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?
Is there a simple way to get the width and height of a picturebox in pixels?

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.

View 3 RepliesI have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.

View 16 Repliesi`m trying to find in cm or mm the area of a frame (capture image).The picturebox has dimensions height:456 and width:553 PIXELS.So the total number of pixels are 456 x 553 = 252,168
If i compare image 1 with image 2 i can locate and draw a rectangle around that area of pixels that are different.i can get the width and the height of this rectangle in PIXELS.e.g Height:49 Width:33 PIXELS
How can i covert these into cm or mm. What i need to know for the conversion?
I know dpi: dots per inch but what`s the value for my rectangle?
I would like to believe that this code will display a horizontal line halfway across the PictureBox pbxData. In fact, what it does is create the BitMap and then blow up with a memory violation when trying to copy the BitMap into the PictureBox. The code that alters the array is commented out because I don't know how to address the elements of the array.
how to make this into useful code?
