Colour Manipulation

I've got an app that allows the user to display an image using a variable number of colours (2-24 colours). In addition, the user can specify upper and lower thresholds so that all pixels below a specified value are displayed using a colour such as black and all pixels with values above a

Re: use-livecode Digest, Vol 163, Issue 13

Hi HH Thanks for the advice, it was the paintCompression that caused the problem. In the IDE it defaults to PNG but in the standalone it defaults to RLE instead. As I didn't set it, the value was the default for the environment! I simply added: set the paintCompression to png to

Setting LD_LIBRARY_PATH

Has anyone successfully set the environment variable LD_LIBRARY_PATH for Mac/Linux apps? I've found that I can set the variable using: put tValue into $LD_LIBRARY_PATH and it appears to be set as far as the IDE is concerned. However, if I use the shell command to display the value of

Standalone Magnify Problem

Wrapping Android Speech-to-Text?

Having got Android speech input working, how easy would it be to do a similar thing to wrap Android's speech-to-text facility? I understand that it uses an on-line link to Google's voice input resources, which would be great for a number of purposes. Obviously, off-line would be better still,

Comparing 2 Spoken words, FFT function in LiveCode?

Re: Atkinson dither algorithm & 'for each' loop

One note of caution regarding the use of the "repeat for each" loop, whilst you will get a loop iteration for every value in the collection (fldhexa3 in your example), you are not guaranteed the order in which they will occur. This doesn't matter in a lot of cases but does matter when the
