- CSEDIT - A Simple Font Editor by Matt Pritchard
-
-
- CSEDIT is distributed with MODEXnnn.ZIP, the general purpose MODE X
- Library for VGA Graphics.
-
- WHAT YOU NEED TO RUN CSEDIT:
-
- * A Vga Monitor
- * A Microsoft Compatible Mouse
-
- A Mouse is most definitely required, as the keyboard is used for
- nothing except entering file names.
-
- FILES NEEDED IN THE CURRENT DIRECTORY:
-
- CSEDIT.EXE - The Font Editor Program
- CHARSETS.CS - The Font Editor's Internal Fonts
- PALETTE.CS - The Font Editor's Palette
- MOUSEIMG.CS - The Font Editor's Mouse Pointer
-
- SAMPLE FONT FILE THAT SHOULD BE INCLUDED:
-
- SYSTEM.FNT - The Font used by CSEDIT.EXE
- INVERSE.FNT - An Inverted version of SYSTEM.FNT
- SPACEAGE.FNT - A Futuristic, Tech style font
- ROM_8X8.FNT - The Lower 128 characters from the VGA BIOS Rom
-
- WHAT IT EDITS:
-
- 8 by 8 character fonts, 128 characters at a time. 2 fonts at a time.
-
- HOW IT WORKS/FEATURES:
-
- CSEDIT allows the user to edit 2 different font groups at a time,
- which may be loaded and saved separately.
-
- A enlarged character grid allows the user to edit individual pixels
- on a selected character.
-
- The Following operations can be performed on a single character or
- simultaneously on a selected block of characters.
-
- * Shift the selected character(s) in any direction
- with or without clipping at the edges.
- * Vertically Flip the selected character(s)
- * Horizontally Flip the selected character(s)
- * Rotate the selected character(s) 90 Degrees Clockwise
- * Rotate the selected character(s) 90 Degrees Counterclockwise
- * Clear the selected character(s)
- * Invert the selected character(s)
- * XOR the selected character(s) with other character(s)
- * AND the selected character(s) with other character(s)
- * OR the selected character(s) with other character(s)
- * Copy the selected character(s) to another position or font.
-
- An UNDO feature allows the reversal of the most recent operation.
-
- DESCRIPTION OF OBJECTS/FEATURES FROM THE TOP DOWN:
-
- Character Grid: (RED) Box in Upper Left corner of screen. This is
- where you edit an individual character. The Left Button sets the
- pixel the mouse pointer is on, while the Right Button clears that
- pixel.
-
- Scroll Buttons: The Four Scroll Buttons are labeled with directional
- arrows, and arranged in a diamond pattern. Left Clicking on a
- directional button will scroll the currently selected character
- in that direction, with the pixels on the edge rolling off and
- appearing on the other size. Right Clicking will prevent the
- pixels from rolling to the other side.
-
- Vertical Flip Button:
- Horizontal Flip Button: Clicking these buttons will flip the pattern
- of the currently selected character(s) around the indicated axis.
- i.e. the top row will be swapped with the bottom row, etc. or the
- left row column will be swapped with right column, etc.
- depending upon which button you push.
-
- Invert Button: Clicking this button causes all pixels in the selected
- character(s) to flip flop between on and off.
-
- Clear Button: Clicking this button erases the selected characters
-
- Rotate Buttons: Clicking these buttons will rotate the pattern in the
- selected character(s) 90 degrees in the indicated direction.
-
- XOR Button: Clicking this button will let you XOR the currently
- selected character(s) with other character(s) in either font.
- The Button will turn RED, indicating that it is waiting for
- you to click on the desired character (or upper left corner
- of the desired block of characters) in either the Red or Green
- Character Set Displays. Clicking anywhere else will abort this
- process without doing anything. If you click on (any of) the
- selected character(s) the operation is aborted. If a block is
- selected and the character you click on is in a position where
- it can't represent the upper left corner of a block of the same
- size, then the operation is not performed.
-
- AND Button & OR Button: These buttons work just like the XOR Button
- except that the Binary operation performed is either an AND or OR
- depending upon which button you have selected.
-
- COPY Button: This button lets you copy a character or selected block
- of characters to another area in the current font or the other
- font. After clicking, the button turns RED and works much like
- the XOR Button. Clicking on a valid position in either font
- window will copy the selected character(s) to that location.
-
- MODE Button: Clicking this button toggles the editor between BLOCK
- mode and CHARACTER mode. The current mode is displayed on a plate
- at the top of the screen, just to the right of the enlarged
- character grid. In character mode the plate will read "CHAR" and
- the currently selected character is displayed just to the right
- of the plate. In Block mode the plate will read "BLOCK" and the
- enlarged character grid is disabled.
-
- UNDO Button: Clicking this Button will UNDO or reverse the effects of
- the most recent operation.
-
- QUIT Button: Clicking this button will return you to DOS. Any loaded
- fonts are not saved, and no confirmation is given.
-
-
- GREEN FONT AREA: This area displays one of the current fonts which
- can be edited. The characters are display in order from #0 to #127
- from the upper left, going right, then down. The Font Box is 32
- characters wide and 4 characters Tall. When the editor is in
- character mode, just point at and Left Click on the character you
- wish to edit and a Cyan box will appear around that character.
-
- * If you Right Click on a character, the last current character,
- which will still appear in the enlarged character grid, will be
- copied onto the character you pointed at, replacing it. This is
- a shortcut for copying characters: You can hold the right button
- down an fill in a large area with a single character pattern.
- When the editor is in Block Mode, you select an area by clicking
- on any corner of the desired block. Then drag the mouse to the
- opposite corner while holding down the left button. A Cyan Box
- will stretch to surround the selected block of characters.
-
- GREEN FONT FILE NAME BOX: This Text Box is used to enter the name
- of a font file to load or the name to save the current Green font
- as. Just click on the Box, and it will change color and a
- flashing cursor will appear. Now you type in a filename or edit
- the existing filename. Press <RETURN> or click outside the text
- box to end editing.
-
- GREEN FONT LOAD BUTTON: Clicking this button will load the font file
- that is named in the Green File name box. If no name is given or
- no such file exists, then nothing will be loaded.
-
- GREEN FONT SAVE BUTTON: Clicking this button will save the current
- font in the Green Font Area under the name given in the File Name
- Box. If a Valid name is not provided, nothing will be saved.
-
- RED FONT AREA: This is just the same as the GREEN FONT AREA; providing
- you with the ability to copy and edit between multiple fonts.
-
- RED FONT FILE NAME BOX: This works just like the GREEN FONT FILE
- NAME BOX.
-
- RED FONT LOAD BUTTON: This works just like the GREEN FONT LOAD BUTTON.
-
- RED FONT SAVE BUTTON: This works just like the GREEN FONT SAVE BUTTON.
-
- Message Bar: At the very bottom of the screen, this Bar will display
- information and messages for various functions.
-
-
- FONT FILE FORMAT:
-
- BINARY Image, in order of character. The format is identical to that
- used by the VGA ROM. The Files will be exactly 1024 (128 * 8) bytes
- long.
-
- CHARACTER: 8 Bytes
-
- FONT: Array (0 to 127) of CHARACTER
