How do I place a textclip, right below the other? I require to place an image at the left of the video and two lines of text to the right of image, that are placed one below the other.
Something like this:
I tried to use set_position, but doesn't scale well for different videos (of different resolutions). By adjusting the arguments of set_position, I am able to place the textclips one below the other without gap in one resolution, but when I go to a higher resolution video, it shows a gap (I understand why the gap comes, but not sure how to prevent it)
txt_clip1 = TextClip("This is line 1 of text", fontsize = 12, color = 'white', bg_color='black')
txt_clip1 = txt_clip1.set_duration(7).set_start(0).set_end(7)
txt_clip1 = txt_clip1.set_position((0.1,0.90), relative=True).set_opacity(0.6)
txt_clip2 = TextClip("This is line 2 of the text, smaller font", fontsize = 8, color = 'white', bg_color='black')
txt_clip2 = txt_clip2.set_duration(7).set_start(0).set_end(7)
txt_clip2 = txt_clip2.set_position((0.1,0.93), relative=True).set_opacity(0.6)
I tried to insert a new line character in the text, but that doesn't suit me because the second line of text has different font properties.
Hopefully this will help you
txt_clip1 = TextClip(
"Cool effect 2nd line", color="black", bg_color="red", font="Amiri-Bold", kerning=5, fontsize=20
)
cvc = CompositeVideoClip([txt_clip1.set_position("East")], size=screensize)
txt_clip1 = txt_clip1.set_position((5,35))
.set_position mother take to arguments 1st is the position from the left screen and second is the position from the top
so your code is like something
txt_clip1 = txt_clip1.set_position((5,500))
txt_clip2 = txt_clip2.set_position((5,535))
It will place the text in the position you want.
Hopefully, this will help.
Happy coding

drawing a line a positioning int
I have a document where I want the following
From b = to x
Text1-->Image -->line--> Text2
Where line is between image1 and before Text2
Next b
It would look like "SomeText1" image Line "-------" "SomeText2"
Where ------ is a solid line, and every line has these 4 elements all on the same Y
I'm using
Y = Doc.GetRenderer().GetCurrentArea().GetBBox().GetTop()
To get and hold the Y position as I build up the b position as I drop in the text and image.
Using
new line = new SolidLine(1f)
dim ls = new LineSeparator(line)
It's the placing of the line I'm having trouble with.
setMarginTop doesn't work for obvious reasons and SetFixedPosition doesn't seem to work
To summarize: The text and image are fine and placed at the correct Y spot, but I'm unable to place the line on the same Y part of the page as the text and image. I've looked at using Canvas, but the samples seem to suggest I need to add a new page.
Any help much appreciated
In iText 7.1.9 I am taking a pdf created programmatically (not via iText) and need to apply a transparent rectangle along the left side and bottom to ensure the no content exists within a predefined clear zone (for print).
The below code places the yellow rectangles correctly but the desired result is the for the yellow fill to be semi-transparent or not 100% opaque so that visual inspection will show the content that that intersects with the rectangle instead of the rectangle clipping the content.
var page = pdf.GetPage(1);
PdfCanvas canvas = new PdfCanvas(page);
canvas.SaveState();
canvas.SetFillColor(iText.Kernel.Colors.ColorConstants.YELLOW);
var pageHeight = page.GetPageSize().GetHeight();
var pageWidth = page.GetPageSize().GetWidth();
// left side
canvas.Rectangle(0, 0, 15, pageHeight);
// bottom
canvas.Rectangle(0, 0, pageWidth, 15);
canvas.Fill();
canvas.RestoreState();
I attempted to use a TransparentColor but canvas.SetFillColor won't accept a TransparentColor, are there any other options?
When we speak about low-level content stream instructions, color itself and transparency levels are specified separately in PDF syntax. The TransparentColor class that you speak about was designed to simplify lives of users who are less familiar with nuances of PDF syntax, but it it a higher-level class that you can use e.g. in layout module, and in your case you operate with the document on quite low level.
Long story short, to set color transparency you only need one additional line next to setting the color itself:
canvas.SetExtGState(new PdfExtGState().SetFillOpacity(0.5f));
So the code becomes:
var page = pdf.GetPage(1);
PdfCanvas canvas = new PdfCanvas(page);
canvas.SaveState();
canvas.SetFillColor(iText.Kernel.Colors.ColorConstants.YELLOW);
canvas.SetExtGState(new PdfExtGState().SetFillOpacity(0.5f));
var pageHeight = page.GetPageSize().GetHeight();
var pageWidth = page.GetPageSize().GetWidth();
// left side
canvas.Rectangle(0, 0, 15, pageHeight);
// bottom
canvas.Rectangle(0, 0, pageWidth, 15);
canvas.Fill();
canvas.RestoreState();
I have been trying to adjust the position of labels in Mapview. However, the functions that I have seen discussed won't work for me. The one that comes closest so far is addStaticLabels.
library(mapview)
mapview(breweries) %>% addStaticLabels(label = breweries$zipcode,
direction = 'left',
offset = c(12,-15),
textsize = "10px")
No matter what offset I give it doesn't change where the text is. This makes it really hard to see the text and the point.
I have these two functions in my program:
def depict_ph_increase(x,y,color, imobject):
program_print(color)
draw = PIL.ImageDraw.Draw(imobject)
draw.text((x, y),color,(255,255,255))
imobject.save('tmp-out.gif')
im_temp = PIL.Image.open("tmp-out.gif")#.convert2byte()
im_temp = im_temp.resize((930, 340), PIL.Image.ANTIALIAS)
MAP_temp = ImageTk.PhotoImage(im_temp)
map_display_temp = Label(main, image=MAP_temp)
map_display_temp.image = MAP_temp # keep a reference!
map_display_temp.grid(row=4,column=2, columnspan=3)
def read_temp_pixels(temperature_file, rngup, rngdown):
temp_image_object = PIL.Image.open(temperature_file)
(length, width) = get_image_size(temp_image_object)
(rngxleft, rngxright) = rngup
(rngyup,rngydown) = rngdown
print 'the length and width is'
print length, width
hotspots = 5;
for hotspot in range(0,hotspots):
color = "#ffffff"
while color == "#ffffff" or color == "#000000" or color == "#505050" or color == "#969696":
yc = random.randint(rngxleft, rngxright)
xc = random.randint(rngyup,rngydown)
color = convert_RGB_HEX(get_pixel_color(temp_image_object, xc, yc))
depict_ph_increase(xc,yc,color, temp_image_object)
The bottom one calls the top one. Their job is to read in this image:
It then randomly selects a few pixels, grabs their colors, and writes the hex values of the colors on top. But, when it redisplays the image, it gives me this garbage:
Those white numbers up near the upper right corner are the hex values its drawing. Its somehow reading the values from the corrupted image, despite the fact that I don't collect the values until AFTER I actually call the ImageDraw() method. Can someone explain to me why it is corrupting the image?
Some background--the get_pixel_color() function is used several other times in the program and is highly accurate, its just reading the pixel data from the newly corrupted image somehow. Furthermore, I do similar image reading (but not writing) at other points in my code.
If there is anything I can clarify, or any other part of my code you want to see, please let me know. You can also view the program in its entirety at my github here: https://github.com/jrfarah/coral/blob/master/src/realtime.py It should be commit #29.
Other SO questions I have examined, to no avail: Corrupted image is being saved with PIL
Any help would be greatly appreciated!
I fixed the problem by editing this line:
temp_image_object = PIL.Image.open(temperature_file)
to be
temp_image_object = PIL.Image.open(temperature_file).convert('RGB')
I'm trying to add line dividers between views. However, there is a forced margin on every element I try (Image, BoxView, Frame, Label). I set the margin to be 0, the HeightRequest is always 3, but as you can see the view bounds expand past the actual view. Is there a specific view I'm supposed to be using? I just want the gray line and nothing more.
var line2 = new Frame
{
WidthRequest = (App.ScreenDpWidth / 2),
MinimumHeightRequest = 3,
HeightRequest = 3,
BackgroundColor = Color.FromHex("#229EBB"),
Margin = new Thickness(0, 0)
};
I assume you are layouting your elements either in a Grid or a StackLayout.
By default, the StackLayout.Spacing, Grid.RowSpacing and Grid.ColumnSpacing properties are set to 6d.
Without more information, I think that's what you're seeing in your code. Change those values to 0d.
Also, if you only want a gray line, you can use a BoxView which will draw a gray box, and set it's Height to 1d.
