Still playing with noise until I get some circuits cooking..... for testing the python_grab.py utility for the RIGOL DS1054Z
Noise is beautiful .... (a least until my function generator arrives ...)
Note: Having trouble getting the RIGOL to generate anything but PNG and BMP image formats. Still working on this, converting BMP to JPG manually for loading.
Also, the image is still a bit corrupted (known bug) - in this case on the bottom where the channel indicators are.
I was wondering is there something out there for Solaris 7 for screen capture?
Also it would really help if there was some software out there that can record whats happens on the screen for like 10 seconds or how ever long I need it to.
I did a search but doesn't seem to be alot out there. (10 Replies)
We are using Solaris 10 for our Radiation Treatment Planning and need to create a simulation for our service engineers. I need a screen capture tool that can not only capture screens, but create movies of mouse movements (similar to Captivate). I have contacted Oracle and talked to several people... (2 Replies)

Hello everyone!

Sadly, I have turned off my access to the Apple Developers Beta program after installing macOS 10.15 Catalina a few days ago.
After the install, I rebooted by MacBook Air and it "hard froze" and we were heading out of town so I grabbed a backup MBA running Mojave.

Just a quick note for macOS users.
I just installed (and removed) Parallels Desktop 15 Edition on my MacPro (2013) with 64GB memory and 12-cores, which is running the latest version of macOS Catalina as of this post. The reason for this install was to test some RIGOL test gear software which... (6 Replies)

pfsoutimgmagick(1) General Commands Manual pfsoutimgmagick(1)NAME
pfsoutimgmagick - Write images or frames using Image Magick library
SYNOPSIS
pfsoutimgmagick [--linear] [--quality <val>] [--bit-depth] [--frames <range>]) <file> [<file>...]
DESCRIPTION
This command can write images or frames in the multitude of image formats supported by the ImageMagick library. This includes but is not
limited to: BMP, JPG, PNG, GIF, EPS, TIFF, DPX. See the manual page of ImageMagick for the full list of available formats.
pfsoutimgmagick reads images or frames in pfs format from the Standard Input and writes them under the specified file name(s).
The input of pfsinimgmagick must be within 0-1 range. If LUMINANCE tag set is set to RELATIVE or ABSOLUTE, the linear values will be gamma
corrected, assuming sRGB color space. Use --linear switch to disable gamma correction.
The images are stored using the bit-depth for which the ImageMagick library was compiled (default is 16 bit). Note that some formats (for
example JPEG) do not support encoding more than 8 bits per color channel. To use higher bit-depths, store images in the PNG format.
This command stores 'ALPHA' channel if it is present in the pfs stream.
Each file name can contain a %d pattern, which is substituted with frame numbers. The pattern has the same syntax as C printf command. For
example, you can use %04d to make the frame number four digit with proceedings zeros. You can select the frames using the following options
(the options must be always given after the file name):
--frames <range>
Range is given in mathlab / octave format:
startframe:step:endframe
Frame numbers start with startframe (default 0), are increased by step (default 1) and stop at endframe You can skip one of those
values, for example 1:100 for frames 1,2,...,100 and 0:2: for frame 0,2,4,... up to the last file that exists.
--srgb, -s
Apply the sRGB non-linearity (approximately 2.2 gamma) before writing a file. This can be used instead of using pfsgamma -g 2.2 to
store the result of some tone-mapping operators. The option will compress contrast to make sure that tone values are properly shown
on a display. It should be only used with linearized (not gamma corrected) images that are normalized to the 0-1 range.
--quality <val>, -q <val>
Set JPEG/PNG compression level from 1 to 100. Default 75.
--bit-depth <val>, -b <val>
Enforce bit-depth (per color channel). The allowed values are from 8 to 32. If not specified, the bit depth from the pfs stream
('BITDEPTH' tag) will be used instead. If the 'BITDEPTH' tag is missing, the ImageMagick default value will be used (usually 16).
The bit depth of actually stored file may be lower of that specified, if the file format does not support higher bit depths.
EXAMPLES
pfsin test.jpg | pfsout test.png
Convert from one image format to another.
pfsin --linear test.jpg | pfsout --srgb test.png
The same as above, but apply inverse gamma correction after reading an image (--linear) and then apply gamma correction before writ-
ing an image (--srgb).
BUGS
pfsoutimgmagick can not write frames to the standard output.
