Is it possible to round the corners of a rectangle in rdlc Report?
I'm trying to make an oval frame in which will be some parameter with text.
I don't think anything changed in that area since, but here is what I found when I was looking for similar feature: Rounded corners on report body and header borders. I think background image is your only option and you can create it dynamically too.
Also, here is the another suggestion: from SO, but I haven't tried that approach, so don't know if it works.

I have a png that's size 150x100 , and I set the UI image to the same, but it makes a bunch of extra space around it (that can be interacted with). How do I fix this?

Unity isn't adding extra space. The image itself HAS that space.
There are options to crop out the alpha space in Unity by using the sprite editor, but by my experience i prefer using a proper Image editor like Gimp. using one is the best way to handle your image assets.
To crop out the extra space you just have to reduce the canvas size.
Well, first you could check (in Unity) wether your Image has its property Preserve Aspect set to True.
You could click Set Native Size which is right below it, so the 'box' around your image will take it's size.
Edit: Nevermind the first two. I do not know why i thought they could solve it, i looked at your image again and i, too, think there are transparent pixels above and below it. So you should try this:
Then you could check whether your picture has any transparent pixels around it, using an image editor. If it has, you would need to cut them out.
I am using latest version of Debenu Quick PDF Library.
Is it possible to calculate the height of DrawHTMLText before drawing it on document?
I need it because, I want my application to decide where (x,y coordinates) to draw DrawHTMLText according to its dimensions.
For example if it exceeds document border from the bottom side I want it to pull it up to make it fit.
Thank you.
user3253797,
You can use the GetHTMLTextHeight function to determine the height before calling DrawHTMLText.
http://www.debenu.com/docs/pdf_library_reference/GetHTMLTextHeight.php
Note : DrawHTMLText will return any overflow text as a string that will not fit into the specified area. GetHTMLTextHeight should in theory return the text height for the text that can fit inside the box. If the text is too long to fit inside the one box then it sounds like you will need to modify the x,y positions and possibly the HTML text itself to make it all fit on one page.
Good luck.
Andrew.
Background
I want to be able to get the drawn dimensions of a zoomed image inside the picturebox (I'll explain below).
The PictureBox.ImageRectangle property seems to be exactly what I'm looking for because it shows the height and width of the resized image, as well as it's relative top, left position inside the control.
The trouble is PictureBox.ImageRectangle is private and so I can't read the values without using reflection (which is obviously not ideal).
Actual Question
My question is, is there another way that I can easily get to these values without writing a method to calculate what the values "ought" to be? I can do that easily enough, but I feel I'd be reinventing the wheel.
Context:
I'm writing a simple image processing app in C# and one of the things it has to do is allow the user to draw a selection around a portion of the image (a lot like the Marquee tool in Photoshop).
I need to know the dimensions of the rendered image so I know where to set the bounds of my marquee tool and also to translate the values of the drawn rectangle to points on the scaled bitmap inside the control.
My answer look simple so maybe I'm missing something, but I think Control.DisplayRectangle suits your need.
EDIT
OK, missed the point; however see How to get the value of non- public members of picturebox?
if you want to access dimension of the image in picture box you can use
GraphicsUnit units = GraphicsUnit.Point;
RectangleF imgRectangleF = pictureBox1.Image.GetBounds(ref units);
Rectangle imgRectangle = Rectangle.Round(imgRectangleF);
i will need to print an "x" according to the coordinates given to me from one of the tables in my database. im probably gonig to use c# to connect to mysql.
i will probably have a winform that is 8.5 x 11 inches (The size of a regular sheet of paper) and i will populate the entire thing with labels of "x" and they will be invisible.
each individual table record will have the coordinates of those labels which should NOT be invisible
the form for every record will show and will print. the printing will be on top of a paper that is actually a physical application itself.
the problem:
how to fill out a physical application using data from a mysql database. (dont tell me that i should be printing the entire app from scratch, the reason this is not possible is because the form is actually TRIPLE paper width (white, yellow, and pink copy), so i cannot print the entire app from scratch, i have to print on top of it.
the question: how do i print "x" at specified regions? is my solution the best way to go or is there a smarter approach?
in case you have no idea what i am talking about, here are some related questions:
ms-access: designing a report: printing text on specific x,y coordinates
Conditional formatting in Access
While labels would offer you the ability to make an X show up I don't feel that having a bunch of hidden labels is the best way.
Does the "application" represent some kind of form? Are you looking to "check-off" boxes using x's and then print this?
I may suggest using GDI+ (drawing) vs using labels.
Consider the following:
Locate the coordinates for your boxes. Then use the drawstring method within an overridden onPaint event-handler for your form or for the panel which may represent your form's canvas.
This article talks about GDI+ and how to draw text as graphics.

In normal C# it is easy to draw to a bitmap using the Grpahics.DrawString() method. Silverlight seems to have done away with Bitmap objects and Graphics is no longer available either. So...How am I meant to manipulate/create a bitmap when using Silverlight? If it helps, I am using Silverlight 3.
Let me tell you what I am doing. I am being given a template, basically a pre-rendered image. The user is then able to select from multiple images and enter the deisred text. I then render it to the image, adjusting size etc... within bounds and centering it in the pre-defined area of the image. If I can calculate the size (as in the MeasureString method) and then draw the string (as in the Graphics.DrawString method) that would be fine. The real question, no matter why I want to be able to do this, is can it be done?
The question is: why do you want to? Why not just use a TextBlock?
If you are trying to dynamically generate an image, use standard Silverlight/WPF controls (including TextBlock) and render them to a WritableBitmap.
Edit:
Ok, you've updated and expanded, which gives me more to go on. Unfortunately, you're not going to like the answer. First, keep in mind that Silverlight and WPF in general are vector based, and intended to be used as such. Although the Canvas allows you to do pseudo-pixel manipulations, you cannot be nearly as pixel-accurate as old-school GDI. This is a factor of your medium. If you absolutely have to measure things the way you want to measure them, I suggest you build your images on a remote server and transmit them to your Silverlight app.
You can calculate the size on-screen of the text rendered via a TextBlock using the ActualWidth and ActualHeight properties. But it only works on an already rendered control. Something like MeasureString is simply not available in Silverlight. Based on your description of your app, some user interaction could accomplish what you want. The user selects the image, enters the text, and is shown a preview. The user can then adjust the width and height of the various text areas until satisfied, at which point you can take a snapshot using the render method I liked to above.
The following may work, its a bit nebulous because I haven't tried yet myself.
The object you are looking for is the WritableBitmap.
You create a Visual tree, for example create your self a Grid or Canvas (you're not adding this to the UI). Add to it the selected image and a TextBlock positioned and sized as you prefer.
Create a new WritableBitmap either of a specific size or using the selected image to initialize it.
Use the WritableBitmap Render method passing the above root Grid or Canvas to it.
Now you have a bitmap which you should able to use to do whatever its you needed to do that required all this hoop jumping in the first place.
