I'm using a wrapper of OpenAI gym to create a graphical representation of a problem. For that, I'm drawing a circle with the given wrapper and then try to add some text.
My issue is, that only the circle shows, but the text label does not appear. Any suggestions on how I can make the text visible would be highly appreciated. Below a minimal example, that show the problem:
import pyglet
from gym.envs.classic_control import rendering
screen_width = 600
screen_height = 400
table_radius = 200
viewer = rendering.Viewer(screen_width, screen_height + 20)
table = rendering.make_circle(radius=table_radius, filled=False)
table_trans = rendering.Transform()
table.add_attr(table_trans)
table_trans.set_translation(screen_width / 2, screen_height / 2)
viewer.add_geom(table)
text = 'This is a test but it is not visible'
label = pyglet.text.Label(text, font_size=36,
x=10, y=10, anchor_x='left', anchor_y='bottom',
color=(255, 123, 255, 255))
label.draw()
viewer.render(return_rgb_array=False)
input()
What worked for me is to manually implement the render function and insert the label after the tranform.disable()
## Content of the render function
glClearColor(1, 1, 1, 1)
self.viewer.window.clear()
self.viewer.window.switch_to()
self.viewer.window.dispatch_events()
self.viewer.transform.enable()
for geom in self.viewer.geoms:
geom.render()
for geom in self.viewer.onetime_geoms:
geom.render()
self.viewer.transform.disable()
# Text
label = pyglet.text.Label(
"Hello, world",
font_name="Times New Roman",
font_size=36,
x=100,
y=100,
anchor_x="center",
anchor_y="center",
color=(255, 0, 0, 255),
)
label.draw()
arr = None
...
please try this code:
import pyglet
from gym.envs.classic_control import rendering
class DrawText:
def __init__(self, label:pyglet.text.Label):
self.label=label
def render(self):
self.label.draw()
screen_width = 600
screen_height = 400
table_radius = 200
viewer = rendering.Viewer(screen_width, screen_height + 20)
table = rendering.make_circle(radius=table_radius, filled=False)
table_trans = rendering.Transform()
table.add_attr(table_trans)
table_trans.set_translation(screen_width / 2, screen_height / 2)
viewer.add_geom(table)
text = 'This is a test but it is not visible'
label = pyglet.text.Label(text, font_size=36,
x=10, y=10, anchor_x='left', anchor_y='bottom',
color=(255, 123, 255, 255))
label.draw()
viewer.add_geom(DrawText(label))
viewer.render(return_rgb_array=False)

I am using 'cz.adaptech.tesseract4android:tesseract4android:4.3.0' in my Android project.
Is it possible to get bounding box with text data like in example below?
(32, 24, 60, 17) Maitre
(100, 24, 82, 19) corbeau,
(191, 28, 29, 13) sur
(227, 28, 22, 12) un
(257, 24, 50, 17) arbre
(315, 24, 70, 21) perché,
(79, 49, 58, 17) Tenait
Official sample shows how to get plain text only, not boxes with text inside:
TessBaseAPI tess = getTessBaseAPI(path, context);
String text = tess.getUTF8Text();
To get bounding box with text use next code:
TessBaseAPI tess = new TessBaseAPI();
// Given path must contain subdirectory `tessdata` where are `*.traineddata` language files
String dataPath = context.getExternalFilesDir(null).getPath() + "/OCRme/";
// Initialize API for specified language (can be called multiple times during Tesseract lifetime)
if (!tess.init(dataPath, "eng", TessBaseAPI.OEM_TESSERACT_LSTM_COMBINED)) {
throw new IOException("Error initializing Tesseract (wrong data path or language)");
}
// Specify image and then recognize it and get result (can be called multiple times during Tesseract lifetime)
tess.setImage(bitmap);
tess.setPageSegMode(TessBaseAPI.PageSegMode.PSM_AUTO_OSD);
tess.getUTF8Text();
ResultIterator resultIterator = tess.getResultIterator();
List < Rect > boxes = new ArrayList < > ();
List < String > texts = new ArrayList < > ();
while (resultIterator.next(TessBaseAPI.PageIteratorLevel.RIL_WORD)) {
Rect rect = resultIterator.getBoundingRect(TessBaseAPI.PageIteratorLevel.RIL_WORD);
String text = resultIterator.getUTF8Text(TessBaseAPI.PageIteratorLevel.RIL_WORD);
boxes.add(rect);
texts.add(text);
}
I wanna create a QWidget with 2 button and 1 label where this widget will be connected with a database in PYQT6. Now 1st button will move to previous data and 2nd button will move to next data and in the label I'll show the save image in that particular img save in that selected column of that database.

In the code below, DrawRect1 and DrawRect2 represent a simplified version of functions that draw multiple shapes on screen.
I want to display some supplementary information if I hover over any of the drawn rectangles (similar to the way a tooltip works). But I need to generate that display information from a function rather than static definition.
Given I know the coords of the draw rectangle, can I either create another type of object with the same coords, or link a hover action to each drawnrectangle, so that I could call a function defined something like this ? :
EDIT: I guess I need a object I can bind a wx.EVT_ENTER_WINDOW event to, that I can create at the same time as dc.DrawRectangle ? Or can I bind this handler to the panel and use x,y position to try and match to a list of drawn rectangle coords ?
The closest thing I could find on SO was this old question, wxpython tooltip at specific coordinates but it wasn't a comprehensive answer.

A DC doesn't appear to support adding a tooltip, which is annoying, especially as the underlying wx widget appears to, as far as I can tell from the docs.
The best I can come up with at the moment, is to track the mouse movements but it is far from satisfactory and I suspect so limited that it might not be any help.
With those caveats made, I've supplied 3 options for the ToolTip like display. Namely, setting and unsetting the tooltip of the panel itself, a statusbar entry and a popup window.
Discard any you don't require.

Is there any way to vertically-align text using ColumnText? I am using iTextSharp
Chunk c = new Chunk(text, this.detailFont);
Phrase myText = new Phrase(c);
ct.SetSimpleColumn(myText, llx, lly, urx, ury, lineheight, Element.ALIGN_BOTTOM);
ct.Go();
My text appears at the top of the box I specify. I would like it to align with the bottom of the box.
as it is as it should be
|---------------| |---------------|
| some text | ---> | |
| | | some text |
|---------------| |---------------|
The answer of birwin is just not working. The ColumnText alignment is accept only horizontal alignments. And this is working till ColumnText text is in Text mode. When you call the ColumnText.AddElement the ColumnText switches to CompositMode and the Alignment has no effect.
If you really want to Vertical Alignment in ColumnText then you have to create a content which has aligned content and must add to ColumnText. Only the Table and Cell the correct object where vertical alignment has any effect.
So first we have to create a table, with one column and one cell. And set the size of the cell to same as column text size.
And second, this table must be added to ColumntText
Here is my code:
// create doc
var pdfDoc = new Document( PageSize.A4 );
var pdfWriter = PdfWriter.GetInstance( pdfDoc, new FileStream( Path.Combine( Path.GetTempPath(), "test.pdf" ), FileMode.Create ) );
pdfDoc.Open();
var canvas = pdfWriter.DirectContent;
canvas.SaveState();
canvas.Rectangle( 100, 100, 100, 100 );
canvas.SetRgbColorFill( 255, 128, 128 );
canvas.Fill();
canvas.RestoreState();
// create font
BaseFont bfTimes = BaseFont.CreateFont( BaseFont.TIMES_ROMAN, BaseFont.CP1252, false );
Font times = new Font( bfTimes, (float)10, Font.ITALIC, new BaseColor( (int)232434 ) );
Phrase myText = new Phrase( new Chunk( "Hello World", times ) );
ColumnText ct = new ColumnText( canvas );
/* wrong birwin code :
ct.SetSimpleColumn( myText, 100, 100, 200, 200, ct.Leading, Element.ALIGN_BOTTOM );
*/
// new working code: crreate a table
PdfPTable table = new PdfPTable( 1 );
table.SetWidths( new[] { 1 } );
table.WidthPercentage = 100;
table.AddCell( new PdfPCell( myText )
{
HorizontalAlignment = Element.ALIGN_RIGHT,
VerticalAlignment = Element.ALIGN_BOTTOM,
FixedHeight = 100
} );
ct.SetSimpleColumn( 100, 100, 200, 200 );
ct.AddElement( table );
ct.Go();
pdfDoc.Close();
The Solution:
Chunk c = new Chunk(text, this.detailFont);
Phrase myText = new Phrase(c);
ct.SetSimpleColumn(myText, llx, lly, urx, ury, lineheight, Element.ALIGN_BOTTOM);
ct.Go(true);
if (ct.LinesWritten == 1)
{
ury = ury - (this.rowheight);
}
ct.SetSimpleColumn(myText, llx, lly, urx, ury, lineheight, Element.ALIGN_BOTTOM);
ct.Go();
ct.Go(true) -- Apparently the "true" here indicates the ColumnText is created in "Simulation" mode. I was not aware of this mode before comments to my question were posted.
if (ct.LinesWritten == 1) checks the number of lines that were written. If only one line was written, I shrink the size of the upper-right-y corner of my rectangle.
ct.SetSimpleColumn(myText, llx, lly, urx, ury, lineheight, Element.ALIGN_BOTTOM); when I call this line the second time, the ury (upper-right-hand corner) location has been changed and the box is smaller.
ct.Go() - The second time I call this, I don't pass the "true" param so the second call is not simulation mode and writes the data to the document.

I sent the program to my other computer and it still gets the same error. When I remove the "gameDisplay" line, it tells me that there is an invalid syntax in "def game_intro():".
All help would be greatly appreciated.
It looks like you got one mismatched paranthese on line 74
Just remove the very first one on that line and your code should work just fine again..
