imagetoolbox's Issues

Italian translation

Hello,
I would like to add Italian translation to the app. Could I work on it?
Thank you.

What the airplane icon do??

I just saw the new paper airplane icon on the top bar, and I'm wondering what it does.... It seems to be some kind of preset?

[New Tool] Change Hue

Please add a new tool for changing hue:

VID_20230316_164050_636.mp4

Thanks 🙏

[Feature request] Resizing with fitting width and height

I suggest that let users specify a range instead of a fixed size for resizing by WidthLimit or HeightLimit depending on the image aspect ratio.

if the image width or height is greater than the limit, and...

• the image aspect ratio >= WidthLimit/HeightLimit
  then resize by WidthLimit.
• the image aspect ratio <= WidthLimit/HeightLimit
  then resize by HeighthLimit.

For example WidthLimit=800, HeightLimit=800

• image1: 4000x3000 -> 800x600
• image2: 3000x4000 -> 600x800
• image3: 400x300 -> do nothing
• image4: 300x400 -> do nothing

Aspect ratio

Please add the support aspect ratio for cropping pictures. (Like the Snapseed app)

Add ability to retain aspect ratio

It would be nice to have a lock ration button so we can resize images without distorting them

Improve the crop feature

Please improve the crop feature.
I can change the aspect ratio when I locked it.

VID_20230307_172030_872.mp4

Snapseed is working fine:

Images don't save.

Tapping the save icon does nothing.

Device: Pixel 7, Android 13.

Also, there's no padding from the bottom navigation bar in the UI. There should be some spacing there.

Show as image editor

Hi, I can't see this app as an image editor.
I want to use your app to crop my photos.
Please fix this issue.
Thanks 🙏

feature req. jpg support (not jpeg)

This is a very popular format that my camera works with

F-Droid inclusion

While your app is already listed in my repo, someone opened an inclusion request with F-Droid – where issuebot complained about missing fastlane structures. With your app listed in my repo I have already set them up. Originally I wanted to provide them to you via a PR, but Gihub is currently stuck when trying to fork – so find the files attached below.

Simply unzip the archive to your repo's root, then add and commit the changes. Be welcome to update the description, replace the screenshots, add a featureGraphic, add per-release changelogs, additional locales – as you wish: it's yours 😃 Be welcome to use my Fastlane Cheat Sheet for guidance.

fastlane.zip

Btw: that "someone" (literally: "Somebody") ticked the box of having you (the author of this app) informed and stating you're not opposed to inclusion, so you're probably aware already.

feature req. in batch resize

the ability to crop a photo for only one photo (the one I choose in the preview photo (#19))
Also, it should say that this will only work for 1 photo

Equalizing the images in the comparison tool

In the comparison tool, the images must be the same size:

video_2023-03-19_14-23-22.mp4

Implement AI super resolution scalers

I was wondering if there's any chance to include AI super resolution scalers like Waifu2x, RealSR, etc. for upscaling images? These scalers can work if there's Vulcan support and binaries can be found here.

Update photos in f-droid

Dynamic color is broken

When navigating to any page from the homepage and then coming back, the color scheme changes to green which seems to be the default option under the "Color scheme" option, although this should be disabled as "Dynamic colors" option is enabled.

feature req. resize video

this is as important as the photo (for me)

I would like to see the same functionality for video

right now there is no resizer for video (open source) and your app is absolutely perfect for photos, it would be good if you added resize video. Then it would be a multifunctional app, which I also need

Many people need it, I think

Copycat/Clone of ImageResizer on Google Play

Hi,

I just found this copycat of your app on Google Play https://play.google.com/store/apps/details?id=ru.tech.imageresizershrxcver from this developer.

It's full of ads. It might be a violatiton of Apache V2 since I can't find the license and the changes he made to the app.

People from Newpipe wrote a procedure to report the app to Google Play that I collected here in a gist if it's of some interest for you.

feature req. in batch resize

Now only the first picture is shown in the batch resize

I suggest adding a button that, when clicked, opens a menu with a choice of "which photo to view? There will be the number or names of all the selected photos, clicking on one of them will open this image

This is to check if I resize correctly for each photo

Allow use of own file selector

Hi, can you add an option where i can select my input pictures from my gallery app of choice.

Vertical Compare

Thanks for creating this app and compare tool.
Please add the vertical comparison tool.

Thanks 🙏

Add presets of resizing

App crash when resizing bigger

Hi,
When i select resize to JPEG + maintain aspect ratio.
If i add more numbers into the width to resize bigger, the app crashes.

Save Location

Resized images appears on Camera folder of Google Photos because images saved under a subfolder in /sdcard/DCIM. Could you move the subfolder to /sdcard/Pictures ?

Add a facility to compress the image to a specific size

It will be helpful if an option to compress the image to a specific size (in MB, KB) has been implemented.

Romanian translation

Hello, i translated this app in romanian from weblate. So, can you add it in the next update if posibile?

Batch resize

Please allow user to mark and resize multiple files at once.

Rename the app

I suggest you rename the app to "Image Tools"
The app is more than just an image resizer.

Error while opening an image

When opening an image, i got the following error:

Bad rendering of translated text in top app bar

I'm working on Italian translation (#31) and I noticed that in the Batch Resize activity the English title fits perfectly, while the French and the Italian strings, which are longer, overflows.

Default language (English)

French

Italian

I came up with two possible solutions:

• In the composable function, set a text size smaller than the default language for French and Italian, something like this:

if (app is using the default language){
    // Render text in the default size
} else if (app is using the French translation) {
    // Render the text optimally for French strings (maybe with a small text size)
} ...

• Apply a marquee behavior to the text that overflows.

Also I got suggestions here and here.

Fix single crop

Image is always scaled to 4k after crop in single resize mode

Share an image or group of images with Image Resizer App

Is it possible to add feature Share an image or group of images with Image Resizer app to change the qualit?

German translation

Sorry, but German translation of "Resize by weight" (Größenänderung nach Gewichtung") doesn't make much sense. Of course, it's not colloquial in German to speak of the "weight" of a file in terms of size. So the related term "Gewichtung" is a bit misleading, as it's more linked to "evaluation", "ranking" than to the sought meaning. Obviously, as a repetition of the word "size" should be avoided, you could use "Volumen" ("volume", "amount"). So the whole item would be: "Größenänderung nach Volumen".

Otherwise, nice app (also nice UI). Thank you!

PNG extension

When I choose PNG extension image compression doesn't work
Why?

For example
https://github.com/caydey/ffshare

Works with png

feature request: Resize image in cm or mm

Hello....Is it possible to add Resize option in cm or mm. Resizing in pixel is great but most of online application requires images to be in cm or mm.Thanks
