Can you also send me the complete configuration you used ?
The setup:
Raspberry Pi 2 Model B
Raspbian Jessie (Debian version 8.0)
Lazarus 1.2.4+dfsg2-1 (It is the version available on their repository.
Call me lazy :)
fpc 2.6.4+dfsg-4+rpi1 (Again, it is the version available on their
repository.)
I have update the repository to include the Raspberry Pi example.
I would like to write an article for Blaise Pascal magazine, the editor
will
be very pleased to hear this, he has been asking for it since a long
time :)
Nice :)
The supplied example does not work out of the box because the gtk
based form viewer component isn't working with the raspberry pi. I had
to replace it with a bgrabitmap based one. That adds one more
dependency. Do you have any suggestion for a fpc "native" alternative?
You mean an image component ? What is missing in the ones in fpImage ?
When I was investigating fpImage, in the wiki
(ttp://wiki.freepascal.org/fcl-image) came across with this:
"fcl-image is written for maximal portability and maintainability and is
quite slow. The main storage type is 16-bit RGBA, storing always 64-bit
per pixel, and a function is called to get each pixel."
That does not seem good for showing a 640x480 image 30 times per second.
If the problem was only showing the image, the native overlay
capabilities could take of that, but usually we want to show also the
processed image.
For the bgrabitmap I need only to do a direct copy of the acquired
buffer to its internal storage.
