TPU.org specific size limitation

[FordGT90Concept]

It says 2 MB but does that mean:
2 MB = 2,000,000 bytes
or
2 MiB = 2,097,152 bytes

 

[n-ster]

test it yourself? it cant be that hard

(not trying to be mean, sry if it came out that way)

 

[n-ster]

Well I tested it with a 1.94MB image I found online:


http://img.techpowerup.org/110401/Cover-GGCC(2mb).jpg

Which is something like 2039000 bytes, so my guess is 2,097,152 bytes

though if you "save image as" it is 2.12MB with the watermark... weird

http://img.techpowerup.org/110401/Capture115.png

left one is original, right one is save image as from tpu.org

 

[FordGT90Concept]

1.98 MiB (2,085,232 bytes) file accepted:
http://img.techpowerup.org/110401/2MiB.png

So it is 2MiB.


Edit: 2.50 MiB (2,622,506 bytes) watermarked. XD

Here's the result of why I asked (attached). It's a commandline, .NET 4.0 application (Client Profile will NOT work):

Spoiler: TpuResize

tpuresize "in" [-out "out"] [-x pixels] [-y pixels] [-size mebibytes] [-fill colorname] [-transparency colorname] [-notransparency]

in = Path to the input file. For example: "C:\mypic.png"

-out = Optional. Where to save. The extension of the file determines its "save as" type. Currently, only JPG, GIF, and PNG are supported. If not one of those three, it will try to save as the same type of file that was input. For example: -out "C:\folder\pic.gif"

-x = Optional. Limit the width of output image in pixels. For example: -x 1920

-y = Optional. Limit the height of the output image in pixels. For example: -y 1200

-size = Optional. Limit the size of the output image in mebibytes (2^20). For example: -size 10

-fill = Optional. Fills the entire picture with a single color before pasting the image on. This color will show through transparent areas of the image. For example: -fill white

-transparency OR -transparent = Optional. Color to make transparent when saving as a PNG. Here's the color names it will accept. For example: -transparency white

-notransparency OR -notransparent = Optional. Removes all transparency effects during the conversion.


You can drag and drop an image on it and it will default to the following (what is required by techpowerup.org):

tpuresize "%" -out "%_resized.jpg" -size 2

A random example using all parameters:

tpuresize "C:\mypic.png" "C:\folder\pic.gif" -x 1920 -y 1200 -size 10 -transparency white

The order they appear in does not matter as long as a command (starts with -) is followed by a value.

Spoiler: TpuResizeBatch

tpuresizebatch "file0" "file1" "file2" "..."

When it is first ran (must have a file in the commandline), it will create a tpuresizebatch.ini which has mostly the same settings as TpuResize. The one exception is "AppendFileName" which behaves similar to -out. This is the most important parameter because it determines the output file type. JPEG, JPG, GIF, and PNG are supported. Default is "_resized.jpg" (same as TpuResize).

Recommended to extract before running either application.

Wow I just came across the need for this the other night on GN....what a coincidence

Thanks Ford

or you could use imagemagick for win32

Not all of use can use spells...

Imagemagick does not do what this app does (make an image fit within x, y, and/or file size constraints) as far as I can tell.

there are lots of options for scaling but nothing to target a specific file size

 

[FordGT90Concept]

Exactly. This app is also tuned specifically to TPU.org so it will make almost any image acceptable to upload by simply dragging and dropping the image on the executable.

 

[Disparia]

-define jpeg:extent=2MB

(though I'm not on my box with IM setup to test if it takes in MB, MiB, or Mb as expected).

Probably good in conjunction with -type optimize.

 

[newtekie1]

Is it possible to change the output image type from the input?

 

[Easy Rhino]

Is it possible to change the output image type from the input?

with imagemagick yes, i dont know about tpu.org though.

 

[FordGT90Concept]

Is it possible to change the output image type from the input?

Yes, just use -out and give it a different extension (like .jpg). It will only convert when the out extension is JPG, PNG, or GIF (the types TPU.org will accept). If out is not one of those three, it will attempt to preserve the same format as input.


It's supposed to be -transparent instead of -transparency but, I added both so either will work in 1.0.1 (uploading shortly).


Edit: Uploaded.

 

[FordGT90Concept]

Uploaded 1.0.2 which has -notransparent and -notransparency flags.


Uploaded 1.0.3 which has the -fill flag.

 

[Deleted member 67555]

Ford this app rocks....drag drop no thinking required.....perfect

 

[FordGT90Concept]

Heh, yeah. I use it on virtually every image I upload to TPU.org--if only to convert the image to JPG from PNG. So much faster than doing it in MS Paint.

 

[theJesus]

Will this do batch operations?

 

[FordGT90Concept]

Nope because of all the options although a batch could be written to call it over and over again.


I could make a separate executable that is intended for batch operations using the default settings and the settings can be modified via INI or XML file. The "-out" flag would obviously be omitted though.

Edit: Programming note: Program.MakeItFit (what does all the work) is publically accessible so any .NET program could call the function within the executable.

 

[theJesus]

Do that and have it automatically upload the images and I'll love you lol

 

[FordGT90Concept]

W1zzard would have to approve the automatic uploading and probably have to make some changes to facilitate it. That would also require making a Windows application to show individual upload progress.

I can make a batch-friendly version though (drag and drop many files) relatively quick though...

 

[theJesus]

I'm sure the batch-friendly version would be useful for many members.

In regards to automatic uploading, yes W1z would have to approve it, but I don't think changes would need to be made. TPUCapture already has automatic uploading.

 

[FordGT90Concept]

Have a preference for INI or XML? I prefer INI but I can do either. INI would only have one file and XML would have two (XML and DTD).

I am going to make it create the config file if it is not found so the config file is easy to reset/access.

 

[theJesus]

I prefer INI as well.
