Visual Basic :: Resize Pictures With Antialias ??

Resize Pictures
I need a little help on this one, the user needs to be able to select a folder (got that taken care of) and the folder will contain a bunch of .jpg files. The program than needs to resize the images to 200x100 and save the resized image into /resized1 and then it needs to resize the original files again to 500x1000 and save those resized images into /reized2 and finally delete the original .jpg images in the root folder

thanks

Resizing Pictures In Form Resize And Multiple Resolutions
Hi, i have an application in which i have a picture box. the form is resizable, so the picturebox is supposed to resize too.

Is there an api or a property or control that lets me resize also the loaded picture, without bloating application resource size with adding multiple pictures of the same picture?

Antialias TTF
Does anyone have experience useing gdi to render an anti-aliased TrueType Font?

Antialias With Line W/o API Or DX?
I am using the line function with a large value for drawwidth to draw a path for a maze. The line function rounds off the ends of the lines, which is ok, but the curves on the white lines against a dark background are not smooth. Is there a way to implement antialias on line-drawing? Or is there a way to have the line function not round of the ends of the lines?

AntiAlias Text Please..
hello here is my code

VB Code:
Private Sub Command1_Click() With Picture1 Picture1.ScaleMode = 3 'Pixel .FontName = Combo1.Text .ForeColor = vbWhite .FontSize = Text5.Text .AutoRedraw = True .Cls .PaintPicture Image1.Picture, 0, 0 .PaintPicture Image2.Picture, 0, 0, 150, 150 Picture1.CurrentX = Text3.Text Picture1.CurrentY = Text4.Text Picture1.Print Text2.Text End If End With End Sub

now how do i make the text it prints AntiAlias ?

Can't Get DX7 To Full-Scene Antialias
Put simply... that's my problem. I've had it working fine in DX8 before, but now I've reverted to DX7 I'm struggling.

I've been through the SDK samples, directX4VB tutorials and a couple of other I found on the net, but I can't find a sample which even tries to use it.

So resorting to type.. dig in to the help file.

I've found the RasterCaps and found my system should be able to Antialias SortDependent or SortIndependant. I've set the Caps2 DDSCAPS2_HINTANTIALIASING flag, and ensured that the surface also has the DDSCAPS_3DDEVICE flag set before I create it.

I've Set the RenderState either SortDependent or Independent but alas no joy.

I think most likely I've missed something... if so.. WHAT?
or
it's working but it's not having the desired effect.

I attach noanti.jpg for your viewing "pleasure". Note - The thin strips are actually very thin textured 2 Primitive TriStrips.. rather than part of a texture or drawn as lines. Each Tile and strip is drawn seperately, though all the tiles are drawn, then the strips (probably).

The top strip shows what I get when looking "Top Down".. I've resized the actual screen shots so they are all the same size, but as you can see as I Zoom out some of the thin "strips" disappear completely... would antialias help here?

The bottom strip is from a "fly-around" view showing what I get as the camera moves.. the 45° image is "OK".. but at "lower" angles it starts looking awful. I'm sure antialias would help here.

So any help appreciated... if you know of (or have) a DX7 IM sample that you know uses Full-Scene antialias successfully I'd be grateful for a URL or an attachment.... I generally pretty resourceful but this is starting to get me down.

TIA

Drawing Opacity? Antialias?
I've been searching around for a way to be able to draw but with the opacity as something like 50% (just an example) on programs like paint shop pro you can change the opacity and hardness.

does anyone know if this is possible to do in Visual basic? i've got a feeling it can be done in VB.net.. but i don't really want to have to switch over to a new programming language (having to buy the software mainly, etc.)

is there a way to maybe add an antialias onto a picture.Line or change the opacity (so when you draw over other lines it builds up)

..maybe i've bitten off more than i can chew for this program :/

Antialias Text Control
Does anyone know how to antialias a label control? I've seen a couple examples of antialiased text but in a picturebox. I need it on the form this way. I would like it to support any font.

Any ideas?

Line Antialias Function
Does anyone have an antialias (smoothing) function that they have written for straight lines. I have thrown a function together but I can either spend more time on it or be lazy and hope someone else has already made a good one

How To Antialias The Edges Of A Form?
Hi, I'm working on an app in VB6. It will play animations on top of the desktop.

So far I have been able to:
Create a form that uses a colorkey to make the form transparent (cut out).

Put the form 'always on top' so that the form will always be visible.

Play an AVI-file in the form. When the avi is playing the form changes it shape since the colorkey transparency is applied to the entire form.

--------

All this sums up to an application that can play animations on top of the desktop. So far so good. However, the edges of the form is not very smooth and I would like to antialias them so that they look good on top of the desktop. It should be able to implement if I could capture the screen behind the form before the animation is drawn. I don't know how to do that though...

Another approach could be to somehow define a second colorkey which could be 50% transparent. The application could preprocess the avi-file and draw the edges with that color. It would not be the best 'antialiasing' but it would probably improve it. Right now, if the colorkey is black (000000) and there is a pixel on the edge of the form that is almost-black (000001) then that pixel will be drawn as part of the form. Of course, I have no clue on how to set up a second colorkey...

I know that the antialiasing works in theory because I can set a timer to hide the form, capture the screen, show the form and then use the captured screen to antialias the form. Doing this every 5 secs or so just isn't good enough. It's not only inefficient, it flickers too...

I would love to get some advice on this.

Metal Shine, Antialias Edges And Better Drop Off With Directional Light
Hello guys

I do not know if this is the correct forum to post this in, but anyway, here it goes.

I am developing an application(in C#) that uses directx to show some geometry. I am trying to make it as close as possible to the Viewpoint technology(www.viewpoint.com) regarding the GUI experience. I am not trying to develop a new format, nor to be able to show the geometry over the internet.

I have come quite close, and yet... then again.... I have some problems which I cannot solve:
1) Viewpoint gives the geometry a metal shine, which makes it look really cool? How do you do that? I have been trying to make it using material specular settings, but I totally burned (over lighted) the geometry. Is there a standard way to do this?
2) The edges shown by the viewpoint player are somehow antialiased, which makes the geometry look awesome. How can this be achieved using DirectX?
3) It looks like that the use of light are more manually made. It looks like it is a directional light, but that the angle between the normal and the light is controlled so the dropoff looks bigger. Can this be achieved using vertexshader in DirectX, or how can this be made?

Well, a lot of questions. I hope this is the correct forum for this.

Regards and thanks in advance for any answers,

Resize Objects(controls) In A Form Resize
Hello,
I have been searching this website for information about how to resize a form and the objects within that form, and I am getting more and more confused as I read. What I have is a form with some textboxes. I want to be able to drag the corner of the form to resize the form(or hit the maximize button at the top of the form) and have the textboxes resize accordingly(like how IE or Word does the resize). Please tell me that I do not have to find the ratio of each txtbox to the window and some how do a calculation to keep that true for all sizes. From what I was reading a problem with this is that it flickers alot and looks "ugly." It would be nice if it didn't flicker. I was having some problems reading some of the code and explainations that were posted in some of those threads. If anyone can help me out that would great. Thank you.

Resize Picturebox Contents With Form Resize.
Hi all.

I want my form to resize for different screen resolutions and I'm trying to adapt posted code to be able to do it.

This code is part of the Private Sub ResizeControls(). At runtime U draw lines into picture2 which is what needs to be resized.

I don't understand the Picture2.Picture = Picture2.Image part. Just trying to work out why it's not displaying what I've drawn.

Picture2.AutoRedraw = True
Picture2.Picture = Picture2.Image
ResizePicture Picture2, Picture2.Picture
Picture2.AutoRedraw = False

Resize The Form, Don't Resize The Command Buttons - How To Do?
Hi everyone,

I got a wonderful idea from Karl Moore at

http://vb-world.net/tips/tip489.html

to resize the form and the controls.

My problem is, i want the command buttons to remain in the same size, where as the other controls such as data grid changes the size.

How can I do that?

Your help is greatly wanted.

Thank you.

Resize Object By Resize (RESOLVED)
I am trying to resize an object, lets use a label as an example:
Private Sub Form_Resize()
label1.Height = Screen.Height - 1800
label1.Width = Screen.Width - 500
End Sub
Using this code will only resize to the size of the window, whereas I need the object to resize to the form.
Any help is greatly appreciated, Thanks in advance if I don't get back to you.

Resize
i don't wanna that my form be less than 3600 in height and 4800 in width.
i know that I may use this code :
Private Sub Form_Resize()
If Form1.Height < 3600 Or Form1.Width < 4800 Then
Form1.Height = 3600
Form1.Width = 4800
End If
End Sub
but this code is dirty hack cause this allows a form and after that it will resize to 3600 and 4800.
i wanna that form can't resize less than 3600 and 4800 at all
excuse me for my english

Resize Of An Ocx

How do I invoke a routine when a property changes?

how do i make my form full screen without pressing the button at the top

Resize
Hey I was wondering how to make the elements on my form resize when the user resizes the form. I already have the following code, which works great until you resize the width and height at the same time. The code I'm trying to use to handle that is in need of debugging and is in red.

Code:
Private Sub Form_Resize()

strWidthAdjust = frmRickEdit.Width
strHeightAdjust = frmRickEdit.Height

If strWidthAdjust > strFormWidth Then
picGradient.Width = picGradient.Width + (strWidthAdjust - strFormWidth)
txtCode.Width = txtCode.Width + (strWidthAdjust - strFormWidth)

ElseIf strWidthAdjust < strFormWidth Then
picGradient.Width = picGradient.Width - (strFormWidth - strWidthAdjust)
txtCode.Width = txtCode.Width - (strFormWidth - strWidthAdjust)

ElseIf strHeightAdjust > strFormHeight Then
picGradient.Height = picGradient.Height + (strHeightAdjust - strFormHeight)
txtCode.Height = txtCode.Height + (strHeightAdjust - strFormHeight)

ElseIf strHeightAdjust < strFormHeight Then
picGradient.Height = picGradient.Height - (strFormHeight - strHeightAdjust)
txtCode.Height = txtCode.Height - (strFormHeight - strHeightAdjust)

ElseIf strWidthAdjust > strFormWidth And strHeightAdjust > strFormHeight Then
picGradient.Width = picGradient.Width + (strWidthAdjust - strFormWidth)
picGradient.Height = picGradient.Height + (strHeightAdjust - strFormHeight)
txtCode.Width = txtCode.Width + (strWidthAdjust - strFormWidth)
txtCode.Height = txtCode.Width + (strHeightAdjust - strFormWidth)

ElseIf strWidthAdjust < strFormWidth And strHeightAdjust < strFormHeight Then
picGradient.Width = picGradient.Width - (strWidthAdjust - strFormWidth)
picGradient.Height = picGradient.Height - (strHeightAdjust - strFormHeight)
txtCode.Width = txtCode.Width - (strWidthAdjust - strFormWidth)
txtCode.Height = txtCode.Width - (strHeightAdjust - strFormWidth)
End If

End Sub
I'm also using a timer with an interval of 1 to update the variables on how big the form is:

Code:
Private Sub tmrResize_Timer()

strFormWidth = frmRickEdit.Width
strFormHeight = frmRickEdit.Height

End Sub
Can someone tell me what I'm doing wrong here?

Thanks in advance,
Kid

Non-Resize

Hi, i have a trouble with this...

I want to make my form to be not resizeable, but I also want to display the minimize button on the form. So the borderstyle property is useless in this case.

GDI+ HDC To HDC Resize
As the title suggests, I'm attempting to pass an image (which I'm having trouble creating from a HDC) to GdipDrawImageRectI.

I was passing a Graphics to it in place of the image and crashing the IDE.

I'm just using flat API, help!

I figured (searched and searched) it out. Used:

fgpBitmap.CreateFromHBitmap PicBuffer.Image.Handle
fgpGraphics.CreateFromHDC Environment.hdc
fgpGraphics.DrawImageRectI fgpBitmap.Handle, 0, 0, Width, Height

*slaps head*

P.S. Thanks OnErr0r, and well done!
