Is there a simple way to get the width and height of a picturebox in pixels?
View 3 RepliesI drew an image in a picturebox with the image height as picturebox height and image width as picturebox width. The image is placed somewhere on the center of the picturebox. My intention is to scale the image to fit to the picturebox.

View 1 RepliesI'm trying to make a -what i thought would be simple app.My intention was to build program that:1) i'd provide a grayscale image2) the program would count the black pixels the grey pixels the more grey pixels etc. (the hue) and the white3) would make the percentage sum of all pixels, that is: 300.000 black pixels (rgb 0 0 0) etc. given that 0 is the black, 100 the white. e.g a simple grayscale image is 55.2 white
This was my way and i don't think that is useful:
First of a button to convert the image to greyscale:
Dim bm as new Bitmap(source.Width,source.Height)
Dim x
Dim y
[CODE]...
Secondly, -and that's the stupid way- i did -or better i wanted to do- this: i put the code to dynamically create labels, each label having the colour of a pixel as background colour and as text the colour converted to rgb
The third step which i intended to do (i couldn't get pas two) was to sum up the labels etc.
I save my images into my SQL Server Database with ASP.NET(2.0).
(imageData -> image) (imageType -> varchar) (imageLength -> bigint)
Thus the imageData will be "Binary data" and the imageType will be like "image/gif" and the imageLength will be like "6458".......
Is it possible to get the image HEIGHT and WIDTH from my VB.NET code inside my ASP.NET? I want to make my picture box on my web form the size of the actual image that is saved in my database.
I know to get an image's size if its a file, but what if it is located in the clipboard? I really don't want to save it from the clipboard as a file only to read its size.

My goal is to iterate through each pixel determining whether it is black or white. Ideally I want to do this one row at a time (so I can count the number of black pixels in each row). This is a bitonal image.I tried to get it started, but I don't understand what value(s) I'm supposed to be polling for. The following code takes a stab at it (i.e. makes a guess as to what value I'm supposed to check) and then outputs that value to a textfile.When I read the textfile, though, it doesn't look like anything useful.This code is an attempted modification of some code found in a CodeProject article.[code]
View 5 Repliesis there anyway i could count the number of say Black pixels in my picturebox say i have a picture in it that has 1 black pxiel i would like to to but that to a string so i could put it in a textbox or a msgbox like this
so in RGB black would be 0-0-0 but how would i have it scan the pixtuebox and count how many pixels show up with the rgb color 0-0-0
I see that the Line method is replaced with DrawLine, however; it seems like DrawLine must treated as an object as follows:
Private Sub Form1_Paint(ByVal sender As Object, ByVal e _
As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint
Draw a solid black line 25 pixels from the top of the form.[code].....

what is the height of a regular PDF page in pixels?
i heard it was something like this:
Dim pgSize As New iTextSharp.text.Rectangle(595, 792)
but i am adding an image that takes up maybe half the height, and even though pgSize looks like a full page and the image takes up only half of it, i am getting a height of like 619 for the image? i do not know if it is in the same units?
I know that you can return the length of a string, which results in the number of characters and spaces. Is there a way to return a width of the string in say, pixels,inches or some unit of measurement.

View 2 RepliesI am working on a report in Excel and there's potential for quite large amounts of text easily over-running a merged sell of maximum row height size. I therefore want to be able to merge the right amount of rows to make the text fit cleanly.My idea was to try and find the height of a string when limiting it's width - essentially placing a piece of text into some kind of container, making that container fit to size (with a set width limit, in this case 640 pixels), and measuring the height of that container. With the height of the said container, I could then work out the amount of standard sized excel rows I want to merge.I tried to use a label but there's no way to set only the vertical element to be autosize.

View 2 RepliesI have the darndest problem. One of my forms resizes itself. In the development environment the size is 605/301. When the program runs it is much larger. In the form_load event I put the me.Width & me.Height commands and it still is much larger. I looked at the "hidden" windows forms code and can't see any resizing going on. I added a msgbox with the width & height. It says 605 & 301, yet the form is much larger.
