Hello all.

I have an application where I need to export very long (but not very high) images -- around 800x50000 -- or so from a Morph of the same size.  However, when I use any of the four Morph exportAs{PNG|BMP|JPEG|GIF} methods, the resulting files have their visual data truncated after about 10000 horizontal pixels.  However, the overall image is still the full length -- just the output image data is missing from the "end" of the image, and the metadata for the image indicates that it is the length it is supposed to me.  When the morph is viewed with inATwoWayScrollPane, all of the data is visible, so it is the export that is truncating data.  An example of a truncated PNG is here: 

       http://boycenet.net/ccam/m22_ko_w_contact_f26_1.png

Does anyone know why this might be and what I might be able to do to output the full length of data?  I've looked through the code and can't find any hard coded limits of 10000 pixels in the output.

In case anyone is wondering, this output is a spectrogram of the vocalizations of a mouse that lacks a certain gene and thus makes it seem autistic, so it might be a model for autism in general, and the researcher is trying to analyze the voice patterns (at ultrasonic frequencies) over a long period of time (1 minute per sample from recordings taken at 196kHz sampling rate).  So, yes, we are trying analyze mouse squeaks with Squeak!

Thanks in advance for any insights.

         Best Regards,

                Ed Boyce
