Hi.
Using QNX 4.25 and Photon 1.14.
How hard would it be to create a new driver to support TIFF, GIF or JPEG?
Has any one done this? I did a TIFF capture for our old data system which
wasn’t to bad to do.

Hi Augie,
Unfortunately there are no plans at this time to support these other
formats.

Hi Brenda.
How hard is this to do? If one of these drivers was done for QNX 4 it could
also be used for QNX 6 some some minor mods or vice-versa.
I’m sure other people want this and can make some noise!

Hi Augie,
If this is a major requirement for you, you can contact your sales
representative and see about custom engineering.

We use Pp.bmp and post-process the BMP with ‘cjpeg’ into a JPG file.
Pretty quick (at least ‘cjpeg’) 
See http://www.jpeg.org for details …

Hi Karsten,
Thanks for the tip. How did you get ‘cjpeg’? Did you have to become a
member? I didn’t find any source code for QNX 4 in the jpeg site.
BTW, How often are you printing and doing the conversion to jpeg?
We would like to do it for our documentation.
Our clients need to print Photon windows very often, durring the research
projects. They can print 50 or more windows in a 4 hour research flight.
At 25MB per bit map, this will be over 1GB of data just for the printing
output, never mind the acutal data.
Also this would add an extra process to getting the output and time is
limited during the research flights. Too many things to do and pay
attention to.
If you could use a driver to jpeg, please voice your concern.
Thanks
Augie

It was behind one of the links:

We use it in our web server applications, built on slinger and Photon
to reduce the size of graphics produced by certain photon
applications.
The package compiles right out-of-the-box and the utilties ‘cjpeg’
and ‘djpeg’, as well as a library work pretty well.
We also use the library to display JPGs from webcams, since the
Photon routines only work with files and the often die with SIGSEGVs.
We would like to do it for our documentation.

I think, ‘cjpeg’ is pretty quick, it compresses a 800x600 color bitmap
into a 70%-quality JPG in less than a second on a 266MHz machine.
Also this would add an extra process to getting the output and time is
limited during the research flights. Too many things to do and pay

Yes: a Pp.jpg (or any other of the drivers, quoted above)
would be a good idea!!
BTW: it not a big deal to create a JPG-file directly from a
PhImage_t-structure. The scanlines are almost compatible, since Photon
and the ‘libjpeg’ both use 24-bit RGB components for representing
single pixels, except that you have to swap the R and B parts since
Photon images are ordered Blue-Green-Red (the docs are wrong in this
point).
Best regards,
Karsten.
