\n

Char Spacing :<\/strong> Spacing adjustment in pixels chars. <\/p>\n\n\n\n
