This repository contains three "PC" projects:
* **libRgb2Hires**: a library to convert RGB image to the Apple II's HIRES format
* **Picture**: a program to convert a RGB png to a binary or an ASM that can be loaded to the HIRES memory pages of an Apple II.
* Source image must be 140x192. Pixels are anamorphic: twice wider than tall.
* **Picture**: a program to convert a RGB png to a binary or an ASM excerpt, that can be loaded to the HIRES memory pages of an Apple II.
* Source image must be 140x192. Pixels are anamorphic: they will be displayed twice wider than tall.
* Source image must contains six colors : BLACK, WHITE, ORANGE, GREEN, BLUE and PURPLE. The color may be approximation of the Apple II 6 colors. Please refer to the provided pic.
* **Tile**: given a RGB png tile sheet that satifies the same requirements as above, it extracts a 14x16 tile and converts it to ASM data. This data is not interleaved.

And one Apple II project:
* **Loader**: a program that will load and display a picture generated by the *Picture* program. A bash scripts is provided as an exemple to load the picture and the loader on an image disk. [AppleCommander](https://applecommander.github.io/) is required to do so.

# Running
A correct source image, *test.png*, is provided as an example. Convert it using Picture, then copy it on a dsk image along with the Apple II loader. You can use or refer to the provided script.
## Test
A correct source image, *test.png*, is provided as an example. Convert it using Picture, then copy it on a dsk image along with the Apple II loader. You can use or refer to the provided script in the *Loader_Apple2* folder.
