[fpc-pascal] writing to shared memory
Hi, I have the example code working to write and read string to shared memory. I'd like to write and read other things than strings (integers, Booleans, ...) to the shared memory. For writing strings, you use strpcopy. Which functions can be used for other types? I was thinking of memcpy but that doesn't seem to exist under freepascal. Thx, Tom Carly ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

[fpc-pascal] fpImage resample via interpolation
As far as I can see, fpImage has for StretchDraw only the TMitchelInterpolation. The current implementation has a few drawbacks: - it creates a temporary image for resizing horizontally. If you have to resize big scanned images or gis data this makes trouble. - it computes all factors each time for every pixel - it seems to only support shrinking by up to a factor of two. I have written an interpolation that does not require a temporary image (only a small buffer for a few lines), pre computes the factors and supports any shrink factor. It is about 250 loc just like the TMitchelInterpolation, needs less memory and is about twice as fast. I will contribute it to fpImage. At the moment it uses a linear distribution for enlarging. I'm not yet sure if I should use the Mitchel distribution or a Gauss distribution. Maybe someone can give me some advice.

Then why declaring a procedure with exactly the same signature (the original has been turned off) inside system unit doesn't stop the compiler from complying "unknown compilerproc fpc_write_text_shortstr"? -- View this message in context: http://www.nabble.com/fpc_write_text_shortstr-%28case-sensitive%21%29-tp20712874p20727839.html Sent from the Free Pascal - General mailing list archive at Nabble.com. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] MIDI processing unit
I'm writing a compiler for my own music programming language producing MIDI files as result. Is there any MIDI processing unit for helping me? Doesn't have to be cross-platform, at least it must work for Windows / Linux. -- View this message in context: http://www.nabble.com/MIDI-processing-unit-tp20728794p20728794.html Sent from the Free Pascal - General mailing list archive at Nabble.com. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
