- ASCII 1.1
-
- ASCII saver ⌐ 1993 Paul Huxham
- ImageFX ⌐ 1992, 1993 Nova Design
-
- ASCII is freely redistributable
-
-
- WHAT IS IT ?
- An ImageFX saver module that converts the main image buffer into a series
- of ASCII characters that when printed in small print will look similar
- to the original image.
-
- There are 4 demo images in the demo drawer. 2 of them are larger than 80
- columns, so use a text editor or a small font shell to view them.
-
-
- INSTALLATION
- Copy the ASCII module into ImageFX:modules/savers.
- Load ImageFX.
-
-
- USING ASCII
- Load an image into the main ImageFX buffer.
-
- Select Save and choose ASCII. You must use the 24 bit buffer save option.
-
- Choose a file - BE CAREFUL not to overwrite your original picture.
-
- You will be asked how many characters across you would like the image. The
- default value should fit the image 'on screen'.
-
- Next how many vertical characters make up the image. Aspect ratios are
- discussed below.
-
- Finally you are asked how many 'grey' levels the image should contain.
- This represents how many character values ASCII has to choose from when
- converting the grey scales in the image to actual characters.
-
- After a short time (on a '040 at least) the image should be completed.
-
- The top line of the generated file contains the actual width, height and
- number of grey levels so you can recreate the image.
-
-
- OPERATIONAL TIPS
- Make the images twice as large as the default and use a font half as
- large as normal topaz 8 to view the images to increase the amount of
- information on screen.
-
- Convert the image to grey scale first and make sure there is an even
- spread of grey levels across the image.
-
- Crop the image to remove unwanted portions of the picture first and then
- convert to characters.
-
-
- ASPECT RATIOS
- Heres a guide for some of the various display modes:
-
- Lores &
- Hires Interlaced Are already 1:1 so no adjustments are necessary.
-
- Lores Interlaced Either double the size horizontally or halve vertically.
- Hires Either halve the size horizontally or double vertically.
-
-
- BUGS
- At the moment, ASCII only looks at the RED portion of an image to save
- time whereas I should look at a greyscale representation of the RGB values.
- There are better algorithms around, I should convert one.
