I have this PowerShell code:
$AsyncTask = $BitmapDecoder.GetSoftwareBitmapAsync()
But discovered that some of the images coming in are rotated, so experimenting I came up with this:
$BmTf = [BitmapTransform]::new()
$BmTf.Rotation = [BitmapRotation]::None
# $BmTf.Rotation = [BitmapRotation]::Clockwise90Degrees
# $BmTf.Rotation = [BitmapRotation]::Clockwise180Degrees
# $BmTf.Rotation = [BitmapRotation]::Clockwise270Degrees
$AsyncTask = $BitmapDecoder.GetSoftwareBitmapAsync(
[BitmapPixelFormat]::Bgra8,
[BitmapAlphaMode]::Ignore,
$BmTf,
[ExifOrientationMode]::IgnoreExifOrientation,
[ColorManagementMode]::DoNotColorManage
)
While it does work, I'm not familiar BitmapPixelFormat, or the other parameters. The documentation for GetSoftwareBitmapAsync() doesn't appear to give any hints on what the default value it is using for BitmapPixelFormat.
Does anyone know the best values to pass to the version of GetSoftwareBitmapAsync() that takes 5 parameters to mimic the version of GetSoftwareBitmapAsync() that takes 0 parameters?
EDIT:
Just found out that trying [BitmapPixelFormat]::Unknown causes this error:
Exception calling "GetSoftwareBitmapAsync" with "5" argument(s): "The
parameter is incorrect. Windows.Graphics.Imaging: The bitmap pixel
format is unsupported."
But no errors with [BitmapPixelFormat]::Bgra8.
I don't know why GetSoftwareBitmapAsync doesn't like [BitmapPixelFormat]::Unknown, but here is the solution I found.
I need to first load the image to see if it needs rotating. That is done with the original command:
$AsyncTask = $BitmapDecoder.GetSoftwareBitmapAsync()
$SoftwareBitmap = GetAsync( $AsyncTask, ([SoftwareBitmap]) )
Then extract its BitmapPixelFormat:
$BitmapPixelFormat = $SoftwareBitmap.BitmapPixelFormat
And then use $BitmapPixelFormat for all calls to the 5 parameter version of GetSoftwareBitmapAsync().

I'm trying to create new vector layer with the same fields as contained in original layer.
original_layer_fields_list = original_layer.fields().toList()
new_layer = QgsVectorLayer("Point", "new_layer", "memory")
pr = new_layer.dataProvider()
However, when I try:
for fld in original_layer_fields_list:
type_name = fld.typeName()
pr.addAttributes([QgsField(name = fld.name(), typeName = type_name)])
new_layer.updateFields()
QgsProject.instance().addMapLayer(new_layer)
I get a layer with no fields in attribute table.
If I try something like:
for fld in original_layer_fields_list:
if fld.type() == 2:
pr.addAttributes([QgsField(name = fld.name(), type = QVariant.Int)])
new_layer.updateFields()
QgsProject.instance().addMapLayer(new_layer)
... it works like charm.
Anyway ... I'd rather like the first solution to work in case if one wants to automate the process and not check for every field type and then find an appropriate code. Besides - I really am not able to find any documentation about codes for data types. I managed to find this post https://gis.stackexchange.com/questions/353975/get-only-fields-with-datatype-int-in-pyqgis where in comments Kadir pointed on this sourcecode (https://codebrowser.dev/qt5/qtbase/src/corelib/kernel/qvariant.h.html#QVariant::Type).
I'd really be thankful for any kind of direction.
I was trying to make a tween for a text so whenever when player loaded and wait for at least 5 seconds after they loaded in, the text transparency will set to 0 smoothly
Then, I tried to make that happen with a service called TweenService but I was greeted with an error "Unable to cast to Dictionary"
I tried another way by checking the documentation and Forums but didn't find or solve any solutions
Here's my code:
local loadingrobloxos = LoadingAssetsGUI.LoadingBootBackground.LoadingRobloxOS
local goallro = loadingrobloxos.TextTransparency == 0
local tweeninfolro = TweenInfo.new(
0.5,
Enum.EasingStyle.Quad,
Enum.EasingDirection.InOut,
1,
false
)
local tweenlro = TweenService:Create(loadingrobloxos, tweeninfolro, goallro):Play()
What is actually wrong?
If you look at the documentation for TweenService:Create, you'll see that the last argument of the function is supposed to be a dictionary.
TweenService:Create(loadingrobloxos, tweeninfolro, goallro)
The error is telling you that whatever you passed in for the variable goallro, it cannot be converted to a dictionary. And that line is...
local goallro = loadingrobloxos.TextTransparency == 0
This line is not creating a dictionary, it is asking the question, "is loadingrobloxos's TextTransparency currently set to zero?" So the variable goallro is set to false. TweenService doesn't know what to do with false, so it throws the error.
Instead, try this :
local goallro = {
TextTransparency = 0
}
I am using this snippet in order to create a mf4 file with a value to text table, found in the examples from asammdf's github.
vals = 5
conversion = {
'val_{}'.format(i): i
for i in range(vals)
}
conversion.update(
{
'text_{}'.format(i): 'key_{}'.format(i).encode('ascii')
for i in range(vals)
}
)
sig = Signal(
np.arange(cycles, dtype=np.uint32) % 30,
t,
name='Channel_value_to_text',
conversion=conversion,
comment='Value to text channel',
)
sigs.append(sig)
mdf.append(sigs, comment='arrays', common_timebase=True)
Is there a way to create a table with ##TX blocks and also ##CC blocks?(in order to simulate a scale conversion)
Thank you!
If anyone needs it, I found the answer and it was simpler than expected.
Create another conversion (i.e conversion2) in the same manner as the first one, then reassign the value of one of the references to it.
conversionBlock = from_dict(conversion)
conversionBlock.referenced_blocks["text_4"] = from_dict(conversion2)
I am having a model which takes two input & multiplies them & give the output.
output_1 = input_1 * input_2
I have declared my simulink signals as CustomStorageClass= GetSet
input_1 = Simulink.Signal;
input_1.CoderInfo.StorageClass = 'Custom';
input_1.CoderInfo.CustomStorageClass = 'GetSet';
input_1.CoderInfo.CustomAttributes.GetFunction = 'Get_input_1';
input_1.CoderInfo.CustomAttributes.SetFunction = 'Set_input_1';
input_1.CoderInfo.CustomAttributes.HeaderFile = 'signals.h';
input_2 = Simulink.Signal;
input_2.CoderInfo.StorageClass = 'Custom';
input_2.CoderInfo.CustomStorageClass = 'GetSet';
input_2.CoderInfo.CustomAttributes.GetFunction = 'Get_input_2';
input_2.CoderInfo.CustomAttributes.SetFunction = 'Set_input_2';
input_2.CoderInfo.CustomAttributes.HeaderFile = 'signals.h';
output_1 = Simulink.Signal;
output_1.CoderInfo.StorageClass = 'Custom';
output_1.CoderInfo.CustomStorageClass = 'GetSet';
output_1.CoderInfo.CustomAttributes.GetFunction = 'Get_output_1';
output_1.CoderInfo.CustomAttributes.SetFunction = 'Set_output_1';
output_1.CoderInfo.CustomAttributes.HeaderFile = 'signals.h';
Now I am trying to convert my model to code using simulink coder.
In code generation setting of the model i have selected ert.tlc file in the system target file settings.
But the generated code does not have a Get_input_1() or Get_input_2() call like shown in this link.
http://www.mathworks.com/help/ecoder/ug/getset-custom-storage-classes.html
What i have missed in the setting. Please suggest
I know you probably already solved this issue, but I have also seen this behavior before.
Sometimes MATLAB does not update the header files correctly. If you had set a different configuration for your variable and then made a change involving the header files, I would recommend erasing the *_ert_rtw and slprj folders (they will appear again). It is similar to doing a "Make clean" operation, to ensure that everything is brand new.
I've got this odd problem.
If I make a call on that function through amfphp service browser and give it a valid ID and leave the $num_images field blank amfphp will actually pass a blank string as the argument.
// if i call this function width just an ID
function getWorkers($id, $num_images = 100) {
...
// num_images will be set as ''
}
I can easily override using a check:
function getWorkers($id, $num_images = 100) {
if($num_images=='') $num_images = 100;
...
// num_images will now be really set as 100
}
Anyone experiencing the same with amfphp?
That's odd, I never got that from AMFPHP. If you don't have the latest version try updating your installation of AMFPHP. Also make sure Flash doesn't somehow pass an empty variable as the second variable.
