I have an instance where I have a logo image as part of some artwork..If a user uploads a new logo I have a form field which is larger than the default logo.I then use that form field to position the new image.
The problem is I need to set the background colour of that form field to white so that it covers the old logo in the event that the new image is smaller than the old logo..
what I have done is:foreach (var imageField in imageReplacements)
{
fields.SetFieldProperty(imageField.Key, "bgcolor", iTextSharp.text.Color.WHITE, null);
fields.RegenerateField(imageField.Key);
PdfContentByte overContent = stamper.GetOverContent(imageField.Value.PageNumber);
float[] logoArea = fields.GetFieldPositions(imageField.Key);
[Code]...
The problem with this is that the background colour of the field is set to white and the image then doesn't appear.. i remove the SetFieldProperty and RegenerateField commands and the image replacement works fine.is there a way to set a stacking order on layers?
I have created a PNG image that is 200 DPI, and perfectly sized for a landscape A4 page size. I needed to convert this to a PDF document, so I've used the iTextSharp library with the code below.This all works, however the image quality has degraded.
Public Sub ConvertPNGtoPDF(ByVal inputFile As String, ByVal outputFile As String) Using fs As New FileStream(outputFile, FileMode.Create, FileAccess.ReadWrite, FileShare.None) Dim document As New Document(PageSize.A4.Rotate, 0, 0, 0, 0)
i need to add a data table right after an image on a PDF in vb.net
[Code]...
i highlighted broccoli, buckwheat, butter, cabbage. these are all part of a data table that is supposed to go after the bottom SEVERE word because the entire thing that you see is one image called jpg2
the user will pick an image on their hardrive and i will put it on a pdf file using itextsharp with vb.net. how do i manually set the dimensions of the picture?
I'm using iTextSharp to print a PDF document. Everything goes ok until I have to print the company logo in it. First I noticed that the logo had poor quality, but after testing with several images, I realize that was the iTextSharp rendering it poorly.The test I did to say this was to print the PDF using my code and then edit the document with Acrobat 8.0 and I drew an image. Then printed the two documents and saw the noticeable difference.My question is that if anyone know if this can be due to a scaling problem where I'm failing to tell iTextSharp how it must render the image or is an iTextSharp limitation.
I am placing and image using this [code]It works perfectly however when my document is extended to second or third page.. it does not stays on the first page.. it stays on same position however moves to the last page
I am using Stanav's PdfManipulation2.AddImageToPage(..., Pages) for iTextSharp library (v5.1.3) and was not able to add the image to specific pages: e.g. to add to only page 1 and 3 of a five pages PDF
Dim Pages() As Integer Pages = New Integer() {1, 3} PdfManipulation2.AddImageToPage(..., Pages)
Calling AddImageToPage() with the the optional Pages parameter will add the image to all pages though.
I have a picturebox in a Windows VB.NET form (not web based). I will be placing images into it from an image control. (Not a problem) I need to paint graphically a tiny solid circle (a colored circle) in a location (varies) on top of this picturebox. I am not finding how to do this in your indexes. I would some instruction on how to do this.
I have a form with some text boxes bound to a dataset using the binding source component I'd like to change one of the unbound fields in the current record programmatically before posting any changes from the bound controls
I have connected a serial tilt sensor to the PC,The sensor returns angle of tilt ,i need to represent the angle of tilt pictorially,When i move sensor the corresponding movement should be represented in a graph (Like a clock minute hand)For this i started with Picture box with back ground image,But when i draw the line according to tilt ,the line is not getting displayed on top of Picturebox,
I'm working on a UserControl which has two PictureBoxes.One has the picture I want to display to the user and the other has a picture that I use as an overlay.The overlay PictureBox uses a PNG image with a transparent background. However, every time I run the UserControl, the overlay does not display the transparent parts of the PNG image as transparent (It appears white).
When the dialog pops up, the screen dims down almost as if they overlapped the screen with a transparent black layer of some sort. This is easily accomplish able by creating a black form and having its opacity set to half and starting it maximized-which I'm already doing. The problem with this though is I need to do this within a form, so using a panel or anything is out of the questions since transparency really grabs the background image and not the actual controls underneath. Plus I feel if adding a form to another forms controls depletes it's ability to use it's opacity property.The form I need this in is my cash register. It is full screen but if my menu auto hides it still resizes. It has two parts, the order(panel to the left) and the payments(panel to the right). As you could imagine I want the payments portion blacked out until the order is capable of accepting payments(the payment due is greater than 0). Or I'm thinking it fallows the mouse, you mouse over the payments and the orders panel blacks out, and vice verse.
Plus I have tried googling this but no one seems to have the answer on other forums.. Everyone gets confused and the thread ends short with no solution. Apparently though experts-exchange has the answer, but wants me to pay... so no. Wish their site would stop showing up in my google results.But did have an idea of what I could do. My best guess was I could take a snap shot of just the panel I want to black out. Set it as the background image for that panel THEN use my overlay panel(back color sent to black) overlapping the appropriate section with it's transparency set to half.. But still I'm not sure how to take a snap shot of just a particular.control..
I've created a form (OpaqueForm), which is an intermediary form between other forms which I will open with ShowDialog. The idea is that when I want to show a form using .ShowDialog, this OpaqueForm, with an opacity other than 100%, sits in between the main form and the dialog form, effectively "greying out" the underlying main form.
The OpaqueForm has the FormBorderStyle property set to None, and accepts in the constructor a Form object on which it invokes .ShowDialog. The effect works fine, but there is one caveat. The task bar is also covered by the OpaqueForm; I am assuming because it has a FormBorderStyle of None and a WindowState of Maximized.
I don't want the OpaqueForm to cover the Task Bar, because it would be impolite to have my modal form lock out a user from switching between tasks. How could I go about preventing OpaqueForm from covering the Task Bar, too, while still using a FormBorderStyle of None?
I have a wonderful program which needs to be overlay-ed over my full screen directX game, the only problem is I can't seem to find any way of doing this with .net coding
things that don't work are, these are not overlays and will not work over a full screen directX game. I posted this so hopefully no one gives me that answer by mistake.
HTML
timer1.interval = 1 if timer1.enabled = true then me.topmost = true end if
the only thing I can seem to find is this example and source C# overlay maker however it's pretty old and it's for C# but maybe someone could convert it somehow to .net or something, I really need to find a way to do the overlaying tho been trying for months now...
I have a bit of an issue here. I made a "Colour picker" dialog in my program with which you can pick the colour at the mouse. It is a simple topmost form with an OnPaint handler used to draw a coloured border around the cursor:
It uses a transparency key to make the non-drawn parts of the form transparent.
It uses the following code to prevent the mouse from clicking through the screen:
It sets Layered to True and Transparent to False. This works in Windows 7, but on a XP machine it fails. When moving the mouse the event does not go to the forms' event handler and you can just click through. For a screen region selector I simply made a screenshot, but I want the Colour Picker to remain updated. (just in case you want to get the colour of an animated control)
How can I get this to work on a Windows XP machine?
Are there any datagridview controls from a 3rd party component companies, such as Telerik, that have a feature for merging cells or overlaying cells into one?
make a openGL overlay so for an examplei play a game and when i click shift + tab then the game will fade and my application will be seen but without minimizing the game
I'm about to lose my mind. I'm trying to make a touchscreen overlay for our crappy POS software at work. It is a simple DOS program. I had built an autohotkey script and gui but I just didn't like the look and lack of advanced menus. All I want is to replicate the CONTROLSEND ability of autohotkey. I tried the autohotkey.dll but I have no idea how to add it to my project. I was hoping VB2010 had something built in that can send a string of keystrokes to the DOS program underneath. I have searched all sorts of forum posts for a SIMPLE snippet of code. Seems anyone seeking this is out for nefarious purposes though, and little help is offered. If you worry about this please PM me so I can prove to you my good intentions.
Let me repeat, all I want is a simple snippet of code that when a button is pushed, a specific string (characters and function keys) is sent to a specific out of focus dos box.
I working on a distributed mediaplayer that uses the windows media player component.Now the customer asks me if its possible to have their logo overlayed on the media played instead of them having to render every movie with the logotype.I have google it and it seems like I can use a directshow filter to do this, but I havent found any good information on how to do it yet.If anyone here know If I can do this programatically, with a plugin, filter or some other way it would be nice to know. Its fine if its a plugin that costs money too. What I want is to be able to use a jpg/png as watermark/overlay to the running movie in Windows Media Player 11
I need to overlay the text, a movie or bitmap over a video.It would be possible to use VMR9 filters, but at playing of a wide video, for limits of a black square, it is impossible to overlay in out of video square range.
I need to overlay a small bar along the top of the screen over a fullscreen DirectX game. I have searched for a while but I have not found any code examples for VB.NET 2008 (I've never used any previous version). How can I do this? Would this involve learning DirectX programming?
In windows when you drag from explorer there is a custom "picture" when the items are dragged ... how can i do this in vb.net?
I know how to do drag drop but not with the picture...
also note: I DO NOT just want to change the cursor icon ... in explorer the drag picture can be bigger than 32x32 and i need it to be in my project also
