Touchscreen support HP Pro x2 612 G2

[Hans G. Schütz]

Hi,

first of all, thanks a lot for this great image viewer. Exactly what I was looking for!

I'm using it on a HP Pro x2 612 G2, Win 10 Pro 64-bit with touch screen. I have both ImageGlass versions installed: 8.6.7.13 as well as 9.0.2.904 beta 2.

I recognize a way different behavior using the touchscreen:

Ver. 8 allows to zooms in and out using pinch gestures. A bit jerky, but working. But I cannot move the zoomed image. As soon I use one finger trying to drag the picture up or down it zooms in and out instead. Trying to move picture left and right goes to the previous or next picture in folder.

Ver. 9 allows to drag and drop the zoomed in picture with one finger, but does not support a pinch zoom.

Is there a setting in Ver. 9 to activate zoom gestures?

Additional remark: when running both versions side by side, the zoom quality of version 9 is not as good and crisp as version 8 is. As I use ImageGlass for tech drawings (lines etc.), the zoom quality is very important to me.

Thanks for you answer in advance!

Best regards

Hans

Hi Hans,

The v9 (beta) is under development and does not support touch gestures yet, but interestingly, you mentioned you could pan the image by 1 finger.

I don't have a touch device to test it yet.

Additional remark: when running both versions side by side, the zoom quality of version 9 is not as good and crisp as version 8. As I use ImageGlass for tech drawings (lines etc.), the zoom quality is very important.

V9 supports hardware acceleration using Direct2D, the support for interpolation mode is different. The available modes are:

- NearestNeighbor (default when zoom > 100)

- Linear (default when zoom <= 100)

- Cubic

- SampleLinear

- Anisotropic

- HighQualityBicubic

There is no setting to change this yet.

V8 uses GDI+, which is slow, and not recommended nowaday. But it has more interpolation modes:

- Low (default when zoom <= 100)

- High

- Bilinear

- Bicubic

- NearestNeighbor (default when zoom > 100)

- HighQualityBilinear

- HighQualityBicubic

1. What zoom optimization setting are you using in v8? You can check it in Settings > Image > Zoom optimization

2. Can you share screenshots of both V8 and V9 to compare?

Thank you!

Hi Phap,

yeah, ver 9 is panning very good using one finger. It acts exactly as it should in my eyes!!

In ver 8 I'm using the standard setting for zoom (did not change it) ... settings say Auto (Low quality/Nearest-neighbor).

Regarding the zoom quality: I played around a bit with different drawings etc. I think late at night my eyes fooled me ... now, I cannot see disturbing differences in the quality. I will keep an eye on it, but I think we can forget about this.

Three additional questions:

- is there a json setting available, to start borderless (no windows title bar etc.)? Can't get rid of the title bar.

- I managed to customize the toolbar, also got the buttons for rotate left and rotate right, but I guess the function is not implemented yet ... because it's not working.

- is there also a admin.json settings file available as in ver 8? Would be excellent to fix all settings against accidental change.

If I could be of any assistance regarding zoom +/- touch gestures, simply let me know!

Thx, and best regards

Hans

v9.0 beta 2 does not support Frameless window mode yet! But you can use Full screen mode (F11).

- I managed to customize the toolbar, also got the buttons for rotate left and rotate right, but I guess the function is not implemented yet ... because it's not working.

Yea, in v9.0 beta 2, only flipping images is implemented. See the supported features in

- v9.0 beta 1 at https://github.com/d2phap/ImageGlass/releases/tag/9.0.1.514

- v9.0 beta 2 at https://github.com/d2phap/ImageGlass/releases/tag/9.0.2.904

(expand the Changelog)

- is there also a admin.json settings file available as in ver 8? Would be excellent to fix all settings against accidental change.

Yes, similar to v8, it has 2 other config files: igconfig.default.json and igconfig.admin.json.

You can even pass the setting as a parameter when launching ImageGlass. For example, to hide the toolbar and set background color to red

ImageGlass.exe -ShowToolbar=false -BackgroundColor=#ff0000

Hi Phap

thanks for your infornation! As I use ImageGlass as part of other (self programmed) windows on one screen, I can't use it fullscreen.

So, I will wait and hope to see those valuable features (borderless, rotation and perhaps pinch zoom) in another beta.

Thanks for all your efforts and best regards!

Hans
