- │ Overview │
- └──────────┘
- PATTERNS helps you quickly create and edit 8 byte user-defined patterns
- to be used in the setfillpattern() function. The program works much like
- an icon editor. You click on an editing grid to create/edit a pattern.
- A sample of the pattern is displayed and results are updated immediately.
- The program also shows the hex code that is being generated.
-
- You can create and edit 24 patterns and save them to a file. The program
- features a color bar so you can quickly pick the pattern color. When the
- pattern is saved to a file, the program will remember its unique color,
- and display it in that color the next time it is loaded.
-
- PATTERNS displays miniatures of all 24 patterns. To edit a pattern, just
- double-click on its miniature. The program will also write an annotated
- code file for all of the patterns.
-
- THIS PROGRAM IS SHAREWARE, AND TOOK MANY HOURS TO DEVELOP. IF YOU FIND
- PATTERNS USEFUL, KINDLY CONTRIBUTE TO THE SHAREWARE SPIRIT.

- ┌───────────────────────────────┐
- │ The setfillpattern() Function │
- └───────────────────────────────┘
- setfillpattern(char *pattern, int color) sets the current fill pattern to
- a user-defined 8x8 pixel pattern. The pixel pattern is determined by the
- char *pattern array. This char array consists of 8 bytes. Each byte will
- determine a row in the pattern.
-
- Whenever a bit in a pattern's byte is set to 1, the corresponding pixel
- is plotted. For example, the following user-defined fill pattern displays
- a checkerboard:
-
- char pattern[8] =
- {
- 0xAA, /* 10101010 = █ █ █ █ */
- 0x55, /* 01010101 = █ █ █ █ */
- 0xAA, /* 10101010 = █ █ █ █ */
- 0x55, /* 01010101 = █ █ █ █ */
- 0xAA, /* 10101010 = █ █ █ █ */
- 0x55, /* 01010101 = █ █ █ █ */
- 0xAA, /* 10101010 = █ █ █ █ */
- 0x55 /* 01010101 = █ █ █ █ */
- };
- ┌────────────────────────────────┐
- │ Designing Patterns is Painful! │
- └────────────────────────────────┘
- As you can see from the above brief explanation, there is nothing obvious
- that predicts what pattern will be generated by the pattern[]'s hex bytes.
- Without the PATTERNS program, one would have to know the bit sequence that
- was desired, and then which hex number it corresponded to. Lots of trial
- and error. But this is no longer an issue! PATTERNS takes care of all the
- background work and details, leaving you free to use your imagination.
-
-
- ┌────────────────────────────────┐
- │ How to Create a Pattern Design │
- └────────────────────────────────┘
- When PATTERNS first loads, the editing box (displayed as an 8x8 grid)
- contains Pattern #1 of Set #1 (which is empty until you save a pattern
- to this pattern set). Each row in the box corresponds to a byte in the
- char Pattern[8] array, and each cell in a given row represents a bit.
-
- To turn a bit ON, just click on it with the left mouse button. To turn it
- OFF, use the right mouse button. It's that simple! Note: you can drag the
- mouse across cells to quickly turn them ON or OFF. To change a pattern's
- color, click on the color bar. The default color is WHITE.
-
- As you create or edit a pattern, a sample of the pattern is displayed and
- will be updated as you make changes. Note also that PATTERNS displays the
- actual hex values generated in the Pattern[] array as you make changes.
- You can view a full-screen pattern sample by clicking on the Zoom button.
- The Clear pushbutton will clear the editing box, letting you start over.
-
-
- ┌───────────────────────┐
- │ How to Save a Pattern │
- └───────────────────────┘
- Saving a pattern is simple. Just click on the Save pushbutton. PATTERNS
- will write the Pattern[] array to a binary file called PATTERNS.DAT. This
- file is read each time that PATTERNS is loaded, letting you view and edit
- patterns at any time in the future.
-
-
- ┌───────────────────────┐
- │ How to Edit a Pattern │
- └───────────────────────┘
- PATTERNS supports 24 user-defined patterns. Miniature samples are shown
- in sets of 12. To edit a pattern, just double-click on the miniature. The
- program will import the pattern into the editing box. You can always tell
- which pattern is currently selected. The frame around the miniature sample
- will be highlighted.
-
- You can quickly switch between the 2 sets of 12 patterns by clicking on
- the More pushbutton. IMPORTANT!!! BE SURE TO SAVE YOUR WORK BEFORE YOU
- IMPORT A NEW PATTERN INTO THE EDITING BOX.
- ┌───────────────────────┐
- │ Generating C/C++ Code │
- └───────────────────────┘
- Of course, the whole purpose of this program is to create patterns that
- you can use in your program. PATTERNS will generate an ASCII file called
- PATTERN.CPP that contains the code for the current pattern. Just click on
- the C++ pushbutton. Here is a sample of a typical PATTERN.CPP file:
-
- // Code for Pattern #1, pattern set #2
- char Pattern[8] = {0xaa, 0x55, 0xaa, 0x55, 0xaa, 0x55, 0xaa, 0x55};
- setfillpattern(Pattern, 11);
-
- /* HEX BINARY RESULT
- ------------------------------------------
- Pattern[0] 0xaa 10101010 █ █ █ █
- Pattern[1] 0x55 01010101 █ █ █ █
- Pattern[2] 0xaa 10101010 █ █ █ █
- Pattern[3] 0x55 01010101 █ █ █ █
- Pattern[4] 0xaa 10101010 █ █ █ █
- Pattern[5] 0x55 01010101 █ █ █ █
- Pattern[6] 0xaa 10101010 █ █ █ █
- Pattern[7] 0x55 01010101 █ █ █ █
