bitmap display/extraction

hi all, i have a severe problem, i have some pictures, they are mulcticolor only, so it should be easy to extract the image data from it, can anyone point me to a description of those .prg multicolor images?

btw. i have a font/charset ( 2x2) in png format, what is the easiest/fastest way to get a c64 charset from it? i would not like to write a converter for this .,..

can there be a program wich outputs the bytes (valued 0..3 so, to bits a pixel) only????

time is runing out...

Quote: hi, i stepped over this tool
PicChar v0.1
has anyone used it before ? how is the input format of this tool, there is no comment about accepted input formats, it seems that it rads just any type of file, but i am not sure in which format i have to use so that i can get what i want ... ;(


NO, It's from Scout... Don't use it, or it'll blow up your computer... ;-)
:-D

No realy, Use that tool! It's sure easier than moving all char-parts by hand... If the tool can do 4x4 chars?

*BOOM!*

The program converts any hires screen into a charset.
Even more than 1 pic can be used.
Yay!
I also have an unreleased version of PicChar which makes it possible to create an inverse charset if needed (eor #$ff :).
Double yay!

Also, for the people who struggle with the d018/dd00 settings I recommend D018 Manager

I recommend against it :)
Its not THAT hard and starting with tools you will always think of $d018 as an evil dark corner...

Yoh Trifox,why not rip another 2x2 somewhere.
Will save you lots of time and then figure it out without a deadline.
C64+Deadline is BAD!! ;)

A hires-Bitmap contains 2 colors each char, there is no unique backgroundcolor for the whole screen like there is in charset mode. So in every char congo had free choise to us black for 0 and 1 for white or vice versa. Congo has chosen to turn the upperleftmost pixel to 0, no matter if it was black or white.
