Are there inputs that will make them choke that shouldn't ? I currently don't have much time, so i only done a quick test of typical poison characters "&()[]{}^=;!'+,`~". Work: set "TestVar=HKEY_CURRENT_USER/EUDC/666/myteststring" set "TestVar=HKEY_CURRENT_USER(EUDC/666/myteststring" set "TestVar=H...

I found an error, which was shifting the wrong value: ::buggy set /a "%4.index1=(%4.b1<<2) + (%4.g1<<1) + (%4.r1), %4.r1=(%4.r1+(%4.isDarkGray<<1))<<6, %4.g1=(%4.g1+(%4.isDarkGray<<1))<<6, %4.b1=(%4.b1+(%4.isDarkGray<<1))<<6" ::bugfixed: set /a "%4.index1=(%4.b1<<2) + (%4.g1<<1) + (%4.r1), %4.r1=((%...

I'm not sure which values i should see as an error, so i don't know what to search for. Maybe you could give me the pixel(s), the error(s) and what you would like to see instead (i changed the main loop, so you could mark that pixel with a red X): set /A "pixel.x=0, pixel.y=0, image.width=102" set "...

Ad hoc i can't see a statement or command that XP would not support, or use differently than the newer versions. The only potential risks of incompatability i see are: - The usage of the localization dependend variables "date" and "time" (so it could happen on all windows versions). - External execu...

But wouldn't it have been better to average the three colors i.e. (R + G + B) /3 ? The idea behind RGB is, that components agree on the color produced. It doesn't match how humans experience color, though the result is somewhat acceptable. Would "L" be the brightness/lightness? English is not my mo...

Can you explain what you did here? :: set /a "%4.MIN3=-((%22-%11)>>32)*(-((%33-%22)>>32)*%3 - ((%22-%33)>>32)*%2) - ((%11-%22)>>32)*(-((%33-%11)>>32)*%3 - ((%11-%33)>>32)*%1)" :: set /a "%4.MAX3=-((%22-%11)>>32)*(-((%33-%11)>>32)*%1 - ((%11-%33)>>32)*%3) - ((%11-%22)>>32)*(-((%33-%22)>>32)*%2 - ((%...

As said above, i assumed linear distances of the colors in RGB-space: The main advantage is, it is easy to compute, because color distances are just euclidean distances over the coordinates of the RGB colors. The main issue is, that human perception of color is everything but linear. Typically that ...

I've replaced the grayscale algorithm, the (unoptimized - but hopefully bug-free) result is the following mapping function: :toColorTable R G B return var :: part 1 (sloppy is sufficient) set /a "%4.r1= -(-(%1>>6)>>2), %4.g1= -(-(%2>>6)>>2), %4.b1= -(-(%3>>6)>>2), %4.isDarkGray=%4.r1*%4.g1*%4.b1" se...

Ok, i somehow missed the fact, that the difference between 0 and 95 isn't 40... :oops: . Your solution already finds the best color match; however this is my try: :: color function style set /A "%4=(((%1)-35)/40+((%1-48)>>8)-((%1-74)>>8))*36 + (((%2)-35)/40+((%2-48)>>8)-((%2-74)>>8))*6 + (((%3)-35)/...

I'm not sure what you mean, the above computations should return an index (i) for the indexed color (r_i, g_i, b_i) with the minimal error to the given color value (r, g, b) - at least for any system, that uses the above colour table predefined by Microsoft: - The formular for (2) should return the ...

The color map (at least on my pc) is piecewise linear. 1) Indices 0x00 - 0x0F contain the most non-linear part: ( 0, 0, 0), (128, 0, 0), ( 0, 128, 0), (128, 128, 0), ( 0, 0, 128), (128, 0, 128), ( 0, 128, 128), (192, 192, 192), (128, 128, 128), (255, 0, 0), ( 0, 255, 0), (255, 255, 0), ( 0, 0, 255),...

I assume the error is caused by using the wrong environment variable named "Aufruf:" instead of "Aufruf", like you did in "Linie2.bat":

If i remember correct, then you can find those in the Templates for Parallax zip-file IcarusLives linked somewhere above, but under a diffferent name:
- "template1.ppm" is "cloud1.ppm"
- "template2.ppm" is "mountain1.ppm"
- "template3.ppm"should contain another mountain version.

The following might help you: Though i would add debug messages (using echo) and pauses, to see the program flow.
In case you don't have a visible console on login, you might redirect the echoes and avoid the pause commands instead.

I actually can't test it, but it might be the space characters, that break the value early, so you might encapsulate the value "c:\Program Files\Common Files\Corel\" in doublequotes.
