As the title indicates, I am looking at creating a label for a player Gui in Roblox using only code. Under the folder StarterGui, I have a ScreenGui, and as a child of ScreenGui I have a local script with the following code:
local ScreenGui = script.Parent
local label = Instance.new("TextLabel", ScreenGui)
label.Size = UDim2.new({0, 200},{0, 100})
label.Text = "label"
label.TextColor3 = Color3.new (0,0,0)
label.TextSize = 36
label.Font = "Arial"
label.TextScaled = true
I am pretty sure I should be seeing a label with the word ''label'' by now, but nothing. What am I missing?
The line that says
label.Size = UDim2.new({0, 200},{0, 100})
Should be
label.Size = UDim2.new(0, 200, 0, 100)
This is because UDim2.new accepts 4 arguments, not 2 arrays.
Hope I could help!
I'm running python3.6 with openCV on the Raspberry pi(OS is Raspbian)
The approximate structure of the code is as follows.
The image is captured at time interval(3~5 min).
Captured image is processed in functions and returns measure(kind of accuracy)
Iterate 1.~2. until end_check() returns True
Problem is that the most recent taken image is out of date. It looks it was taken almost 10 minutes ago. All images recently taken are late. But the images taken at the beginning seem to be timed. And the time recorded in all .jpg files entered correctly
+It looks this problem is occured after more than a hour. (20~22 iterates)
Images are captured with cam0.read() in the cv2 package. Below is main part of the code. It is quite long to upload full code. It someone request, I will update.
def run(interval,model_list):
cam0 = cv2.VideoCapture(0) #Only cam0 is used. cam2 is just to record.
camdir = "/home/pi/capstone/cam0/"
cam2 = cv2.VideoCapture(1)
cam2dir = "/home/pi/capstone/cam2/"
runNo = 0
acc_list = list()
error_list = list()
end = False
while(end == False):
print(runNo,"th run")
img_name = "%s.jpg" %runNo
frame, res = cam0.read() #`res` is the image which will be processed
cv2.imwrite(os.path.join(camdir,img_name),res)
_ , cam2pic = cam2.read()
cv2.imwrite(os.path.join(cam2dir,img_name),cam2pic)
try:
temp = Real(res)
mat = temp.match(model_list)
acc_list.append([mat,runNo])
print("Accuracy=", mat)
except ValueError:
acc_list.append(["ValueError",runNo])
error_list.append(["ValueError",runNo])
except AttributeError:
acc_list.append(["AttributeError", runNo])
error_list.append(["AttributeError",runNo])
except SmallObjectError:
acc_list.append(["SmallObjectError", runNo])
error_list.append(["SmallObjectError",runNo])
runNo = runNo+1
endNo = 40
if(runNo/2 > endNo):
end_check(res, end)
elif(runNo > endNo):
end = True
sleep(interval*60)
with open("acc_list.txt", "w") as output: #records for tracking errors
output.write(str(acc_list))
with open("err_list.txt", "w") as output:
output.write(str(error_list))
cam0.release()
cam2.release()
run(3.5,model_list)
(+) Some newly found things and guess
The images time gap is getting bigger with code running
Code finally showed OpenCV Error
It looks kind of Video signal is stored in RAM on R-pi and .read() returning out-dated image in RAM
Stored Video signal in RAM araise resource problem
Below is the OpenCV Error
OpenCV Error: Assertion failed (dsize.area() > 0 || (inv_scale_x > 0 && inv_scale_y > 0)) in resize, file /home/pi/opencv/opencv-3.4.0/modules/imgproc/src/resize.cpp, line 4045

(+) Some part of code araising Error
This is __.resize() method. When I process the image that occured OpenCV Error manually, it works well even if OpenCV Error pointing out kind of image size matter. So I thought it is not matter of image itself or size got from md_inf(). Anyway Here is code.
def __resize(self, md_inf):
#md_inf = [219, 122, 132, 171, 262] <-sample
reratio = md_inf[0]/self.y
if(reratio>1):
inter_method = cv2.INTER_LINEAR
else:
inter_method = cv2.INTER_AREA
###below is line 147###
self.mask = cv2.resize(self.mask, None, fx=reratio, fy=reratio, interpolation = inter_method)
temp = np.zeros((md_inf[3], md_inf[4]), np.uint8)
m_cx, m_cy = md_inf[1:3]
_, contour, _ = cv2.findContours(self.mask, cv2.RETR_EXTERNAL,cv2.CHAIN_APPROX_SIMPLE)
total_contour = contour[0]
for ctr in contour[1:]:
total_contour = np.concatenate((total_contour, ctr), axis =0)
mmt = cv2.moments(total_contour)
if(mmt['m00'] < 7500):
raise SmallObjectError
self.cy = int(mmt['m10']/mmt['m00']) #y is horrizon axis
self.cx = int(mmt['m01']/mmt['m00']) #x is vertical axis
x, y = self.mask.shape
adjust = m_cx - self.cx + x - temp.shape[0]
if(adjust > 0):
m_cx = m_cx - adjust
temp[(m_cx-self.cx):(m_cx-self.cx) +x, (m_cy-self.cy):(m_cy-self.cy) +y] = self.mask
self.mask = temp
I agree with Mark Serchell's comment. The way I am using is to set variable to time + x seconds and check. OpenCV have useful feature for skiping frames like cam.grab(). It will just read that frame from buffer but will not do anything with it. In that way you can avoid "suffering from buffering". Simple code would be:
import cv2
import time
cam = cv2.VideoCapture(url)
ret,frame = cam.read()
timeCheck = time.time()
future = 10*60 # delay
while ret:
if time.time() >= timeCheck:
ret,frame = cam.read()
# Do your staff here
timeCheck = time.time()+future
else:
# Read from buffer, but skip it
ret = cam.grab() # note that grab() function returnt only status code,not the frame
Hello!
i'm trying to have my images appearing on a label by using this code
this is to save a random image from a particular URL
def photo_1():
urls = "https://www.flickr.com/photos/flickr/galleries/72157644537473411/" # You may change this into other websites!
regex = '<img src="([^"]+)".*>'
pattern = re.compile(regex)
photofile=urllib.urlopen(urls)
raw_data=photofile.read()
download=re.findall(pattern,raw_data)
randomdownload=random.choice(download)
urllib.urlretrieve(randomdownload, "1.gif")
global done_button2
done_button2 = Button(photo_window, text = 'Click here to display your chosen image on the black screen!', width = 53, command = generate_1)
done_button2.grid(row = 5, sticky = N)
done_button.config(state='disabled')
and this is to have the saved image appearing on a label but apparently not working so well ..
def generate_1():
img = ImageTk.PhotoImage(Image.open("1.gif"))
image_area = Label(photo_window, image = img, width = 55, height = 5).grid(row=2)
global done_button3
done_button3 = Button(photo_window, text = 'Click here to save the second random image locally! ', width = 53, command = photo_2)
done_button3.grid(row = 6, sticky = N)
done_button2.config(state='disabled')
this was a part of my code and when i run this application i made,
the only thing i can see is a white rectangular shape and i would like it to be as big as a black label underneath (size of (55,5) )with the actual image appearing...
can anyone help me with this problem?
You might have thought that my English is not that great haha
but please have mercy!
In one case i am rendering all images from all news entries from one specific category inside an unordered list. Each image is wrapped inside an anchor element which itself is wrapped inside a list-item. Each image is 100% white and shall be displayed transparent.
After solving a few transparency related issues i now stand before the problem that ALL images are given an outline which i am not aiming for - since in some cases it might clash with the background (the background Image is changing sometimes). Either i have something missing in my code or something is wrong with the images i am trying to use.
Here is the typoscript code used for rendering the images:
myMarker.20 < plugin.tt_news
myMarker.20
{
code >
code = LIST
templateFile = fileadmin/templates/ext/tt_news/myMarker_template.html
excludeAlreadyDisplayedNews = 0
limit = 6
categoryMode = 1
categorySelection = 5
catImageMode = 0
catTextMode = 1
listOrderBy = title asc
displayList
{
image >
image.stdWrap.cObject = IMAGE
image.stdWrap.cObject.linkWrap = |
image.stdWrap.cObject.linkWrap.insertData = 1
image.stdWrap.cObject.titleText.field = title
image.stdWrap.cObject.file = field:image
image.stdWrap.cObject.file = GIFBUILDER
image.stdWrap.cObject.file
{
format = png
XY = 130, 48
transparentBackground = 1
backColor = transparent
10 = IMAGE
10
{
offset = 0, 48-[10.h]/2
border = 0
file
{
import = uploads/pics/
import.data = field:image
import.listNum = 0
import.override.field = image
maxW = 130
maxH = 48
quality = 100
}
}
}
}
} # myMarker
Maybe someone has an idea? Thanks for reading/help in advance anyway :)
Solved by not using gifbuilder.
Good day all! I have a very tricky for me question.
In my application I have button with image inside. All properties of this button:
Me.cmdSelectAll.BackColor = System.Drawing.SystemColors.Control
Me.cmdSelectAll.Image = CType(resources.GetObject("cmdSelectAll.BackgroundImage"), System.Drawing.Image)
Me.cmdSelectAll.ImageAlign = Drawing.ContentAlignment.BottomRight
Me.cmdSelectAll.Cursor = System.Windows.Forms.Cursors.Default
Me.cmdSelectAll.Font = New System.Drawing.Font("Arial", 8.0!, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, CType(0, Byte))
Me.cmdSelectAll.ForeColor = System.Drawing.SystemColors.ControlText
Me.cmdSelectAll.Location = New System.Drawing.Point(0, 282)
Me.cmdSelectAll.Name = "cmdSelectAll"
Me.cmdSelectAll.Padding = New System.Windows.Forms.Padding(0, 0, 0, 0)
Me.cmdSelectAll.RightToLeft = System.Windows.Forms.RightToLeft.No
Me.cmdSelectAll.Size = New System.Drawing.Size(22, 22)
Me.cmdSelectAll.TabIndex = 11
Me.cmdSelectAll.TabStop = False
Me.ToolTip1.SetToolTip(Me.cmdSelectAll, "Select All Channels")
Me.cmdSelectAll.UseVisualStyleBackColor = False
When I run it with default text size of win7, the image appears in the center, it's all ok. But when I set some custom value of text size (115%) my image suddenly goes more right and down. It occurs with all of my button's images. Could you please answer me why does this happen and how can i fix this issue? Thanks
