All Routines are FAR, and is assumed that a DGROUP -; data segment exists and that DS will point to it on entry. -; -; For all routines, the AX, BX, CX, DX, ES and FLAGS registers -; will not be preserved, while the DS, BP, SI and DI registers -; will be preserved. -; -; Unless specifically noted, All Parameters are assumed to be -; "PASSED BY VALUE". That is, the actual value is placed on -; the stack. When a reference is passed it is assumed to be -; a near pointer to a variable in the DGROUP segment. -; -; Routines that return a single 16-Bit integer value will -; return that value in the AX register. -; -; This code will *NOT* run on an 8086/8088 because 80286+ -; specific instructions are used. If you have an 8088/86 -; and VGA, you can buy an 80386-40 motherboard for about -; $160 and move into the 90's. -; -; This code is reasonably optimized: Most drawing loops have -; been unrolled once and memory references are minimized by -; keeping stuff in registers when possible. -; -; Error Trapping varies by Routine. No Clipping is performed -; so the caller should verify that all coordinates are valid. -; -; Several Macros are used to simplify common 2 or 3 instruction -; sequences. Several Single letter Text Constants also -; simplify common assembler expressions like "WORD PTR". -; -; ------------------ Mode X Variations ------------------ -; -; Mode # Screen Size Max Pages Aspect Ratio (X:Y) -; -; 0 320 x 200 4 Pages 1.2:1 -; 1 320 x 400 2 Pages 2.4:1 -; 2 360 x 200 3 Pages 1.35:1 -; 3 360 x 400 1 Page 2.7:1 -; 4 320 x 240 3 Pages 1:1 -; 5 320 x 480 1 Page 2:1 -; 6 360 x 240 3 Pages 1.125:1 -; 7 360 x 480 1 Page 2.25:1 -; -; -------------------- The Legal Stuff ------------------ -; -; No warranty, either written or implied, is made as to -; the accuracy and usability of this code product.

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 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.

It is capable of providing -higher resoultions than the only "Official" 256 color mode, mode 13h. -(In quickbasic that is mode 13) - -2) Mode "X" comes in 8 different flavors: 320 or 360 pixels -horizontally, and 200, 240, 400, and 480 pixels vertically. - -3) Since mode X is not supported by the VGA BIOS, there is no built in -support for it. A program must provide its own routines for *ALL* -operations in Mode "X", including setting up the video mode. - -4) Unlike Mode 13h, which has one display page, Mode "X" allows from 1 -to 4 video pages, depending upon the resoultion selected. The reason -that Mode 13h has but one page is that it activates a VGA hardware -feature known as CHAIN4, which prevents access to all but 64K of VGA's -video RAM. CHAIN4 is what provides mode 13h's linear addres space. - -5) Unlike Mode 13h, where each 256 color (1-byte) pixel has a unique -address in the E000: segement, in Mode X there are Four (4) Pixels -at each address in E000: segment. The VGA's control registers allow you -to control which of the 4 pixels is currently available at an address. - -6) It is possible to use the VGA's control registers to operate on 2 or -more of the Pixels at the same address at the same time. The CPU can -write one color value, and set up to 4 pixels with that value at the -same time. - -7) Video RAM that is not being used for the current screen display can -be used to store images and patterns. These images and patterns can be -copied to other parts of the Video RAM 4 bytes (32 bits) at a time, -which is much faster than the 8 bits (1 byte) at time that is possible -over the ISA BUS.
