OK, so I have it figured out. Even though checking for the clut file reported it existed and that it was readable (using NSFileManager), apparently for some reason unknown to me it was not readable by 'convert'. The clut was in the main bundle (resource) folder (which is accessible by the app). I wr...

They are not null strings though - thus is confirmed as they are printed to my log with printf.

Does the same thing even if I hard code them. I mainly used vars here because it is easier to read.

Greetings, I am using ImageMagick 6.6.4-8 on iPhone OS 4.0. I am using the ConvertImageCommand() function with success in the iPhone simulator, but the same exact code is failing on a physical iPhone. The args that I am using are: char *argv[] = { "convert", filePath, "-colorspace&quo...

Greetings, I am trying out IM for the iPhone, and it works great! Just seems like something must be being cached to disk or something, because running filters seems much slower than some other iPhone apps that I have seen based on IM. Example: running the oil paint filter with a radius of 3 on an im...

Thanks Fred!

bubblwrap -t sin from your examples looks perfect!

But I am getting identical results using sin and arcsin which both appear to be an arcsin result.

I can show my test images if it might help....

Hey Fred,

I was wondering if you knew of a way to get a "reverse fisheye" effect?

I tried entering negative values but they are not accepted from your script.

Example, original on the left, inverse fisheye on the right:




Thanks!

Pete

That is Excellent!

Thank you very much both Fred and Pete!

Nice collection of scripts!

Do you know if it is possible to use the "convert" IM command from a C/C++ interface?

Greetings,

Can anyone recommend an approach to creating a zoom blur type filter?

The effect is similar to a motion blur, but has a center and the blur are rays from the center.

Any suggestions would be greatly appreciated!


Thank you.

Apparently MAGICK_MEMORY_LIMIT seems to control the maximum pixel cache for the heap otherwise it caches to disk.

MAGICK_MAP_LIMIT seems to control the maximum pixel cache otherwise it caches to disk.

If MAP limit is not using memory from the heap, what is it using before it caches it to disk?

Thanks for the link.

I am using MAGICK_MEMORY_LIMIT which works great, but I understand it also limits the disk pixel cache.

Is there a way to limit just the RAM and not the swap cache?

Thanks again!

Greetings,

I am just getting up to speed with ImageMagick and I am loving it!

Is there a limit memory option for the MagickWand API similar to the limit memory switch for the convert utility?

Thanks!
