View 1 RepliesIn the process of creating an Icon object, I need to reduce the numbers of colors in an image from thousands down to 256 or less. I do this by "chromatizing" the RGB values - counting the colors - then re-iterating the process with heavier "chromatization" until the number of colors is reduced to my requirement.
I searched these forums and google on this subject to find out more - but I found that I alone call this process "chromatization" it seems. So I was hoping someone could help me out with the correct terminology.
Specifically, I want to use the correct terminology on my UI buttons (at present I have a button labeled [Chromatize] . .) and I am curious as to whether it would be good practice to "chromatize" the Green most heavily, the Red more moderately, and the Blue least . . . or just "chromatize" them all equally which is what I have been doing

I'm a VB beginner.I've been playing with Graphics.DrawString by watermarking a picture with a text string. The picture below to the left comes from PictureBox with a text string drawn with Graphics.DrawString. The font style used is Arial 48 points, regular, I think. The picture in PictureBox shows just as I configure. Great... The resolution of the original Terri Hatcher picture is 300 dpi (300 x 300). Exporting this picture with Graphics.DrawString, I get the picture below to the right. The text string appears a lot bigger than previously shown in PictureBox. It turns out that the text size varies, depending on the resolution of the original picture. That's kind of odd. I develop several graphics applications in a different environment and have never seen this sort of graphics.drawstring thing. Anyway,
my sample application seems to draw a text string at an image resolution of

I have a database application in which a user can add up to 6 pictures to each record. This pictures are not directly saved in the database but in a sub folder of the applicvation folder. Now, the problem is that lots of the pictures of users were taken on a digital camera with highest resolution - in these days it means that the picture files have a file size of 3MB.I would like to reduce the file size / resolution of the picture, so that the database can load and view this files more smoothly (I am not in need of a thumbnail preview, just want the pictures being a bit smaller).
The way pictures get attached / linked / 'inserted' to a database record is via OpenFileDialog. When a user selects a picture file it gets copied into the applications picture folder and renamed to the record ID of the actual record + number of the pic added.How could I reduce the picture size during adding it (OpenFileDialog / copying to folder)?

I made a picture box and imported an image named Title.jpg. Later I made adjustments to the picture and imported it again without deleting the original(mistake). The new one had the name automatically changed to Title1.jpg. So I deleted the original image from resources and renamed Title1.jpg back to Title.jpg.
Now I got two problems. First, only Title.jpg is on the solution explorer, but Title1.jpg(along with Title.jpg) still pops up on the resource list when I click on Image property of the picture box. There's only the name and no picture, and I don't see a delete option. How do I get rid of it? Second, even though I changed the image to the new Title.jpg in the picture box, the old one is displayed when running the app. What's up with that?

I have just found that if a DataGridView image column's size (height & width - in pixels) is smaller than the image's original size (in my case all images are exactly 180 x 180 pixels) at the time the cell is populated then the image is automatically being converted to a lower resolution I assume to fit the image completely within the size of the cell). How can I stop the automatic scaling of the image?
The image below show the same file displayed twice, both at 60x60 pixels ('Thumbnail' column) and a blowup of the image (PictureBox populated via the CellMouseEnter event) to it's right. You'll notice the resolution of the first blowup is far less the the second. so, what made the difference in the resolution of the blowups is? In the second blowup's case I'd first stretched the image column's width to ~180 pixels and set the row height to match (via the ColumnWidthChanged event) then populated the DataGridView then stretched the image column to 60 pixels (its minimum).

View 1 RepliesI have a picture box in a panel control. I want to be able to scroll the image in the picture box. I have added two separate scroll bar controls (Vertical and Horizontal). When the control loads, it load the image properly. However when i scroll the scroll bars, the image vibrates but does not actually scroll. Is there a property I need to set in the picturebox? I am assuming that when the picturebox loads the image that it defaults to Normal. Thus the image is clipped. Does this mean that I cannot scroll it? I have tried the other SizeMode properties (Stretch, AutoSize, Zoom etc). But I still cannot get the image to scroll.
