Type: Texture2DContent
The bitmap data to convert to a font.

Type: ContentProcessorContext
Context for the specified processor.

Return Value

Type: SpriteFontContent
The font data.

Exceptions

Exception type	Condition
ArgumentNullException	input is null.
InvalidOperationException	A character cannot be mapped to a glyph index: it is already mapped to a glyph index.

Remarks

Each character should be arranged on the bitmap in a grid ordered from upper left to lower right. Monochrome characters should use white for solid areas and black for transparent areas. To include multicolored characters, add an alpha channel to the bitmap and use that to control which parts of the character are solid. Fill the spaces between each character and around the edges of the grid with a specific magenta color having the value Red:255 Green:0 Blue:255 Alpha:255. The processor packs the characters together as tightly as possible, eliminating any wasted space in the original grid.
