Load An Image, Change Individual Pixel Brightness And Save New Image?
Dec 22, 2009I am "weeks new" to visual basic 2008 but I was hoping that someone might tell me how I can open an image in whatever type of "visible" graphics window (always positioned at: x=0 y=0); move to some "definable position" of interest x=(n) y=(n); change the brightness of that "individual pixel" by some "definable means of measure" from its original state; and save the new image as a separate image file?

.NET Renaming File And Retagging / Edit Image MetaData / Meta Tags?
Jan 4, 2011How do I Edit and Save Image EXIF / Metadata / FileInfo without using an external DLL?
Project:I'm building an app for personal use to rename, retag, and organize the apocalyptic quantity of images I host on my personal website. As I have been collecting funny pictures and such for several years, there is no real rhyme or reason to the file naming conventions. Ergo, Image0001.jpg needs to be renamed to a descriptive filename, and the Metadata fields need to be filled in.
The desired process will take an existing jpg, gif, png, tiff or bmp and do the following:
load image into memory
convert bmp files to jpgs if needed (for a smaller file size, mostly)
load image tags into ImageData Structure (see below)

Renaming File And Retagging / Edit Image MetaData / Meta Tags?

[5] display image and tags for user to edit (In a Picture Box and several Text Boxes)
[6] allow editing of fields and renaming of the file
[7] write the changes to the image file
[8] go to next file.
Example:
[1] Load Image0001.jpg. Populate ImageData Structure fields.
[2] Type in Description: "lolcat ceiling cat sends son".
[3] ImageData.FileName changed to "lolcat-ceiling-cat-sends-son.jpg".
[4] ImageData.Name, .Keywords, .Title, .Subject, and .Comments changed to "lolcat ceiling cat sends son".
[5] Save file with new filename and save all new tag fields.
(Later, I will also be using SQL to build a referential database with links to the online copies of these files to allow for searching by keywords, subject, filename, etc, but that's another layer that's much easier than this one. At least to me.)
Problem:So far, several days of research have yielded almost no measurable progress. Information has apparently been inexplicably hidden behind a bunch of unexpected search keywords. Current Code as is:

Imports System.IO.Path
