Is there something to the assert from my app? What event occurs for it to fail the assert? Is there a requirement from jpegsrc that must be configured in? In the ./configure for IM I do see a message about it not passing the preprocessor test but passing the compile test for the jpeg test. I'll post ...

Here is the output of the test app. /usr/local/MyDir/Test # ./test 2013-05-07T20:57:35+00:00 0:00.020 0.020u 6.8.4 Trace Magick: utility.c/GetPathComponent/1194/Trace /usr/local/MyDir/Test/test 2013-05-07T20:57:35+00:00 0:00.030 0.030u 6.8.4 Trace test: utility.c/GetPathComponent/1194/Trace /usr ...

Reproduced on newest version IM (v5.8.5-4).

Debug log identical. Same assert; 'Zoom: wand/magick-wand.c:295: MagickGetException: Assertion `wand->signature == 0xabacadabUL' failed.'

I can not run 'convert' on the target as the target has a space contstraint. But I can build it on the host (for the host) and it see what happens. I added 'setenv ("MAGICK_DEBUG","trace",1);' to the Zoom code just above the Wand Genesis and got the following: 2013-05-07T15:33:15+00:00 0:00.280 0 ...

In another tree of this forum I was asking about the proper way to handle a char* image in memory and I feel I ran into a bug in MagickReadImageBlob(). The environment is an embedded DaVinci (DM6446) architecture, using FC6 as the host, and cross compiling all the libraries. The version of IM is 6.8 ...

I do not know if this will help as I did this for cross compiling. But in the ./configure you should have --with-jpeg=yes and be pointing to the right include directories, and kernel dir. When the ./configure is finished it should say something like "--with-jpeg=yes yes " and above it you should see ...

Magick: I guess some code might help. I should also mention that using -DMAGICK_DEBUG seems to have no efffect. What is the correct syntax. I have added it to the cross compile, and the application's makefile to no avail. I have even tried 'export MAGICK_DEBUG'. Your earlier answer is a little bit ...

Still continuing to debug. Exception handling is good at reporting the status. At first I found I was not passing it the buffer properly as it reported the buffer was not a JPEG format. Fixed a problem with indirection, and now it calls into MagickReadImageBlob (wand, imgBuffer, image_len); and it ...

Thanks. It is set on the ./configure. However the above error seems to be that I didn't do a setformat before calling the MagickReadImageBlob. Now it tells me the source file is not a jpeg. But then that was an improper indirection (jpegbuffer versus &jpegBuffer) , and for some reason the first two ...

OK. fair. But what I posted is not the live code and it does checks the return of status(es) when I call an ImageMagick API. I beefed it up a bit with your suggestion, and the MagickReadImageFromBlob() is returning a "nodecodedelegate" error. I doublechecked and I do have libjpeg and the ./configure ...

I am a noob with Imagemagick so please bear with me. I am developing an application where I have a jpeg image in a memory buffer. Normally it just gets copied to a framebuffer and is displayed. What I have to do is Zoom in on the image. Here is basically what I am doing so far. Zoom_in_on_Image ...
