|
A slideshow graphic demo by Christian Groessler, written in C. The Lena image is a Anti-Correlation Digital Halftoned version. The Alfa 147 image comes from Alfa Romeo The other photos are by Davide Bucci. This version is more responsive to key presses and a simple effect to switch slides has been added. Call the program with the %e option, to enable the effect. The effect is implemented twice, once in C and in assembler. The pre-compiled binary is compiled with the assembler version. Use "make ASSEMBLER_EFFECT=1" to compile the asm version, by default the C version is built. This project is an example of mixing C and ASM code in a M20 cross-compile project. |
