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

Jan 4, 2011

How 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?

Jan 3, 2011

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:

[1] load image into memory

[2] convert bmp files to jpgs if needed (for a smaller file size, mostly)

[3] load image tags into ImageData Structure (see below)

[4] load file data into ImageData Structure (where needed)

[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
Imports System.IO.Path
Imports System.Drawing.Imaging[code]........

VS 2008 - VB BITBLT Equivlant - Build Image By Opening Files With Image Data

Nov 2, 2010

In VB6 you could BITBLT things around before refreshing the screen. In .NET, I'm aware of DrawImage, but that can only be done on a paint event rather than before anything gets painted. The issue I have is, I need to open several files with image data in them and then build a bigger image with those smaller images. Before I could open them, BITBLT them to a Buffer. As far as I can tell .NET offers no way to do this as the only function I've been able to find (DrawImage) only works within the paint event. Is there still a way to do this in VS08 or no?

PictureBox - Image: Select The Path To A Local Folder That Is Within The Application And Get An Image From It?

Sep 15, 2010

I have a Picturebox and a two Buttons on my Form. On click of one of the buttons I want to change the image in the picture box at runtime.

This works fine when I give the location of the image (the full path ) on my computer - but then of course it will not work if I use the solution on a different computer .

So I have made a folder named "Pics" inside my application and added two images into it.

How do I get to this local folder in the following code?

Picturebox1.image = system.drawing.image.fromfile (??? )
instead of the usual,
Picturebox1.image = system.drawing.image.fromfile ("C:UsersMyName My PicturesMyPicture.jpg" )

Transparent Controls Over Form With Background Image Shows Backcolor Not Image?

Sep 18, 2009

I can't remember exactly if this is possible or not but what I am attempting I would think should theoretically be possible. I know it is possible in WPF but the company I am working for doesn't want to make the transition just yet. Basically what I want is to use a background image on a form for the background and I have a docked control on the right and left. I have set the background on both of these docked controls to transparent however it is showing the back color rather than the background image. I tried, rather than setting the background image property, to override the onpaintbackground and onpaint events and use e.graphics.draw(picture, me.clientrectangle) but it still seems to just pick up the backcolor as the true transparent background so I'm wondering if it's possible to get it to show the background image through the control rather than the backcolor of the form?

I can't check to see if it's done using the image so I wondered if there was a way to check to see if the file is writable. A small loop that exits once it becomes writable (or "deleteable").
